Adding vCenter 5.1 to OpManager

Adding vCenter 5.1 to OpManager

I have upgraded to v10 of OpManager and watched the video showing how to add vCenter to OpManager.  I have also created a credential specifically for vCenter that has administrative rights.  When I try to discover the vCenter server using the credentials I get the error "Failed to connect the VMware Host WebService(Device may not be reachable/Credentials may be wrong)"

We have not been able to find anything on ME's website that say they support v5.1.  Any thoughts?
