Pod can not reach any domain

@adlerspj Thanks for your reply.

I set up microk8s completely new, but i have still the same issue.

~$ kubectl exec -i -t dnsutils -- nslookup google.com
Server:         10.152.183.10
Address:        10.152.183.10#53

Non-authoritative answer:
Name:   google.com
Address: 216.58.212.142

~$ kubectl exec -i -t dnsutils2 -- nslookup google.com
;; connection timed out; no servers could be reached

command terminated with exit code 1

~$ kubectl get pods -n kube-system -l k8s-app=kube-dns -o wide
