 Q: KubeConfig doesn't work, not valid for kube-vip IP, only for some "random" IPs in flannel network.
 A: This can happen when cluster is restarted, maybe if rancher pods are restarted, can be fixed with: kubectl annotate secrets -n cattle-system tls-rancher-internal listener.cattle.io/cn-<kube-vip>=<kube-vip>
 <kube-vip> = cluster IP address
+kubectl annotate secrets -n cattle-system tls-rancher-internal listener.cattle.io/cn-172.18.0.20=172.18.0.20
