Setup information
docker-compose

Describe the bug

Site shows "Bad Gatway".

To reproduce
Basically just do docker compose up with the dockerfile. My traefik is pretty much a standard configuration and works for other webpages.

Expected behavior
I want to see the page and use traefik as the reverse proxy.
