do a rs.status() - https://docs.mongodb.com/manual/reference/method/rs.status/ — Kevin Smith, Jan 23 '18 at 13:13

I found the solution of this.

It's just MongoDB version issue.

My primary server configuration is.

MongoDB shell version v3.6.2

And My secondary server configuration is.

MongoDB shell version v3.4.10

I am updating my secondary server to v3.6.2 and I can add my secondary server IP in a member of my replica set using rs.add() and it's working good.

Thanks for the support.

Two things...

First, check firewalls! Every node must have a possibility to connect to other nodes.

Second, you cannot use localhost address(es) if all nodes are NOT at same computer. So, if you are already configured first node using localhost address, you cannot add other nodes with IP addresses, all addresses must be (in that case) localhost i.e. same computer but different port.
