I have a cluster that I just can't seem to make happy. No matter what I do, Node 1 shows a connection to node 2. Node 2 does not show connected to node 1. These are the only nodes in the cluster. 1 is of course the primary/master. The diagram shows one red and one green line going between them.
These are both behind firewalls talking to each other to NATed IPs. One's https website is on port 442. Both have port 23570 open for incoming traffic and the firewalls configured to allow outgoing traffic. The DNS names on both ends properly resolve to the external IPs they need to communicate with.
What else might be getting in the way of this communication?
