Re-init kubernetes cluster

I have a multimaster k8s cluster. I had to delete some of the master nodes, and had executed a kubeadm delete m2 and the same for the third node (m3), so that I could have only one master and rejoin the others later. However, this somehow messed with the main node (m1), which now gives me these errors:

The IP address is of the load balancer.

Is there a way to relive this master node, so that I don't have to recreate the whole cluster?

As this was an HA setup, I had no choice but to recreate the cluster.

Here are some troubleshooting steps which you can follow :

1. Try to remove var/lib/kubelet and re-install kubelet.

2. Restarting the kubelet and docker service.

   sudo service docker restart

   sudo systemctl restart kubelet
