Kuberenetes master to node connectivity

Question

I am trying to execute kubeadm join master-ip:6443 command on the new worker node I want to join to the existing kubernetes cluster

But there is no connectivity between the master and new worker node I am trying join.

I want to know on which source and destination ports I need to raise the fireflow connectivity.

Is it from source: master-Ip:6443 to destination: workernode-Ip:6443

Do i need to open up ssh dedicated port 22 also?

Are both machines are in the same network? Can you ping between both machines? — PjoterS
use this command kubeadm token create --print-join-command on master node and execute that join command on worker node — Dhanraj

The connection will be through 443. Please try using 443 instead
