Hi all ,
We added a new node at one of the our customer. But the newly added node still does not appear after 3 days. Our customer gets error as below. I wonder that, should any port need to open between two cluster nodes on the same host ?

You've added extra DT node on the same host? This is not supported option I suppose. In general network ports should be opened if first node is working fine on the same machine. But there is issue with SSL certificate validation. I'm not sure if there isn't any issue with certs because od architecture you've picked. Why did you do something like that?
