Hi I am getting the next error when trying to login to kubernetes:

kubectl get pods
E1202 15:40:40.098938 23230 memcache.go:265] couldn't get current server API group list: the server has asked for the client to provide credentials

E1202 15:40:40.276627 23230 memcache.go:265] couldn't get current server API group list: the server has asked for the client to provide credentials

I checked that https://technotes.adelerhof.eu/containers/kubernetes/kubectl-unauthorized/ suggest to

kubeadm certs check-expiration

But when I log into the cluster I am getting kubeadm command not found

I think it is an issue related with kubernetes certificates.
