Checklist

• Have you pulled and found the error with jc21/nginx-proxy-manager:latest docker image? Yes
• Are you sure you're not using someone else's docker image? Yes
• If having problems with Lets Encrypt, have you made absolutely sure your site is accessible from outside of your network? N/A

Describe the bug

• A clear and concise description of what the bug is.
• What version of Nginx Proxy Manager is reported on the login page?

Upon standing up a new NPM instance i get a few warnings about database communication issues) but I can login. As soon as i tell the stack to stop and then start it again, the database starts fine but the app container fails to start. (see screenshot)

To Reproduce Steps to reproduce the behavior: Deploy latest version using docker stack in example. Once everything is running fine, stop the stack and then start it again.

Expected behavior The app container should be able to be re-created pointing to the same volumes and function properly

Screenshots App container:

Database container:

Operating System Using centos 7 with docker swarm on top. I am also using Storidge for the storage plugin.

Additional context Add any other context about the problem here, docker version, browser version if applicable to the problem. Too much info is better than too little.

The only way I can get it to be fixed is to delete everything about the stack and have it re-create.

Could I be missing a volume mount?

I messed around some more and sometimes the container starts successfully and some times it doesnt...

[damntourists]

I am also encountering this issue while trying to run this on a swarm of raspberry pi 4's.

[pixel3design-hub]

I am also encountering this issue while trying to run this on a swarm of raspberry pi 4's.

Same here. Using Docker Swarm in Portainer on a RPi4-4GB

[NozomiKimot]

I am in the same boat, starting up a fresh instance is completely fine but any following startup attempts of the container falls flat on its face and recreating the entire instance with a blank slate is the only way to get it running again, super frustrating!

[NozomiKimot]

Although upon further testing I'm not entirely sure I'm encountering the exact same problem I only started encountering the issue today and the only thing I had changed was changing some hosts to start using DNS challenges for the SSL certificates. I removed those entries from my database and it starts up fine again So, for me at least, my failed startup issues are related to using DNS challenges for my SSL certs Not sure if DNS provider for the challenges make a difference but I use Cloudflare

[cestnickell]

Same issue here, I'm also on an RPi4 using DNS challenge (Cloudflare) for my SSL certs.

[wieluk]

Same Issue for me on boot up this happens but if I manually restart afterwards I don't have any problems

[ggantn]

Same issue for me I cannot create the container on my raspberry pi4

[0x5ECF4ULT]

Same issue. 4x RPi 4B Swarm Deployment using Portainer This issue does not arise if the stack is started via docker-compose. Very weird... I dug into the code a little bit and it seems this issue is related to the supervisor on http://127.0.0.1:3000/. At least this is what my logs are saying. I think the timing is kind of screwed. The container crashes after the JWT keys are generated and NGINX is restarted. My theory is that the supervisor service on http://127.0.0.1:3000/ is not running yet when restarting NGINX and that causes s6 to panic. But why would it work when starting the stack via compose then?

[0x5ECF4ULT]

Okay let me clear up my nonsense: The error log indicates that the service on http://127.0.0.1:3000/ is not available... this has nothing to do with s6, however I've found this which means if the frontend terminates, the s6 service in /var/run/s6/services is also terminated which causes s6 to panic. @jc21 could you please take a look at this? I'm by no means a professional user of s6 and could just talk bs. Hope my theory helps tho!

[Riiskyy]

I am having this issue when trying to run in a single node RPi swam even when deploying using compose

[MaleNurse]

Occurs for me as well, as varying points in the startup. RaspPi4 as a manager in a swarm, with the stack running through Portainer. Pulled 2.7.3 instead of latest (no other changes to the compose) and it's running fine.

ETA: nevermind. After one reboot it decided that it didn't want to start again. That version must be happy only w/ an empty config and DB.

[serenewaffles]

Has anyone found a workaround for this?

[oMadMartigaNo]

Same issue for me RPi4x2 (Ubuntu 20.10 x64) swarm and running npm through Portainer v2.1.1.

Hello, my instance wasn't working. I cannot say for sure, but as soon as I truncated the audit_log on the database it started working again!

Hi! Thanks for the recommendation, unfortunately it did not solve my problem. s6-svscanctl: fatal: unable to control /var/run/s6/services: supervisor not listening

[oMadMartigaNo]

I think this fix my issue?! 🤔 image: 'jc21/nginx-proxy-manager:github-pr-975'

Update: Nevermind... 😞

[ljpaff]

Any progress with this issue? I have same issue running on rpi 4 with docker-ce

[sebabordon]

Hello, trying to debug this issue, I've found that truncating the certificate table on the DB finally allowed NPM to start. I had several duplicate certificates from my history from a version that had timeouts. Now I'm in the process of renewing all certificates (and purging old proxy hosts). So far So good

[Kegelcizer]

Same issue as OP when stopping the stack. Debian 10 and using sqlite.

I had to delete everything from the two volumes and reconfigure from scratch.

[julesrulez96]

Hello, also trying to find the bug for this issue. I have a docker-stack deployed on rpi 3b+ ubuntu x 64, when starting clean means no data (db, etc) is there for the containers to start, everything works fine, but deploying the compose file as an stack (service) the nginx proxy manager runs into this issue, the db gets the communications packets error and the proxy manager the supervisor is not listening error. also have tried the sqlite solution, same problem.

Are there any solutions yet?

[Rihan9]

Hello, I have the same issue. Currently, the only thing I can do is to set it to restart itself in case of an error and watch its build dozens of junk containers before starting. Could it be an execution order problem?

[pvd-nerd]

Experiencing the same issue on 2.9.3 & 2.9.4 w/ 4 RPi4 8GB swarm. Was previously working, restarted the docker cluster and it won't come back up. Tried completely new stacks, sometimes it will start if you just keep letting it retry.

[comdr-chocchip]

Yeah same issue here. was trying to figure out why i was getting bad gateway error at the login page, my logs look the same

[abhinav-TB]

I had the same issue, it is working fine when I started the container again, but I would like the team to look into a permanent solution so that it does not go down on crucial times

[luandro]

Getting this when running offline on a Rasp 4.

[vdiogo]

Same issue when running the "Check Home Assistant configuration"

[tablatronix]

Anyone know what this issue is? Same here, was working, now wont, same error

[Kegelcizer]

I still have this issue with 2.9.13-18. Reverted back to 2.9.12 since it's the latest version that works for me.
