→ Traefik dashboard and whoami is available,
But the address myserver.dns.net/nextcloud says:

" Not Found

The requested URL was not found on this server.

Apache/2.4.52 (Debian) Server at myserver.dns.net Port 80"

Can somebody help me to fix this issue?

I don’t have a specific answer for you but the use of paths in nextcloud (ie https://domain.com/nextcloud) has for years caused a lot of problems. I’m not sure why. The sane advice is to use a subdomain instead (ie https://nextcloud.domain.com or nc.domain.com or something similar).

Maybe it is as easy as: Configuration Parameters — Nextcloud latest Administration Manual latest documentation and Configuration Parameters — Nextcloud latest Administration Manual latest documentation in config.php (overwritewebroot and overwrite-cli-url ).

you config looks pretty good… I would recommend you enable traefik access log - then you can easily track where the request is routed (don’t provide a file and it will log to STDOUT by default and you can easily monitor logs real-life “docker logs traefik -f”).

The other issue - which not related to your problem - you must advise NC it’s run behind reverse proxy by adding OVERWRITE* parameters to config.php (docker ENV variables only work for very first container start)
