KUBERNETES - The connection to the server 192.168.181.11:6443 was refused - did you specify the right host or port?

Today when I started by Kubernetes setup (ubuntu1-master node) and ran the command kubectl get nodes I received the below error:-

Error:- The connection to the server 192.168.181.11:6443 was refused - did you specify the right host or port?

In order to solve the issue I ran the below commands on the master node:-

1. sudo -i

1. swapoff -a

1. exit

1. strace -eopenat kubectl version
