My container engine cluster has a red exclamation mark next to its name in the Google cloud console overview of the container engine. A tooltip says "The cluster has a problem. Click the cluster name for details." Once I click the name I don't get any more infos, it's just the usual summary. Stackdriver doesn't report anything unusual. No incidents are logged, all pods are marked as healthy but I can't reach my services. Trying to get infos or logs via kubectl doesn't work:
kubectl cluster-info
Unable to connect to the server: dial tcp xxx.xxx.xxx.xxx:443: i/o timeoutHow can I debug this problem? And what does this cryptic message mean anyway?
Are you able to use other kubectl commands such as kubectl get pods?
This sounds like the cluster isn't set up correctly or there's some network issue. Would you also try kubectl config view to see how your cluster is configured? More specifically, look for current-context and clusters fields to see if your cluster is configured as expected.
