Adding new node is failing

Elastic Stack Elasticsearch
1

Hi there,
I am an ES newbie, and having a problem adding 2nd node. I am getting an error below. So I set up Shield on my master node with few users, and I am guessing I need to something on 2nd node so it can find the master node, but I haven't been able to find any doc on this. I already installed Shield on 2nd node too. Let me know.. thanks!!

Both nodes should have the same Shield config, is this the case?
Can you ping the nodes and telnet to 9300?

Not sure why, but it's working now. Thanks though!
