Over what port do JIRA Datacenter nodes communicate with each other? I am unable to locate this information in the documentation. I need to run the nodes with the OS firewall enabled. When I enable it, I see these errors in the nodes:
...threw a connection exception. This could mean that a node has gone offline or it may indicate network connectivity difficulties. Details: Connection refused to host: CU019; nested exception is: java.net.ConnectException: Connection timed out: connect
They go away when I disable the firewall. I am able to hit the nodes in the browser successfully using port 8080, as I have opened that port in the node firewalls.
Thanks for your help.
At a guess, this would seem to be port 40001 based on the JIRA Datacenter installation guide.
