Hello,

I'm using Traefik for the first time and have tried to install Traefik version 2.11. I also wanted to activate the dashboard to get a better overview. I can't get the dashboard to run on port 8080. Every time I try, I get the message that port 8080 is already in use. However, the port is free, as confirmed by both docker ps and netstat. I have now changed the port to 8081, and then I can access the dashboard. Now both entry points are displayed, even though 8080 is not configured. Before changing the port, I deleted all containers, ran a docker system prune, and restarted the VPS. Does anyone have an idea what I'm doing wrong?

enables Traefik dashboard on internal port 8080.

You map it to external container port 8081:

```auto
    ports:
      - 80:80
      - 443:443
      # -- (Optional) Enable Dashboard, don't do in production
      - 8081:8080

```

so it’s available at URL:

```auto
http://example.com:8081/dashboard/

```

You also create an internal Traefik `entrypoint` on port 8081, which has no effect on dashboard:

```auto
  custom:
    address: :8081

```

Check [simple Traefik example](https://github.com/bluepuma77/traefik-best-practice/tree/main/docker-traefik-dashboard-letsencrypt) how to access dashboard on regular https `entrypoint`.

* * *

Regarding used port 8080 on host, try:

```auto
docker run -p 8080:80 traefik/whoami

```

Thank you very much for your help.

The docker run command does not work as well. Same message, the port is already in use.  
And again I have checked docker ps and netstat. Both show no port assignment for 8080.

I dont get it where the port assignment is coming from. I will erase the VPS and try it again.

Thanks for your help!

Did you run `sudo netstat -tulpn`?
