Hey, i try to import an fresh created 3 node control-plane,etcd,master v1.26.12+rke2r1 cluster to an rancher singel host docker container instance. the problem is that the cattle-cluster-agent cant get the ip of the public domain of the singel host rancher. The domain is public available and the dns of the nodes are working too. Any idea how i can fix that? I created a "test pod" for testing dns stuff.

apiVersion: v1
kind: Pod
metadata:
  name: dns-debugger
  namespace: default
spec:
  containers:
  - name: dns-utils
    image: busybox
    command:
      - sleep
      - "3600"  # Der Container wird 1 Stunde lang laufen, um Zugang zu haben.
  restartPolicy: Never

root@NODE-0:~# kubectl exec -it dns-debugger -- nslookup google.de
;; connection timed out; no servers could be reached

command terminated with exit code 1
root@NODE-0:~# kubectl exec -it dns-debugger -- ping google.de
ping: bad address 'google.de'
command terminated with exit code 1
