I cannot access my k8s cluster - DO configs do not work

Posted on March 19, 2020

Hello, Today I’ve upgraded my cluster to the version: 1.16.6-do.2. Now I am not able to access my k8s cluster.

I downloaded config file from DO dashboard, I also tried to use doctl tool to configure my kubectl, but the response is always the same:

doctl kubernetes cluster kubeconfig save xyz Notice: Adding cluster credentials to kubeconfig file found in “/home/xxx/.kube/config” Notice: Setting current-context to do-fra1-xyz kubectl get nodes Unable to connect to the server: x509: certificate has expired or is not yet valid

Do you know how can get my connection back?

Hi,

Can you try completely deleting /home/xxx/.kube/config and then rerunning that doctl command? Sometimes stale data can hand around in that file. Removing it will ensure there is nothing but the fresh file contents generated in there.
