Above error means Kubernetes API Server which is supposed to listen on port 6443 is not running for issue in kubeadm init process. This can be verified by checking if a kube API Server container is running or not by sudo docker ps | grep api
Disable swap and reboot machine
sudo swapoff -a
sudo sed -i '/ swap / s/^/#/' /etc/fstabUninstall and reinstall kubernetes by running below command
sudo kubeadm reset -f
sudo kubeadm initAs a sidenote if you are trying kubernetes on a local system I suggest to use minikube or kind instead of kubeadm.
