Q: KubeConfig doesn't work, not valid for kube-vip IP, only for some "random" IPs in flannel network.
2021-11-06 09:14:28 +00:00
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
