Did you find a solution to this? 

I get the same error after installing vCenter 5.0 Update 3e when trying to view the Hardware Status Tab of my ESXi 4.x Hosts.  It was working before I installed Update 3e.

Got the same problem after upgrading to vcenter 5.5U3, it was fine with 5.5U1. I don't want to remove and re-add the host as it will take too much reconfiguration. Newly added host appears fine,only the old one got the problem.

How can I solve the invalid SSL cert problem?
