-		Unfortunately, an error has occurred:

-		This error is likely caused by:
-			- The kubelet is not running
-			- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)
-
-		If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
-			- 'systemctl status kubelet'
-			- 'journalctl -xeu kubelet'
-
-		Additionally, a control plane component may have crashed or exited when started by the container runtime.
-		To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
-		Here is one example how you may list all Kubernetes containers running in docker:
-			- 'docker ps -a | grep kube | grep -v pause'
-			Once you have found the failing container, you can inspect its logs with:
-			- 'docker logs CONTAINERID'
