[BUG] Unable to resolve host address

[YAOHAO9]

What did you do

• How was the cluster created?

  • autok3s create --provider k3d --master 1 --name K3D --worker 2 --api-port 0.0.0.0:0 --image docker.io/rancher/k3s:latest --ports '81:80' --ports '6443:6443'

• What did you do afterwards?

Here are the steps to reproduce it

• docker exec -it k3d-K3D-server-0 sh Enter one of the k3s nodes.
• crictl ps List the containers of the node that you enter
• crictl exec -it container_id sh Enter a pod which is on the node you have entered.
• wget google.com you will get this error: "wget: unable to resolve host address 'google.com'",
• If one of the pods cannot resolve the DNS issue, It means all of pods in the node cannot resolve DNS issue. But it is strange that there is no problem with the DNS issue of the node where this pod is located

Assuming this is on v5.7.0, this was fixed in v5.7.1 - please reopen, if it wasn't fixed with the new release for you.
Please see #1462

EDIT: adding to your observations: the error is in CoreDNS, which is not used from the pods but not from the node
