After upgrading EKS to 1.28 kubctl command giving The connection to the server was refused - did you specify the right host or port?

Question

HI,

After upgrade of EKS cluster from 1.24 to 1.28 we have noticed **The connection to the server was refused - did you specify the right host or port?**  error. But once in a while if keeps on trying it connect once and again seeing the same error.

Here is the command
kubectl get pods -n  --kubeconfig=

We are not able to find what is the rootcause for the issue, if anyone facing similar issue and had any workaround or resolution will be a great help.

Thanks & Regards,
Nag

Answer

If kubectl does not have the correct credentials to access the cluster, this issue may be encountered.
