OpenView NNM: Global Manager to Regional Manager connection fails

Global NNM 9.23 on Sun Solaris 10 and Regional NNM 9.23 on Sun Solaris 10

When I try to connect to Regional Manager from Global NNM on port 80 I receive an error,
Invalid Regional Manager Connection configuration information provided. NNMi cannot connect to : http://rnm.domain:80/nnm

I am confused because I can connect other regional nodes to the this global manager and I can connect this regional node to another global manager

Any thoughts?

What happens if you curl/wget the url from the global manager?

It won't connect at all.  It continues to say connection: Not Established.

Can you ssh or do some other connection (ping, telnet to an open port) to the regional node from the global manager?

Is there a firewall blocking connectivity anywhere?

I can ping it, I can ssh in to it. I can even bring up it's nnmi page via a browser on the global.  I had the network guys check all the ports and connections.  No firewall and no connectivity issue.

I have reloaded the system twice and same issue both times.

I  have done 22 systems and this is the first time this has happened.

on the regional server run tcpdump against the interface while trying to connect from the global server, just to see if you get any traffic on the port from the global server.

The error seems to be connectivity so lets check that. If you are getting traffic to the right port from the global manager it may be a configuration on the regional server needs checking.

The reason I choose this as the best solution is it pointed me in a direction other than software,  Which probably wasn't the intent.  The main line fro the switch was broke and the fail over switch cable wasn't even ran.  So had to have the hardware guys come and finish their job and fix the other cable.  Once that was complete the system came up no issues.
