Kubernetes Unable to connect to the server: EOF

[shenyongo]

Earlier today I had increased my Docker desktop resources, but when ever since it restarted Kubernetes has not been able to complete its startup. Whenever I try to run a kubectl command, I get Unable to connect to the server: EOF in response.

I had thought that it started because I hadn’t deleting a helm chart before adjusting the resource values in Settings, thus said resources having been assigned to the pods instead of the Kubernetes api server. But I have not been able to fix this issue.

This is what I have tried thus far:

• Restarting Docker again
• Reset Kubernetes
• Reset Docker to factory settings
• Deleting the VM in hyper-v and restarting Docker
• Uninstalling and reinstalling Docker Desktop
• Deleting the pki folder and restart Docker
• Set the Environment Variable for KUBECONFIG
• Deleting .kube/config and restart
• Another clean reinstall of Docker Desktop

But Kubernetes does not complete its startup, so I still get Unable to connect to the server: EOF in response.

Is there anything I haven’t tried yet?

I’m also encountering this error…
az login is OK.
az aks get-credentials is OK.

but when I tried to kubectl get nodes or pods it returns me same error: Unable to connect to the server: EOF
