Unable to list nodes from EC2-VM - couldn't get current server API group list: Get "https://20C65533F05DF3F9E67678DDF25B032.gr7.us-east-1.eks.amazonaws.com/api?timeout=32s

Hi - I have created the AWS EKS-Cluster with 2 worker nodes. I have another EC2 instance acting as a client VM to access the above cluster. I assigned all the roles correct.

I'm getting the below error when I tried to access the EKS-cluster using kubectl command kubectl get nodes **couldn't get current server API group list: Get **"https://20C65533F05DF3F9E67678DDF25B032.gr7.us-east-1.eks.amazonaws.com/api?timeout=32s

Please suggest.
