Bad Gateway when running behind Traefik V2

  • Hello,


    I set up a test installation of Mailcow which works fine. Now, I want to move the installation behind a Traefik V2 proxy, however, I only get the words Bad Gateway when trying to access the web interface.


    I followed the installation guide in https://mailcow.github.io/mail…rized-docs/firststeps-rp/


    Code: mailcow.conf
    1. HTTP_PORT=8080
    2. HTTP_BIND=127.0.0.1
    3. HTTPS_PORT=8443
    4. HTTPS_BIND=127.0.0.1

    Other containers, e.g. the whoami "Hello World" container work fine with similar settings.


    `docker-compose logs` is not helpful, giving no messages at all when trying to access the web interface.


    What can be the problem here?


    Replies in German are also great!


    Thanks!
