Wordpress inside Docker with Traefik 2

Traefik Traefik v2
1

I followed these Examples to setup traefik on my server. I tried following some other guides to setup my Wordpress-Site inside docker and make it accessible through Traefik without the need of nginx.

Currently I have a whoami-Container running on whoami.mydomain.com, which works fine.
But accessing blog.mydomain.com only leads to a 502 Bad Gateway Could you tell if my error lies within the traefik-labels or if it is something wordpress related?

My Files look like this:
