Original GitHub issue: https://github.com/chr0nzz/traefik-manager/issues/33

Traefik Manager version

1.0.0

How are you running Traefik Manager?

Docker

Traefik version

3.6.14

What happened?

I've been trying to move the traefik dashboard off of port 8080 as it conflicts with another service. I've changed the manager.yml file and the labels on the docker container but I am unable to connect to it on port 8085. I've disabled insecure api as traefik documents suggest you need to do that to change the port.

Steps to reproduce

changed ports in manager.yml and compose.yml

What did you expect to happen?

The api being available on 8085. I'm not sure if there's another place to change the port I missed or I am misreading the documentation.

Relevant logs or screenshots

This isn't a TM issue - it's how Docker port mapping works. 8085:8080 means your host machine can reach Traefik on port 8085, but inside the Docker network all containers still talk to the internal port (8080).

Change your manager.yml to:

traefik_api_url: http://traefik:8080

The 8085 port is only relevant if you're accessing the API from outside Docker (e.g. from your browser or a tool on the host). Container-to-container communication always uses the internal port regardless of what's mapped on the host.

Sorry, I'm pretty new to traefik and still learning the configs and wanted to make sure the manager.yml setting wasn't affecting it.

Thanks but I ended up just reverting to the original config with insecure api and put authelia on the dashboard domain.
