VMware VRM Server not able to connect to local vCenter Server

If you install the VRM Server as part of vSphere Replication (this problem is from version 5.0.2) you may see this error in the hms log file.  The HMS logs are located on the VRM itself under /opt/vmware/hms/logs.  You can see how to get these logs from KB2013091.

The error is as follows:

2013-04-12 11:01:14.526 WARN hms.configuration [mai]
(..hms.cfg.VcExtensionChecker) | Extension login failed:java.lang.RuntimeException:

login due to an incorrect user name password.

Now, the problem is that your VRM Server needs to not only communicate to the vCenter on HTTP (TCP 80) it also needs to do the initial connection when the services start on HTTPS (TCP 443).  This was the case in the environment I was working in due to firewalls between the two.  If the VRM Server can only talk to vCenter on 80, it will fail to fully communicate to vCenter.  Once you open up HTTPS between vCenter and the VRM Server, login to the admin page https://<ip of your vrm server>:5480 to restart the services.  It should then connect.  If this is the case for your environment, you will need to follow KB2019120 in order for vCenter to show the health status correctly on the health page for the VRM.  You will also note that KB1009562 which is the Port Number reference for SRM and its' components do not state that this port is required.  I could not get communication functional between the same site vCenter Server and VRM Server until both TCP 80 & 443 were allowed through the firewall to the vCenter server.  I would also allow the VRM server to talk to the remote site vCenter server on HTTP and HTTPS (the kb article only states TCP 80).
