Getting "gateway timeout" since updating Docker to latest (potential bug?)

Traefik Traefik v2

Thank you very much for your answer. You are right of course it makes it easier if I write the configuration here :smiley:

Here is my setup GitHub - Psycho0verload/traefik-crowdsec-stack
The only difference to the manual is that IPv6 is still included.

In my traefik.yml the network is defined:

And here is the configuration I use in the docker-compose.yml. At the top of the log it was Gitlab. So here is the configuration of Gitlab:

version: "3.9"

With the configuration also no network is created which I have not defined
