Hi there,

I am new on GKE autopilot, I have created the cluster for POC purposes. Suddenly my cluster is down no nodes are in a ready state. When I checked logs I am getting the below error.

1709 pod_workers.go:951] “Error syncing pod, skipping” err=“network is not ready: container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: cni plugin not initialized” pod=“kube-system/node-local-dns-nfj9n” podUID=08a3fcd5-45b6-4ac6-b02d-22ed5bffa407"

And when I am trying to apply CNI Plugin then I am not able to do due to permission reasons.

If anyone has a solution or reference document then please help me to resolve this issue.
