Hi, I've scoured pretty much every traefik forum/stackoverflow/reddit post relating to bad gateway issues but still stumped. I'm trying to get seafile running in a docker container, I've got the traefik dashboard up and running but when I visit [seafile.example.com](http://seafile.example.com) I get a blank page with "Bad Gateway" in the corner.

From what I've read I think it is a network/port related issue with Traefik not being able to properly reach the service - but not quite sure how to diagnose this? This is probably down to me not understanding routers/services properly but any pointers would be much appreciated.

My docker-compose.yml is as follows:

```auto
version: '3.0'

networks:
  web:
    external: true
  internal:
    external: false
  seafile-net:

services:
  db:
    image: mariadb:10.5
    container_name: seafile-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_LOG_CONSOLE=true
    volumes:
      - /opt/seafile-mysql/db:/var/lib/mysql # Requested, specifies the path to MySQL data persistent store.
    networks:
      - seafile-net
      - internal
    labels:
      - traefik.enable=false

  memcached:
    image: memcached:1.5.6
    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      - seafile-net
      - internal
    labels:
      - traefix.enable=false

  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    volumes:
      - /opt/seafile-data:/shared  
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=password  
      - TIME_ZONE=Etc/UTC
      - SEAFILE_ADMIN_EMAIL=email@example.com

```

I've checked traefik dashboard and all the container logs and can't see any issues being reported. The labels were pulled from here [Help with traefik v2 labels? - Docker - Seafile Community Forum](https://forum.seafile.com/t/help-with-traefik-v2-labels/13868/)
