Sites only show as connected from Primary vCenter.

Hi. I'm running SRM 5.1.1 with vCenter 5.1 Update 1. Primary and secondary sites separated by physical firewalls. I've followed the kb on ports:

http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&externalId=1009562

I've tested with telnet and I can successfully connect from primary SRM to remote vCenter over 80, and vice versa from remote SRM to primary vCenter. Each vCenter can successfully communicate with their own local SRM server over 8095. In the primary vCenter I'm able to successfully establish reciprocity, and after I'm prompted for the remote vCenter creds, I see both sites successfully connected.

Now, when I hop over to the remote vCenter (recovery site) I'm able to establish reciprocity between both sites, but when the prompt comes up to enter creds for the remote vCenter (primary site), I get an error that comes back as "Unable to connect to the remote server"

Not sure where the issue resides. Any help most appreciated.

Thanks
