Today we are going to look at how to how to install Nginx Proxy Manager on a Raspberry Pi!

If you’re exposing any services on your network, using a reverse proxy is a great way to increase security and performance. A reverse proxy is a server that sits in front of your web servers and forwards client requests to the web servers. In layman’s terms, you only have to expose one server (using ports 80/443) and will be able to expose as many web services as you want.

This is an example of the network flow of a reverse proxy (simplified):

nginx proxy manager raspberry - reverse proxy setup which allows one server to be exposed which will automatically expose multiple other servers if configured

This tutorial will utilize a Raspberry Pi, which is great for home use, but if you’re hosting anything with a lot of traffic, you’re probably better off using a more capable server. We will check the status of the application after it’s finished installing by using Portainer, but this isn’t required.

Instructions – Nginx Proxy Manager Raspberry Pi

Ensure that Docker is installed. If it’s not installed, you can learn how to install it here.

1. We need to use docker compose to create the Nginx Proxy Manager container. This requires us to install a few dependencies – run the install commands below in order.

sudo apt-get install -y libffi-dev libssl-dev
sudo apt-get install -y python3 python3-pip
sudo pip3 -v install docker-compose

2. After the commands finish installing, we need to create a folder where our config and docker-compose files will exist. We will then navigate to that folder and create a file named config.json.

mkdir nginx
cd nginx
nano config.json
make nginx folder and create a config file

3. Paste these contents into the config file.

{
  "database": {
    "engine": "mysql",
    "host": "db",
    "name": "npm",
    "user": "npm",
    "password": "npm",
    "port": 3306
  }
}

4. Save the file and exit it. Create a new file named docker-compose.yml

nano docker-compose.yml
nginx proxy manager raspberry - create docker-compose file

5. Paste the contents below into the docker-compose file.

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./config.json:/app/config/production.json
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
  db:
    image: 'yobasystems/alpine-mariadb:latest'
    environment:
      MYSQL_ROOT_PASSWORD: 'npm'
      MYSQL_DATABASE: 'npm'
      MYSQL_USER: 'npm'
      MYSQL_PASSWORD: 'npm'
    volumes:
      - ./data/mysql:/var/lib/mysql

If you receive an error and the container will not start and is running as “unhealthy”, please follow the instructions below:

Special thanks to Plan945 for commenting with the solution.

Replace this in the docker-compose.yml:

image: 'yobasystems/alpine-mariadb:latest'

With this:

image: 'yobasystems/alpine-mariadb:10.4.17-arm32v7'
nginx proxy manager raspberry - docker-compose settings

6. Save the file and exit. You should have two files that exist in the nginx folder. Run the command below to start the docker container.

sudo docker-compose up -d
nginx proxy manager raspberry - create the docker-compose container

7. The container will download and install all the necessary files.

8. We will now adjust both of the containers that Nginx Proxy Manager uses to automatically start when your Raspberry Pi is rebooted.

sudo docker update --restart always nginx_app_1
sudo docker update --restart always nginx_db_1

restarting nginx proxy manager container
9. Restart your Raspberry Pi – very important!

sudo reboot now

10. After the reboot is complete, the container will take a few minutes to fully install. You can run the command below to check on the status of the container. When it reports “healthy”, you will be able to navigate to the Nginx Proxy Manager website. Alternatively, if you setup Portainer, you can open Portainer and check on the status of the container there.

sudo docker ps
show running containers

11. Wait for the status to change to healthy.

nginx proxy manager raspberry pi - status in portainer shows as healthy

12. Navigate to the IP address of your Raspberry Pi and port 81.

http://[RASPBERRY_PI_IP]:81

13. The default email address is admin@example.com and the password is changeme. When you log in, you will be asked to change this information.

nginx proxy manager login page

14. At this point, Nginx Proxy Manager is fully installed. You will need to open ports 80/443 on your router to point to your Raspberry Pi. From there, you will have to configure Nginx Proxy Manager. The majority of people will use Nginx Proxy Manager as nothing more than a proxy manager. I’m not going to go through the process of configuring a service as this will be different for everyone, but check out the video if you’re interested in seeing how it can be used as I went through an example there!

Conclusion

If you’re exposing services on your network, using a reverse proxy is a great idea. A lot of people don’t have a need for a full server running Nginx Proxy Manager, so a Raspberry Pi is a great option in that case. It runs well and is somewhat simple to setup.

    Reinstalled nginx_app_1 does not go to healthy log writes only info and no errors unfortunately I do not know here more further
    Do you know anyone who has had this error?

    1. WunderTech

      I unfortunately don’t. Everything that I already suggested are the items that I’d check. I promise that I’m not withholding information, I just haven’t run into that error before 🙂

  2. chrisi

    But a pity

  3. chrisi

    Thanks I thought so but thank you

  4. chrisi

    ?

    1. WunderTech

      I’m unfortunately very busy and don’t offer 1-on-1 support at this time. The instructions shown are what has worked for me, but individual factors can contribute to different issues.

  5. chrisi

    Dear Wundertech

    You can write me a mail regarding this if you want to

    Thanks in advance

  6. Chris

    Can you reach them where in a chat that we do it together ?

  7. Chrisi

    Yes the DDNS is displayed in https:// and the certificate from Lets Encrypt too.

    In the browser I can call the 192.168.x.x:8080 but Reg. does not work either see previous post.

    What else can I do?

    lg

    1. WunderTech

      I don’t think you’ll be able to register without using a valid SSL certificate, which is why the IP address won’t work. Unfortunately, I’m not entirely sure what it can be, but if you can get the DDNS hostname + SSL certificate working, you should be able to register.

      1. Chrisi

        SSL page opens but another internal page, Lets Encrypt Cert. I can download, in the browser is “Secure” therefore it can not be the Zert, only on what is the question

      2. Chris

        Hello

        nginx_app_1 is in my nginx always only running and not healthy

        This could be the reason can I send you somehow the log of nginx_app_1 maybe you find the error because in the net I do not want to post it thanks

        thx

        1. WunderTech

          I unfortunately won’t be able to solve the problems with logs only, though I wish I could. If you can, I’d start over and see if you can pinpoint where it’s going wrong.

    Dear Wundertech

    When I try to create a new Bitwarden account with a master password I get the following error message:

    PS: Release ports as described

    Browser entered the IP:8080/#/register?email=bitwarden@xxx.at comes the following:
    This browser requires HTTPS to use the web vault
    Check the Vaultwarden wiki for details on how to enable it

    because if I call the DDNS address that appears in the Nginx no login is possible.

    What else can I change

    1. WunderTech

      In the URL, are you using HTTPS? Do you see a valid certificate?

  9. Chris

      Sorry for not getting to your messages in time. Since you’re using a firewall, did you allow access on that port? Is the port properly opened from the outside?

  10. Chris

    Hi worked with this command now I come to the Nginx Proxy Manger am logged in

    docker-compose up -d db

    Thanks

  11. Chris

    Hello,

    -I can access Bitwarden Local.
    Bitwarden runs great locally on port 8080

    -nginx_db_1 which also works correctly:
    MySQL init process done. Ready for start up.

    Error:

    -on nginx_app_1 this error comes every seconds:

    Yes firewall I have an EdgeRouter X v2.0.9

    I hope you can help me with mom with my knowledge at the end

    greetings Chrisi

  14. Chris

    Hello

    I have the problem that the nginx_app_1 changes from running to healthy in the portainer.
    There is always an error message in the loga every seconds :
    [Global ] ‘ ✖ error connect ECONNREFUSED 172.18.0.2:3306

    And when I want to log in to the Nginx Proxy Manger to change the default password it always says Bad Gateway in red below
    Have installed everything as described
    Does anyone here know a solution, would be very grateful for your help
    thx Chris

    1. WunderTech

      I’m sorry to hear that it’s not working. When you view the container, do you see any specific errors? Are you using a firewall by any chance?

  15. Ashley B

    Thank you for the tutorial – very informative!

    I have attempted to follow it through on my Raspberry Pi 3B but when starting up the ‘nginx_app_1’ container, Portainer shows it as continually ‘Unhealthy’ with the output being ‘parse error: Invalid numeric literal at line 1, column 7 NOT OK’.

    Just seems to be looping, and it means that when trying to login to Nginx Proxy Manager, it just returns ‘Bad gateway’.

    I don’t suppose anyone has any ideas on how to resolve this?

    Thanks!

    1. WunderTech

      Thanks so much! Have you tried the suggestion in the tutorial (replacing the database in the docker-compose file)? It’s this if it would be easier to read it here:

      Replace this in the docker-compose.yml:
      image: ‘yobasystems/alpine-mariadb:latest’

      With this:
      image: ‘yobasystems/alpine-mariadb:10.4.17-arm32v7’

  16. Michael

    hello, thanks for the tutorial it saved hours of headache. I noticed when you are setting the nginx_db that you are using npm as the UN and PW. Is this a bit unsecure and if it is can you put your own username and password instead?

    1. WunderTech

      Yes, those were default values for the tutorial. Feel free to change them to be whatever you’d like!

  17. Shadex

    BTW I did use the fix with the other image for mariadb, but ended up with the same issues

  18. Shadex

    Im actually having the same problem as the one above where my nginx_app_1 is always showing unhealthy but can’t figure out why in the logs this is stated:

    [cont-finish.d] executing container finish scripts…
    [cont-finish.d] done.
    [s6-finish] waiting for services.
    [s6-finish] sending all processes the TERM signal.
    [s6-finish] sending all processes the KILL signal and exiting.
    [s6-init] making user provided files available at /var/run/s6/etc…exited 0.
    [s6-init] ensuring user provided files have correct perms…exited 0.

    !!!!!

    1. WunderTech

      What OS are you running this on? Is it Raspberry Pi OS?

  19. prisoner

    I have armv6l and my nginx_app_1 is always showing unhealthy i have tried both docker composer but didnt helped what might be wrong.

    1. WunderTech

      Are you receiving any errors in the log files that could point us in the right direction?

  20. gzah

    I did this install 3 months ago on my rasperry pi 4. It worked just fine until now. But now i need to renew the SSL certificate. I tried to that in nginx Proxy Manager. It did not work. Renew does give a timeout while deleting and redo ends in a timeout.
    Therefore i wanted to update from my actual version 2.8. But as a linux noob i don’t no how to that other than reinstall everything. How can i update nginx? I hope the update fixes the problem with SSL certificates from letsencrypt.

      1. gzah

        Thanks, i will try that.. that looks great!

        My SSL Cert is now working again.. My Raspi is running Ubuntu 20.10 running. I installed it as you described. Additionally a pihole is running i another docker container. Everything worked the whole time just fine!

        ..but there was most of the time the strange situation that i did not had a working internet connection on my Raspi. You can recognize this in Ubuntu by the network icon in the upper right corner. If a problem is displayed there the internet connection is not working properly. I also tried to reach a website.. it did not work!

        Then i deactivated the DHCP Connection and inserted a new manual configured connection with the same values. After that the networkicon in the upper right corner turned into online and suddenly the internet worked again as the SSL certs.

        I don’t understand why my nginx and the pihole worked the whole time while i could not connect the internet from my Raspi. how do the two containers get on the internet while no website is accessible in the browser?

        1. WunderTech

          The only thing that I can guess is that the DHCP lease expires and it has trouble registering that connection. Manually setting it will fix that, which is why you might not experience any trouble when you do manually set it. As for why it continued to work, I truthfully don’t have an answer. There could be tons of reasons, but you’re probably on the right track in thinking that something might be off!

      2. gzah

        Updating the containers did work as a charm!

        You have to click on each container to reach container details. There you can recreate the container.

        It worked with all my 3 containers perfectly!

        Now i would like to update portainer. I found the following manual: https://documentation.portainer.io/v2.0/upgrade/upddocker/

        Sorry once again for me is not clear what to do. Docker Standalone Installation, Agent Only Upgrade, both of them?

        1. WunderTech

          Glad it worked! Updating Portainer will have to be done through the terminal. I believe there is technically a way to update Portainer using Portainer, but downloading the latest image and recreating the container through the command-line is probably your best bet!

    Well to add to this above, I also have the “Unhealthy” Nginx issue,

    My scenario:

    Raspberry Pi 4 – Pi OS Lite (Linux raspberrypi 5.4.83-v7l+ #1379 SMP Mon Dec 14 13:11:54 GMT 2020 armv7l)
    Installed 3 months back give or take, working perfectly and have a site currently published – NGinx v2.7.2

    Raspberry Pi 3B+ – Pi OS Lite (Linux raspberrypi 5.10.17-v7+ #1403 SMP Mon Feb 22 11:29:51 GMT 2021 armv7)
    Installed today – Nginx v2.8.1 – On the browser page I get “Bad Gateway”.

    In the putty session, it says NGinx on a start after a stop “starting” and then 24 min later “Up 24 minutes (unhealthy)” and never changes to health.

    I have rebooted the Pi, stopped Nginx container, and started it and nothing helped. Also, to add everything is full patched.

    Thanks in advance.

    1. WunderTech

      Just responded to your other message. Hoping that fixes it!

      1. Wayne

        So I can confirm this is working now, thanks to both @WunderTech and @Plan945.

        Amazing product and very happy with advise and help!

  22. Plan945

    For all those who are getting the error

    connect ECONNREFUSED x.x.x.x:3306

    The latest image for MariaDB does not support 32bit dates. 99% of us are using 32bit OS. You can tell if you have a 32bit OS is by looking at the nginx_db_1’s log. For example, from PtToast post –
    577634-03-01 11:22:38 0 [ERROR] This MySQL server doesn’t support dates later than 2038,
    ^^^^^^^ – The year here is 577634. 😀

    I use the previous version 10.4.17 instead of the latest version 10.5.8. and it works fine.

    To fix, edit this line in docker-compose.yml
    image: ‘yobasystems/alpine-mariadb:latest’
    to be
    image: ‘yobasystems/alpine-mariadb:10.4.17-arm32v7’

    1. WunderTech

      This is amazing feedback because I haven’t been able to replicate it on my side and a ton of people are having the issue. I will update the tutorial with this. Seriously, thanks so much!

    I am having the same issue as abcdturix, connect ECONNREFUSED 172.18.0.2:3306..

    Because that log is basically useless, i have added the log from the db which seems odd. It keeps running through the same steps. I have tried a fresh image, and i copied everything from the tutorial.

    Ports 80 and 443 report open, no odd errors on install

    Any ideas would be helpful because im going mad, thank you

      I am trying to isolate exactly what could be happening since a lot of people are running into this and I can’t reproduce it. What OS are you running this on?

  25. abcdturix

    Hello.

    I have followed all the steps you indicate and have created the files using c & p. I get the same errors Eduard comments.

    Bad Gateway on login pge and in Portainer, nginx_app_1 it’s unhealthy and the log it says “connect ECONNREFUSED 172.18.0.2:3306” on logs

    1. WunderTech

      Are you using a wired connection or a Wi-Fi connection? A lot of people have been having this problem and I unfortunately can’t replicate it on my side.

      1. abcdturix

        wired. The Rpi is connected directly to the router.

        1. WunderTech

          Sorry for the additional question, but what operating system are you running?

  26. Eduard

    Hello WunderTech, I followed the instructions. Unfortunately I get an error on the INGX login page Bad Gateway and in Portainer nginx_app_1 unhealthy, connect ECONNREFUSED 172.18.0.2:3306 Please help!

    1. WunderTech

      We need to try and get the container reporting healthy to get this to work. Did you create the config file and is it shown exactly as it is on the site?

        1. WunderTech

          Solution was just posted in the article (in red). Can you try and see if that works?

  27. Giuseppe

    Hello,

    I have the same error as Anton

    “nginx_app_1 shows unhealthy because of the error “parse error: Invalid numeric literal at line 1, column 7 NOT OK”. In the logs I can see this error:

    error connect ECONNREFUSED 127.0.0.1:3306”

    I’m using a fresh raspbian on a Raspberry 4 as well. The DB is running properly and the firewall is OFF.
    Any suggestions?

    Thank you in advance!

    1. WunderTech

      Can you confirm that the config file is exactly as shown on the site? Anything different between yours and mine?

      1. Giuseppe

        Yes, I can confirm that the config file is exactly as shown on the site.

        1. WunderTech

          I will have to try and do some testing this weekend. A few people have reported issues lately, so something might have changed. I will try and test and let you know my outcome.

  28. Anton

    Hi!

    unfortunately my container nginx_app_1 shows unhealthy because of the error “parse error: Invalid numeric literal at line 1, column 7 NOT OK”. In the logs I can see this error:

    error connect ECONNREFUSED 127.0.0.1:3306

    I tried to follow some recommendations on github but nothing I tried solved the issue. When I try to login to Nginx I receive “Bad Gateway”.

    I run a fresh raspbian on a Raspberry 4. Do you have any suggestions?

    Thanks a lot

    1. WunderTech

      Are you using a firewall on your Raspberry Pi by any chance? Also, is the database properly running?

    Hi,
    I’m experiencing an “internal error” when I try to add the let’s encrypt ssl certificate on Nginx. I am able to add the proxy host just fine when I save only the host and it shows online on the proxy host page. However, if I choose the ssl certificate the internal error shows up. I’m not really sure what this error might mean and could really use some help. I did forward both ports 80 and 443 on my router and believe I have everything set up correctly. I’m a bit new to all this and have never used Nginx or docker before so I’m a bit unfamiliar with how they work. Also, I set up an A record on Cloudflare pointing to my public ip which is what I am using in Nginx. Is there something else I should change or add on Cloudflare to get this to work? My goal of using this is just to be able to access my jellyfin server remotely and securely. By the way, keep up the great work! Your videos are informative, clear, and easy to follow. Not to mention having a website with written instructions, a way to interact and ask questions is great and super helpful. Any help is greatly appreciated!

    1. WunderTech

      It sounds like you did everything properly. I think the first troubleshooting step will be to confirm that ports 80/443 are opened using a port checker.

      Can you use this website to test and confirm that ports 80 and 443 are both open? https://www.yougetsignal.com/tools/open-ports/

      1. Ashton

        I actually figured it out. You are right, the ports were forwarded but they weren’t open. On my router, the local IP address of my raspberry pi wasn’t being assigned. I think this had to do with a glitch in Xfinity’s software when I manually assigned a static IP to my raspberry pi a long time ago. To fix this I just had to factory reset my router and reconfigure it. Then the IP to the raspberry pi was properly assigned.
        Thanks for your help!

        1. WunderTech

          Glad to hear you got it working!

    Hey there,
    I installed portainer and also bitwarden with your tutorials and that worked fine.
    Now I want to install nginx and I get the following erro when I start “sudo docker-compose up -d

    Starting nginx_app_1 …
    nginx_db_1 is up-to-date
    Starting nginx_app_1 … error

    ERROR: for nginx_app_1 Cannot start service app: driver failed programming external connectivity on endpoint nginx_app_1 (fd5f46de26be0be172e2b30fe4ffb0899886183b633cca03a9ab9e37a50fdfc1): Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use

    In portainer I have the “nginx_db_1” running, “nginx_app_1” is only created.
    How can I fix that?

    1. WunderTech

      It looks like you’re using port 80 for something on your Raspberry Pi. If you are, you will be better off changing that port on that container so you can use 80/443 for NPM.

  31. Lutz

    Hi, thanks for the great tutorial for an absolute newby. I follow it and the installation went all the way without problems. But no I’ve got the same problem that was reported by Mohammed a couple of weeks ago: NPM remains “unhealthy” and as such login isn’t possible: Error “Bad gateway” which is obvious.
    Any idea other than a full fresh install? It’s a Raspberry PI 3+ just to run Docker / NPM with Raspberry image

    1. WunderTech

      I know this is a stupid question but have you tried to reboot? This error can be so many different things that a reinstall is normally the easiest, but not necessarily only way to fix it.

    2. Mohammed

      Hey Lutz! Just a hint since I just made that mistake today on a Pi4. The other day my problem was that I used a Pi Zero W which has an unsupported arv6 CPU, so it kept doing that. Today I faced the same “unhealthy” issue along with the bad gateway (which I didn’t have before) because I accidentally changed the ‘db’ as a database name while I was changing the username/password in the config.json.
      Hope that helps!

      1. Lutz

        Hey Mohammed. Thanks for the tip but that does not appear to be the case here. I did a complete, fresh install right from the beginning exactly following all steps without changing anything. Problem still exists.
        It appears to be a problem when generating the dummy SSL certificate:

        >>>

        Lutz

        1. WunderTech

          When are you receiving the error? When you say dummy SSL certificate, what exactly do you mean?

          1. Lutz

            The error that can be seen above comes up as soon as the two nginx container start running. While the db is running fine the npm container is remains “unhealthy” with the above error message is written in the nginx container log file.
            As you can see in the above text blog it seems to me that the nginx container tries to generate an SSL certificate locally (as at this moment the host can’t be reached by LetsEncrypt from the outside through port 80.

            So he (nginx) seems to generate a local “dummy” key until nginx is able to generate a “true” certificate via LetsEncrypt.

            Thanks, Lutz

          2. Lutz

            I am getting the error while the container is starting. It remains in the “unhealthy” state and loops while “trying to install dummy keys”.
            I did an install on a PI3 using a 32-bit Ubunutu 20.04. LTS server image and everything worked fine.

          3. WunderTech

            What OS are you getting the error on? I only use Raspberry Pi OS, so I can’t comment on how other OS’s work. It sounds like you got it working though, which is great!

  32. Carmelo Jimenez

    HI, followed instructions. both containers for nginx are up, running and healthy. Browsing to page presents the familiar login banner.
    Enter admin@example.com and pass changeme. Seems to work but I get the same page back again and never reach a point to change. Any suggestions?

    1. WunderTech

      Have you tried restarting the container? Any other error messages? Anything in the docker logs?

  33. noaccess

    Hello,

    after step 4
    enter the command

    sudo usermod -aG docker pi

    and continue the process

  34. lichti

    Hello and thanks for this tutorial!
    Could you tell me, how i can put nginx to a different IP?
    I wanna install PiHole on my raspberry too, but the Ports 80 and 443 are already reserved for Nginx.
    PiHole should be locally installed, so a different IP for Nginx and the DB would be perfect.
    Maybe you can help me!
    Greets from Austria

    1. WunderTech

      It might be smarter to change the port for Pi-hole (if you can). Since most domains use 80/443, if you use a different port for Nginx, you will have to append that port to every domain name. If you use 443, you will only have to type in the domain name.

      1. lichti

        Hmm.. But is it also possible to put nginx in a macvlan Network?

        1. WunderTech

          Yes, you can use a macvlan network for NPM.

          1. lichti

            Could you help me with that?
            Is there a way to let NPM only connect to the db and dont expose the Ports to public?

  35. Jerome

    Hi there, I have an observation to share but first let me tell you HOW GRATEFUL I am for your tutorials! I have zero knowledge about coding or web stuff things, but you made it simple. I followed the Raspberry, the Docker, the Guacamole tutorials and now here I am with a fully functional Nginx and able to access to my desktop over the internet :). I’ve read your “About” page, and I can assure you that your goal is fully reached!

    Back to my observation (I’m a pragmatic person) : I didn’t managed to make Nginx work with your files, the “nginx_app_1” container was unhealthy with a “parse error: Invalid numeric literal at line 1, column 7 NOT OK” message.

    Maybe it has to do with the fact I adapted your tutorials for my computer running on Ubuntu (wanna try before buying a raspberry), but long story short I managed to make it work with the “docker-compose.yml” from the Nginx website (https://nginxproxymanager.com/setup/). With this, no need for a conf.json and it’s perfectly working. I’ll give another try to your configuration when I’ll get a Raspberry, I’ll let you know if there’s a difference. Won’t be before a while probably, until then stay safe and keep going with your great and helpful work!

    Best,
    Jerome

    1. WunderTech

      A lot of people have been getting that error, so when I get some time, I have to go back and ensure that this still works like it used to. Either way, I’m glad to hear that you got it working and thanks for the feedback!

      1. Jerome

        Hi there!
        Small update to inform you that your method works perfectly on a Raspberry Pi 4!

        Cheers!

        1. WunderTech

          Awesome, thanks so much for letting me know!

        2. Lutz

          Hi Jerome. I have tried to install on a PI 4 and failed. Can you tell me which OS you are using? And a question from a complete Linux newby: do I have to do the installation as root (su)?

  36. David

    hi great guide but I’m having a problem is it go to my modem login page if I type in my public IP address and port 80 eg 123.123.123.123:80 i have port forward both ports and tryed two diff modems but it always go to my login page what im i doing wrong.

    1. WunderTech

      Did you properly open ports 80/443? Can you check an online port checker to confirm that they’re open?

      1. David

        yes checked both open checked with two sites.

        1. WunderTech

          What is the reverse proxy that you set up? Is it pointing to your router by any chance?

          1. David

            No to the pi4 itself modem/router ip 192.168.0.1 pi 192.168.0.4
            Posted about this on my isp Webb page and another person that has not got Nginx or a pi tried his public IP and port 80 and he also opens the modems login page isp are looking into this I just tried installing nextcloud and when I click on the site I made it take me to the modems login page.

          2. WunderTech

            Sounds like your ISP is blocking it then, unfortunately. Can you log in to the account and see if you can allow port 80 traffic?

        1. WunderTech

          I’m sorry, it’s hard for me to help troubleshoot with this information. I would try and reinstall Raspberry Pi OS, start from scratch and see if everything works as expected.

          1. Kenneth

            I start over with a new Pi and new card from scratch and got everything running except I got ‘internal error’ when requesting SSL from Lets Encrypt.
            Found out my domain provider which is name.com doesn’t support DDNS. Is there an work around? or it simply won’t work?
            I’m using DDNS feature offered by Asus Router WebUI, which also offer SSL. I can connect to BitWarden from WAN over 8080 port but no HTTPS available. Do I just simply change it to 443? If I later need Pi-hole and other services how do I go about other SSL requirement?

          2. WunderTech

            Did you port forward ports 80/443 to your Raspberry Pi? Are you using a firewall that could be blocking those ports? As long as you can communicate over that port, you should be able to get an SSL certificate (assuming the domain provider is setup correctly).

    2. David

      Hi Kenneth, have you found the solution to your problem with the message ‘No password auth for user’ ? I’ve been browsing the internet for a few days and I can’t find a solution. Thank you.

  39. Kenneth

    Thanks for the great tutorial. However I’m getting “no password auth for user” at nginx proxy manager log-in page it either doesn’t like the ‘changeme’ password or it’s not connected to database. This is another fresh installed Pi OS and everything appeared to be done correctly without errors. Only thing is that I can’t get nginx_db_1 container to become ‘healthy’ instead of ‘running’ in green color.
    In fact this is the 4th writeup I’m following and after hundreds of hours of failure I am so discouraged that I can’t even get one thing to work I had great success on Windows had been asking myself why fix things ain’t broke.

    1. WunderTech

      It’s reporting as healthy or running? It should be running when the nginx proxy manager container is running. Also, you’re able to get to the web admin console, it just doesn’t let you login?

      1. Bart

        Same issue here, portainer reports nginx_app_1 as healthy and nginx_db_1 as running and i can’t login to proxymanager 🙁

        1. WunderTech

          Someone posted a solution here a few days ago in the comments. Do you think you can try that?

  40. Wesley

    Getting the following Error on the nginx app container:
    Can’t take lock to run migrations: Migration table is already locked
    If you are sure migrations are not running you can release the lock manually by deleting all the rows = require(migrations lock table: migrations_lock

    1. Wesley

      Okay, so I connected to the db container and deleted the lock, but now it’s having errors migrating. with a table already existing

      1. WunderTech

        When you say you connected to the db container, what exactly do you mean? Can you also clarify what you mean when it says that a table already exists? Is that a database error and if so, where are you receiving it?

        1. Justin

          I also had this problem. In addition to deleting all rows in table migrations_lock, I had to drop the auth and user tables as well. After restarting nginx_app_1 (I stopped it before messing with the db), it eventually changed to healthy.

          1. WunderTech

            Thanks so much for sharing!!

  41. Abhilesh

    Hey WunderTech,

    Thanks for the great tutorials! I am trying to setup a self-hosted Bitwarden on my RPi4 using your tutorials, however, I ran into some issues while setting up the Nginx reverse proxy server.
    Additional info – I do have a nextcloud instance along a plex server running on the same RPi and I’m using apache2 as the webserver. I believe the errors I’m running into are because the port 443 is already in use by apache2 and hence the docker compose command fails for me. Below are the error messages I ran into –

    ERROR: for nginx_app_1 Cannot start service app: driver failed programming external connectivity on endpoint nginx_app_1 (12497ebf7da4

    Any help in resolving these?

    1. WunderTech

      You are correct. Is there any way that you can map port 443 to something else, then use the reverse proxy to expose that service if you’d like?

  42. Mohamed

    Thanks for the tutorial – very helpful! I’m having a persistent problem with nginx, the nginx_app_1 is always reporting “unhealthy” even after waiting for so long and restarting the pi and the containers many times. Here’s what the log says:

    This block keeps repeating itself again and again with the same outcome. I have forwarded the ports 443 and 80 on TCP but this didn’t change anything and it was happening before and after I did that. Any suggestions?

    1. WunderTech

      That error appears like it’s on the setup, so unfortunately, opening ports 80/443 wouldn’t help. Are you running anything else on the Raspberry Pi that could be causing conflicts?

      1. Mohamed

        No. It’s a fresh install of Raspberry Pi OS (with desktop) and nothing else. I also checked if Apache2 exists since I heard it may cause that conflict but also it isn’t there. Any chance to get it working somehow or starting from scratch is the only option?

        1. WunderTech

          I don’t want to say it’s the only option but it’s an option. If you have nothing else running on the Pi, it might be the easiest option, but if you have other things running, it might be worth it to take the time and try and isolate the issue.

    Hi, so I get to the point of running sudo docker-compose up -d and I also watched your YT video on this and my terminal did not finish like yours did. See Printscreen screenshot > http://prntscr.com/xzvmha < this is where it reboots its self and if I keep going with the next steps, it shows no such container. Code below. I checked portainer and they are not there was well.
    pi@RasPi-Webserver:~/nginx $ sudo docker update –restart always nginx_app_1
    Error response from daemon: No such container: nginx_app_1
    pi@RasPi-Webserver:~/nginx $ sudo docker update –restart always nginx_db_1
    Error response from daemon: No such container: nginx_db_1
    pi@RasPi-Webserver:~/nginx $
    I couldn't find anything that sticks out in the syslog but also I'm not very advanced at Linux or Pi.
    Thank your help!

    1. Wyatt

      Please note I do have a WordPress running on this same Pi. Possible conflict with it and already having a MySQL set up?

      1. WunderTech

        That could very well be the issue, but I’m not positive since I’ve never seen that issue before. Are you using port 80/443 for WordPress? Do you have a different SD card that you can test with to see if the port conflict is the issue?

  44. revan

    Hi! wondering if its OK to leave the username, password as “npm” or do we have to change each value to be unique?

    1. WunderTech

      I left that as default for the tutorial, but you’re free to change it to whatever you’d like!

    1. WunderTech

      Yes, Docker is required to use Docker Compose. I apologize for not being clearer initially (I updated the post to reflect this). This was a follow up to my prior tutorial on how to install Docker/Portainer on a Raspberry Pi, which is why it’s not specifically stated here.

      Glad you were able to fix it.

  45. manfred

    Hi
    Yes I use let’s encrypt.
    By accident I discovered the reason today.
    On the private (windows10) laptop I used to configure the PI and the certificates I got the message ‘not secure’
    This morning I rebooted my work (windows10) laptop, and there the connection for this website was directly secure. I directly opened my private laptop, which was not rebooted since I installed the certificates and even after ctrl + F5 is was still ‘not secure’
    So then I stopped the chrome browser, and all the chrome processes on the private laptop. I restarted chrome and now the site was directly secure

    I had no idea for certificates there is also a kind of cache in the browser.

    sorry for the inconvenience, but the problem is solved.

    1. WunderTech

      Not a problem, glad to hear it’s resolved!

  46. Wayne

    the moderation is a pain is a pain, can you do something about it please? I nerver know if the post is live

    1. WunderTech

      Unfortunately, no. I get hit with tons and tons of spam and I’m actively trying to fix it. This is the only option I have right now. If you submitted your message, I received it, I just haven’t had a chance to look into it yet.

      I am currently researching your issue and I’m trying to find out anything that I can. Did you run the two commands from the last message? If so, what were the outputs?

  47. Johnny

    Hi Frank – thank you for the tutorial!

    Sorry just a few quick questions:
    1) I see on picture 11 it looks like NGINX has the ability to manage multiple proxies?
    2) I have 3 dongles attached to a 4 port usb hub attached to the raspberry. If the above is correct, I just need to get them working as Port 10001, 10002, 10003 etc… correct?

    Many thanks Frank, your help is greatly appreciated!!

    1. WunderTech

      Hello!

      1. Yes, you can use NPM to manage multiple proxies. You would basically apply a different domain name (generally, by service is best, so plex.yourdomain.com, jellyfin.yourdomain.com, etc), and that will allow you to manage as many services as you’d like.
      2. When you say dongles, what exactly do you mean? Ethernet dongles? If so, your services would each be assigned a different network port and you will have to assign the proxy host to the correct port.

      Hope this helps, but if I can answer anything else, please let me know!

  48. Manfred

    Hi great tutorial, thnx

    I ran in some issues with latest docker version (5:20) not working on pi 4, but finally managed to install docker 5:19.03.14
    – I have pointed my dns to my IP-address. eg. demo.mydomain.com
    – my router is unifi mgt software running on the same pi (not in docker yet) and I created an forward rule to the ipaddress of the pi
    where nginx is running in docker
    – in nginx manager I created an host for demo.mydomain.com and set up this settings:
    * Scheme: http
    * ipaddress: the local 192.16.xxx.xxx address of the server
    * port: the correct port the server is listening
    * In the SSL tab force SSL

    When I use the addres https://demo.mydomain.com I am NOT redirected to the correct server in my network, but see this message:
    “Bad Request This combination of host and port requires TLS.”
    I also get in the chrome url “not secure”, but when I click on this I can see it us showing the lets encrypt certificate.

    Now I change the scheme in NGINX manager to HTTPS and now the site is working, but it still shows “not secure”

    What did I do wrong, or what did I miss?

    thanx Manfred

    1. WunderTech

      Did you request an SSL certificate from Let’s Encrypt? If you did, is it properly applied to the proxy host?

    2. Wayne

      The installs work fine, the issue is when I have to run “sudo docker-compose up -d”, there python errors, see above (1 Jan). I just dont get it. Your scipt at least runs, other tutorials I ahve used just fail stright up.

  49. Wayne

    what OS my I use, i get the impression it maybe related. tried 5 times now…

    1. WunderTech

      I use the Raspberry Pi OS Lite operating system normally (previously Raspbian Lite). What OS are you using?

      1. Wayne

        same, I dont know what to do. I do notice alot of API errors,

        Error while fetching server API version: (‘Connection aborted.’, FileNotFoundError(2, ‘No such file or directory’))

        1. WunderTech

          Have you tried with a fresh install of Raspberry Pi OS?

          1. Wayne

            Still no joy, same as above. Im using Raspberry Pi Lite (installing with Raspberry Pi Image) and it still gives me the same error. I kind of feel like the OS is missing componnents. What OS and what services should be installed other than the suggested,

            libffi-dev libssl-dev
            python3 python3-pip
            docker-compose

          2. WunderTech

            From what I’m finding online, it’s a docker issue. If you type both commands below, what are the outputs? You might have to either upgrade or downgrade docker.

            which docker
            docker version

          3. Wayne

            Python 3.7.3 (default, Jul 25 2020, 13:03:44)

  50. Wayne

    Please help, Im getting this error when I run the “sudo docker-compose up -d” and I have rebuild the image twice now with “RaspberryPi OS Lite” and both times I get the same error. Im guessing its the OS?

    All code was copied and pasted and nothing failed up till this point.

      That’s certainly a bunch of strange errors. Did the initial libraries and Docker Compose install properly? Any weird errors when you installed them? Is the config.json and docker-compose.yml file in the ~/nginx folder?

        1. WunderTech

          Can you try a different docker-compose file to see if it works? It’s hard for me to troubleshoot this specific issue as you’re getting generic errors that don’t have much information. As long as the docker-compose file and the database file are in the same folder, docker-compose should work. The error you’re getting is specifically stating that it can’t find the docker compose file or the config.json file.

          Let me know any other information that you can provide!

  51. David

    Hi, Thanks for all your tutorials so far. It has been a real good help and fun! I am pretty new at this.
    I have a question. I have one raspberry pi and have installed Nginx and it works perfectly thanks to your video. Now I would like to add a Pi-Hole container next to it. I couldn’t figure this out because it shares the same port 80. I searched the internet but I couldn’t find a clear solution. Some say you need to make use of the reverse proxy, but I don’t know how that works. Do you have any idea?

    1. WunderTech

      Thank you! You can certainly do this, but you will have to change port 80 to be something else. It is true that by default, they both use port 80, but changing port 80 and navigating to the management console using that port (8080 for example – http://IP_ADDRESS:8080) will avoid the port conflict entirely.

      Another option is to use a macvlan network interface. You can follow these instructions and everything should work properly! https://www.wundertech.net/how-to-set-up-pi-hole-on-openmediavault/

      Let me know if you have any questions!

  52. DavidP

    I have a couple of questions if I may, and this is coming from a reverse proxy noob…..
    1) can I setup a proxy host to a subfolder and if so how?
    example, nginx has ports serverip:80,81,443 but on the same server I have apache2 running on ports serverip:18080,18443 and I want to redirect serverip:443 to serverip:18443/subfolder
    2) How do I change access list for any of the hosts so they require authentication rather than publicly accessible?

    1. WunderTech

      The reverse proxy is only used for exposing internal services to the external internet. You can limit them by using access lists (like you mentioned), but they will still be exposed outside of your network.

      You cannot create a proxy host for a sub folder unless there is some sort of a web server in front of it exposing that specific folder. Think of a reverse proxy as a way to manage connections from outside clients to internal web servers. The service that you’re trying to access has to have a website that can be accessed inside of your local network. When you create the reverse proxy, you are then exposing that internal website to the outside internet.

      Hopefully this helps, but let me know if you have any other questions!

  53. WunderTech

    Have you tried to install a new instance of Raspberry Pi OS and go from there? It appears that the full re-installation of Docker will fix this, but since I’m not experiencing the issue, it’s hard to troubleshoot the exact command that could it fix it myself.

    Let me know and we can continue troubleshooting!

  54. Rob

    Hi, can’t get this working. Getting the same errors as @baggy when running the sudo docker-compose up -d command. Running the command from the nginx directory, and both files have been created with the correct syntax exactly as in the tutorial. Wondered if you could provide any help please, i’m baffled.

      By any chance, would you be able to set up a new instance of Raspberry Pi OS and try again? If you have other things configured on your Raspberry Pi, don’t worry about trying it, but if you’re using this for Nginx Proxy Manager exclusively, I know that reinstalling Raspberry Pi OS fixed it for other people.

      Let me know if you can’t do that and I will see if I can try and replicate the issue!

      1. Ebba

        Hi, I have this same problem and I’m not able to set up a new instance of Raspberry Pi OS. Any new ideas of what might be wrong?

        1. Steve

          I had the exact same error as you. The issue was that I hadn’t installed Docker… I thought it would be installed with docker-compose (I have never used Docker before, probably obvious to regular users that you need to install Docker itself first). I followed these instructions to install Docker https://docs.docker.com/engine/install/ and now it’s working properly.

      Did you port forward ports 80/443 to the Nginx Proxy Manager server? Generally, those are the reasons why the Let’s Encrypt portion doesn’t work.

      Let me know and we can continue troubleshooting!

    Hi,

    I posted a message / error last night when I was trying to “sudo docker-compose up -d” – but the message has now vanished? Anyway, I blew away my config and started again and it seemed to work ok this time?

    Hi,

    Not sure what I have done wrong, but “sudo docker-compose up -d” is not working, any ideas? Thank you in advance.

    1. WunderTech

      Are you running the command from the same folder where the docker-compose file is? If you’re not, try that out and it should work!

      Let me know and we can continue troubleshooting if necessary!

      1. baggy

        Thanks so much for getting back to me, Sorry for posting the second message! As soon as I did, this appeared along with your reply.

        1. WunderTech

          Not a problem! Glad to hear that it worked. If you need anything else, please let me know!

  58. trambo

    Very nice tutorials. I’m very thankful 🙂 I have set up my pi 4 with docker and followed all you steps. Everything seems fine until I try to add proxy host in nginx. Status says offline with a red dot. Can’t get it to go online.

    Command failed: /usr/sbin/nginx -t -g “error_log off;”
    nginx: [emerg] BIO_new_file(“/etc/letsencrypt/live/npm-2/fullchain.pem”) failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen(‘/etc/letsencrypt/live/npm-2/fullchain.pem’,’r’) error:2006D080:BIO routines:BIO_new_file:no such file)
    nginx: configuration file /etc/nginx/nginx.conf test failed

    Do you have any ideas why this is? Thanks!

    1. WunderTech

      Thanks for checking out the tutorial!

      When you say it’s offline, do you mean in the proxy hosts list? If so, it would appear like Nginx Proxy Manager cannot find the server that you specified. Are you using the IP address or hostname? If you are using the hostname, please try with the IP address.

      Let me know how it goes and we can continue troubleshooting!

      1. trambo

        Thanks for the reply. I actually wiped my pi and did fresh docker install so can’t say what the problem was anymore. This time everything runs great. nginx works and all proxy hosts are online and green. However It’s impossible to connect to any container over https. I got the certificate working but browser says host down. It’s the same with both IP and hostname. http works great. Guessing this is a docker problem now? I followed your docker install guide and installed three containers. portainer, nginx and airsonics but I can’t connect to any of them over https. Only http

        1. WunderTech

          Glad to hear you were able to get it (mostly) working!

          So the containers are on the same Raspberry Pi? Can you check what type of network you’re using for them? Generally, the only way that containers can communicate with each other is if you’re using a bridge network. You might already be using that, so let me know if you are and we can continue troubleshooting!

          1. trambo

            Yes. All containers are on the same Pi and containers are using bridge network. I don’t understand this. I’ve tried adding a bunch of new containers and I can’t connect to https on any of them. Not even on my local network.

          2. WunderTech

            It’s certainly a strange issue. When you say that it’s not working, can you use HTTPS to access them in a web browser? To clarify, certain web applications don’t have HTTPS out of the box, or they might even use a different port for HTTPS. If you can access them via HTTPS in a web browser, I’d need to do a little more research on why it’s not working with NPM. If they don’t work in a web browser, then the first step would be to get them to work with a web browser and then try NPM.

            Let me know and we can continue troubleshooting!

          3. trambo

            Strange indeed. So if i attempt to access portainer in my browser for example on my local network 192.168.1.x:9000 it’s fine but when i put https:// in front it can’t connect to it at all. All containers are the same.
            When I set up my reverse proxy using my domain (using cloudflare with A record to IP and CNAME for sub domain) in nginx everything is fine I get the cert but when I redirect to SSL cloudflare tells me host is down. I do get the green lock with a valid cert from let’s encrypt so nginx and cloudflare should be configured correctly just that my local https is just not there…

            Sorry to bother you. Your tutorial is perfect. My problem seems to be something else. Cheers!

          4. WunderTech

            Not a bother at all! This does make sense as not all web applications have HTTPS configurations by default. Some have both, HTTP/HTTPS but use different ports for each. I wouldn’t go crazy trying to encrypt the local traffic as the external traffic (that NPM/Cloudflare is managing for you) is using SSL which is the important part. Certainly doesn’t hurt to try and get it working internally but it’s not as important.

            Good luck and if I can answer any other questions, please let me know! Thanks for checking out the tutorial!

  59. Keith

    So I got everything working until I tried logging into the Nginx Reversee Proxy. The initial login and password is showing “No User auth available”. This was a clean install while I testing out the tutorial. Now really what the issue is as everything is showing healthy and working correctly. Also curious to know what the config.json is showing port 3306 but nothing is mentioned in the yml.

    1. WunderTech

      I haven’t run into that error myself. You are using the default credentials from the tutorial, right?

      As for 3306, that’s the port that is used for the database. You shouldn’t ever need to reference that port, but you will need to access the web admin portal of Nginx Proxy Manager using port 81.

      Let me know and we can continue troubleshooting!

  60. Domenick

    So I’m having an issue installing this on my Pi. My assumption here is that since I’m using this Pi as my Pi-hole, it’s also using port 80. Can these two programs exist with each other?

    I’m getting an error when it’s trying to create nginx_app_1 and the error states:
    ———————
    d225b9f0a): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use

    ERROR: for app Cannot start service app: driver failed programming external connectivity on endpoint nginx_app_1 (1fe0035bcd8b1c50f442a975033e2c33830da44098745b6390d8f69d225b9f0a): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use
    ERROR: Encountered errors while bringing up the project.
    ———————

    1. WunderTech

      You are correct – this is kind of a band-aid solution, but you can change Pi-hole’s admin port using the instructions below:

      Edit the lighttpd file (change the server.port to something other than 80) and restart the service. This will break after updates to Pi-hole, but it’s a good short-term fix to get to the admin portal.

      sudo nano /etc/lighttpd/lighttpd.conf
      sudo service lighttpd restart

      Then, you can navigate to the address http://[RASPBERRYPI_IP]:[PORT]/admin

      Let me know if you have any questions! Thanks for checking out the tutorial!
