I have installed SRM into our Vsphere environment. I used credential authentication. SRM installed and started ok at both sites. I created a pairing between both sites. Each time I start VI and select SRM I get prompted for pairing credentials. I entered that information and the pairing switches to port 443. I have a case open with vmware on this issue. They looked at the logs and said the issue might be using FQDN and IP addresses on the SRM install. I uninstalled SRM and installed using just IP addresses for hosts. No luck. I uninstalled and used just FQDN. Same results. Waiting back to hear from support but wanted to put it out here as well.
