My config is:

services:
  traefik:
    image: traefik:v3.0
    ports:
      - 80:80
      - 443:443

networks:
  proxynet:
    name: proxynet
    external: true

volumes:
  letsencrypt:
    name: letsencrypt

when im trying to access the dashboard, the page loads but throws 404 errors for the following routes

I even did docker prune -a before trying to setup traefik again. In the logs I can see this:

Looks similar to simple Traefik example, I can’t spot the error yet.

The domain and sub-domain point to your Traefik IP?

Note that the rule logic is wrong, it should be:

Host() && ( PathP() || PathP() )

But it should still work with the current config.

Thank you for your reply. I found that the problem might not be what I originally thought it to be. The thing is, I can see other tabs other than the main one on the dashboard and see the services and so on. But when I use one of the other subdomains I have, it works just fine and dashboard loads with no problem. Then also I have this weird bug that when I run one of my other containers which has it's own router and other service, it somehow points to the traefik container and shows the dashboard with no bugs even though I don't want it. I'm dazed and confuzed

Make sure to get the router rule logic right and use different router names in labels for every service/container.
