Everything was running smoothly with my Kubernetes clusters until today: after performing an update on my Ubuntu system, I'm now unable to establish a connection from my working environment to the kubernetes clusters.

When executing the command kubectl get pods, I'm encountering the following error message:

E0805 09:59:45.750534 234576 memcache.go:265] couldn’t get current server API group list: Get "http://localhost:3334/api?timeout=32s": EOF

Here are the details of my cluster setup: Kubernetes 1.27, bare-metal, Host System is Ubuntu 20.04

Check Docker is running. service docker restart fixed this for me.
