sudo kubectl get nodes - The connection to the server localhost:8080 was refused about kubernetes

The /etc/kubernetes/admin.conf refers to the location on the first control plane node. You need to copy that file from the control plane node and put it in ~/.kube/config on the machine where you are running kubectl from.. If you do not want to copy it there, then copy it wherever else you'd like, then export KUBECONFIG=/wherever/else/you'd/like. Hopefully that works.

But there is no /etc/kubernetes/admin.conf inside the control plane node.

That's odd indeed. You'll need to create one using kubectl. This YouTube video will show you how to about creating one yourself as long as you know the URL of the apiserver.

Thank you, @ak2766 . The issue got solved and here is the link to why the nodes were acting weird in the first place. https://stackoverflow.com/questions/69472169/sudo-kubectl-get-nodes-the-connection-to-the-server-localhost8080-was-refused
