Unable to see worker nodes

I have 3 worker nodes, I am able to login to them. But when I hit “kubectl get nodes” command - some time I can see the worker nodes visible but some time not. I am not sure what I need to check here to fix it. Can some one please help me out here ? Thanks in advance. !! Regards, Nagaraj

kubectl get nodes depends on the kubelet running on the nodes.

Is this a cluster you have deployed or one from the labs?

can you login to the worker nodes and check the kubelet logs?
