Hi, We have deployed Rancher - 2.7.3 with k8s version 1.23.16 we are facing issue with coredns (connection timed out). pods are not able to resolve dns queries because they are not connecting to coredns address 10.42.0.10 (connection timed out).

kubectl exec -ti dnsutils -- nslookup kubernetes.default
;; connection timed out; no servers could be reached
command terminated with exit code 1

kubectl exec -ti dnsutils -- cat /etc/resolv.conf 
nameserver 10.43.0.10
search default.svc.cluster.local svc.cluster.local cluster.local COMPANY_DOMAIN_NAME
options ndots:5

Any thoughts on this?
