Hello @ptilloo,

Can you confirm the version of Traefik you are using?

If you are using Traefik v1.6.4, it is no longer supported or updated to keep current.

I would advise you look at using the latest stable version which is 2.4.9 (Release v2.4.9 · traefik/traefik · GitHub)

The kubernetes client that is in each of the Traefik versions only supports certain versions of Kubernetes API. It is likely that the old version in 1.6.4 just does not support K8s 1.18.
