kubernetes control plane goes down often

I did setup a kubernetes cluster using kubeadm. Somehow kubectl refuses to connect to that cluster in non-periodic occasions with an error message as in the following;

The connection to the server 192.168.1.3:6443 was refused - did you specify the right host or port?

I am guessing that my cluster going down and restarting itself? Can someone provide me some insights.

Could be many things, starting with network problems. Check logs on the cluster to see if it restarted

I have installed docker first which comes with containerd. containerd uses cgroupfs. While kubeadm uses systemd by default. I have realized that kubelet service crashing over and over by checking its log with journalctl.

Now I have installed cri-o instead problem solved.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
