Nginx not delivering HTML on port 8081

mrlnbllmnn

Hello,

after upgrading to 2024-06 I noticed that the Admin Webgui is slow, missing the container information and ACME hangs on “Waiting for Nginx…”

I have narrowed down the issue to nginx not delivering content on port 8081, another installation without issues shows html opening and closing tags when using curl http://nginx:8081, while the affected system does not show anything and I have to close curl using Ctrl+C.
There seems to be some issue with dynmaps, nginx is listening on 8081 but using curl to test the urls from mailcow source code doesn’t get answers from nginx.
the dynmaps.conf mentions phpfpm:9001, but I am not sure what to test there and I don’t see any errors in the php-fpm container logs.

Any help on where to continue troubleshooting is highly appreciated.
Thanks and have a great day.

Greetings,
Marlon

Have you checked in your hosts /etc/resolv.conf if there is a search suffix? Remove it and test again.
There is a known error which should be fixed by release 2024-06b soon:
mailcow/mailcow-dockerized5928

Hell, I remember a terrible day when a search domain stopped mailcow from starting at all with a previous version…
So yes, I compared the two servers, my personal server had the search domain commented out. After commenting it out on the server with the issue, the certificates are currently being renewed.
Thanks a lot.
