I used the docker-compose file from the official github repo: https://github.com/LemmyNet/lemmy/blob/main/docker/docker-compose.yml

But after the comment from @marsara9@lemmy.world I changed it to pull the image from dockerhub instead of building it myself. Now it pulls correctly and the server comes online but is almost unusable. The homepage displays but I cannot login as admin or create a new user :/

Edit: Here is the docker-compose.yml I used

Edit 2: I think I found the issue why the server is unusable. I have websocket errors
