Nginx, PHP-FPM, Traefik - Bad Gateway (504)

iam running docker on an openmediavault. so iam not able to expose port 80 and 443 for traefik on the same ip, cause this would end up ppl reaching my openmediavault gui from web. thats why i’ve done this in past.
It also worked but currently it won’t anymore, and i still dont know why. my Other containers (like teamspeak, gittea etc) still working and using the same networking method. it just affects this nxginx / php-fpm containers.

and if i need to communitcate between containers, i use the docker internal ips ofc.

edit1: I changed the ovm port now. iam using only docker internal for communicate and expose 80+443 on ovm host ip. But the issue persists. :frowning:
