Solution 2:[2]

One reason for this is the AKS cluster certificate getting rotated. See https://docs.microsoft.com/en-us/azure/aks/certificate-rotation.

As outlined there, run:

az aks get-credentials -g <RESOURCE_GROUP_NAME> -n <CLUSTER_NAME> --overwrite-existing

and see if it gives you an output like:

Merged "<CLUSTER_NAME>" as current context in /home/<USER>/.kube/config
