Orchestrator 5.5 Setup

We're running vCenter 5.5 web client and I'm trying to set up Orchestrator. The ova has been imported and configured to point to vCenter, however when I try to point to the VCO appliance in vCenter by IP, I get the error "Failed to connect".

Also, when i set up the connection to vCenter on the VCO Configuration page, it connects successfully, however when I open the VCO client, it shows vCenter with (invalid credentials).

Am I missing something?

Thanks,

Scott
