This morning I woke up and the radio was not playing. I soon figured out, that my DNS, AdGuard, was for some reason down.

I started with the debugging, even before I had breakfast. Not evan a coffee!

The docker-container for AdGuard was running and reported no error. So I dug deeper and deeper, just to find out, that several containers showed strange behavior. For example did Traefik had som error that it could not find the middlewares, that where configured via environment variables.
