Hello,
I encounter this error from time to time while trying to access my aks cluster located in "westeurope". Please could you let me know how to troubleshoot this?
Error: Kubernetes cluster unreachable: Get "https://aks-42c-platform-labs-eu-west-dns-e15d6df2.hcp.westeurope.azmk8s.io:443/version": dial tcp: lookup aks-42c-platform-labs-eu-west-dns-e15d6df2.hcp.westeurope.azmk8s.io on [fe80::424a:3ff:fe94:20bd%en4]:53: no such host
The cluster info is as follows:
Name Location ResourceGroup KubernetesVersion CurrentKubernetesVersion ProvisioningState Fqdn
------------------------- ---------- ------------------------- ------------------- -------------------------- ------------------- -------------------------------------------------------------------
42c-platform-labs-eu-west westeurope 42c-platform-labs-eu-west 1.22.11 1.22.11 Succeeded aks-42c-platform-labs-eu-west-dns-e15d6df2.hcp.westeurope.azmk8s.io
Feel free to let me know if any additional information is needed.
Many thanks.

If it is in Stopped state, start the cluster and wait for a couple of minutes for the cluster to come into a running state. Once it is in running state, use the kubectl commands through Azure Cloud Shell to connect to the AKS cluster as described in the document below:
https://learn.microsoft.com/en-us/azure/aks/learn/quick-kubernetes-deploy-cli#connect-to-the-cluster
Please try this and if you are still seeing any issues, let me know in the comments and I can further investigate.

2022-09-27T09:35:50.95+00:00 The cluster has been always in Running state (please check the cluster info from my original post), and the error happens occasionally.
If I retry after a few minutes, I can connect to the cluster successfully.
