Plex returns 502 Bad Gateway through Traefik

[Permanently]

When accessing Plex, it seems to pop out a 502 error. I tried figuring out where it came from, and my only hypothesis is that the plex hostname can't be reached from Traefik, hence the error to begin with.

Not managed to get it working once whilst using this, unfortunately. Not that Plex doesn't work (operates fine through direct IP), just that Traefik doesn't like the plex hostname for whatever reason.

Did you activate the VPN option for Plex in your config.yaml file ?
If so, the host would not be plex:32400 but gluetun:32400

On another note, can you try to access http://plex:32400/web/index.html instead of the webroot ?

VPN is not activated — in fact, it's still nearly the default configuration.

  - name: plex
    enabled: true
    vpn: false
    # uncomment to use custom file with specific parameters for hardware transcoding
    #customFile: plex-hardware-transcoding.yaml
    # You can also place you own file in services/custom/ and call it here like this:
    # customFile: custom/my_own_file.yaml
    traefik:
      enabled: true
      rules:
        - host: plex.${TRAEFIK_DOMAIN}
          httpAuth: false
          internalPort: 32400

Whether I try webroot or not is out of the question, as it's a bad address, so it'll fail either way. Regardless, I'll try for your satisfaction.

Maybe, for some reason, your traefik container and plex container are not in the same docker network (traefik-network).
Can you check that ?

Plex is on host, whilst Traefik is on traefik-network. However, this is intended.

seedbox/services/plex.yaml

Line 6 in f420227

network_mode: host

The point of this issue is, it's not reachable via hostname, whilst in the Traefik configuration the plex configuration is pointed at via hostname.

Hello!
In fact for a certain time Plex through Traefik does not work, I also have a 502 bad gateway.
It used to work, but I cannot remember since when it's been broken.

The "official" Plex way of accessing it it directly through port 32400 (and via opening port on your router if required).
Do you confirm it works by accessing the machine on port 32400 ? Or via app.plex.tv ?

Works through port 32400, and through app.plex.tv. Just, ideally it'd work through plex.${TRAEFIK_DOMAIN} as well. More of a satisfaction thing rather than a necessary requirement.
