@sheiksharfuddin, even though I have not encountered it as off a setup last week, this seems like a known issue.

Try creating the relavant auth configu from the control-plane(master) node as ,

kubectl create clusterrolebinding cluster-system-anonymons --clusterrole=cluster-admin --user=system:anonymous

You could further try out the solutions listed in the following threads.
