Solution:

- Download https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
- Modify and add "- --kubelet-insecure-tls" in deployment.spec.template.spec.containers.args
- kubectl apply -f components.yaml
- kubectl top nodes
- kubectl top  pod kube-proxy-5p7gr -n=kube-system
