Hello, I'm new to using traefik and I'd like to understand why when I execute my docker compose I access my n8n instance via my domain but I can't access prometheus or grafana. (Grafana and Promeheus works, but can't access them through my domain)

Thanks for help !

Add the target port of each target service in labels. See [simple Traefik example](https://github.com/bluepuma77/traefik-best-practice/tree/main/docker-traefik-dashboard-letsencrypt).

Add `docker.network` in labels (or central with provider) when using multiple Docker networks. Make sure the network name is fixed (`name:`), so compose does not create a prefix.

Enable and check Traefik debug log [(doc)](https://doc.traefik.io/traefik/observability/logs/#level).
