I'm giving a try at Traefik Hub on Rancher Desktop
I have Rancher Desktop 1.4.1 on Linux (openSUSE Leap 15.3) with Kubernetes v1.24.1
Installation of the agent went well and the traefik hub agent seems to be running fine.
$ kubectl get pods --namespace hub-agent NAME READY STATUS RESTARTS AGE traefik-hub-6977c67669-9x5lb 1/1 Running 0 8m32s
On the agents page on traefik hub https://hub.traefik.io/agents the agent appears as pending (still after ~10min)
I checked that firewall is off
