Traefik Internal Server Error

Rancher Version: v2.6.8
Env: Bare-metal cluster

My Problem:
I am trying to access the traefik dashboard from the internet because rancher is running in the cloud. I created an Ingress entry the same way I created all the other Ingress entries for my services, but I only get an “Internal Server Error”. In the Log, traefik says Skipping service: no endpoints found. I have no Idea what went wrong.

Does anyone have an idea why it won’t work?
