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?
