[VSC]virtual storage console is not running

I encountered "Unable to connect to Virtual Storage Console server"albeit working on a lab environment (vSphere 5.5 with Windows 2008 R2 vCenter and 7-Mode ONTAP 8.2.1 simulators). Like you VSC was visible, reportedly sucessful registration and NetApp privileges installed into vCenter.

Mine's now sort of fixed - I'd created a specific user role for registering plugins with vCenter that only has the Extension: Register, Unregister and Manage privileges and used that to 'successfully' register VSC. I went back and re-registered the VSC on the https://localhost:8143/Register.html url (capital R!) using the root administrator@vsphere.local account and now VSC works (added controllers etc and optimised ESXi hosts)

The SSO admin is overkill and i need to go back and read the furnished material to confirm actual registration account requirements before I hit production. May be a starter that helps fix your issue.
