error while getting metrics summary from Kubelet

[stefanvangastel]

Hi, thanks for this workaround, followed it to the letter but I'm having the following issue:

The kubectl logs -n kube-system -l k8s-app=metrics-server shows me the following errors:

E0710 10:25:05.002883       1 summary.go:97] error while getting metrics summary from Kubelet host1(xxx:10255): Get http://xxx:10255/stats/summary/: dial tcp xxx:10255: getsockopt: connection refused

E0710 10:25:05.007770       1 summary.go:97] error while getting metrics summary from Kubelet host2 (xxx:10255): Get http://xxx:10255/stats/summary/: dial tcp xxx:10255: getsockopt: connection refused

E0710 10:25:05.021821       1 summary.go:97] error while getting metrics summary from Kubelet host3(xxx:10255): Get http://xx:10255/stats/summary/: dial tcp xxx:10255: getsockopt: connection refused

Using Rancher 2.0.4 and the latest Kubectl cli

$ kubectl get all -n kube-system shows all well

Output from checking APIService:
