I have been seeing this message after my server got rebooted. Everything worked perfect before rebooting the server so I am not sure what needs to restarted I checked config file and restarted some of the services but no luck

kubectl get nodes

The connection to the server 192.168.1.228:6443 was refused - did you specify the right host or port?

    Hi @raziahmed,

    What type of VMs are hosting your cluster? What is the OS installed on these VMs?

    Have you checked to see if the container runtime and the kubelet services are active and running?

    sudo systemctl status kubelet.service

    sudo systemctl status containerd.service

    If one of them or both are stopped you can start the one of both and check status again:

    sudo systemctl start kubelet.service

    sudo systemctl start containerd.service

    Regards,
    -Chris

    Try also turning off the swap memory if enabled

    swapoff -a
