Getting context deadline exceeded (Client.Timeout exceeded while awaiting headers);

I am getting below error in the cluster with Rancher 2.x and K8S. Any ideas on how to resolve?

This cluster is currently Unavailable ; areas that interact directly with it will not be available until the API is ready.
