vSphere Data protection 5.8 not visible in vCenter Web Client

Hi,

I've been struggling with VDP for a couple of days now.

Here's the setup:

• vCenter appliance 5.5 U2
• 1 VDP 5.5.6
• 1 VDP 5.8

The VDP 5.5.6 is there since a long time ago, it's running fine and I can manage it no problem in the vCenter Web Client.

But, cannot see the "vSphere Data Protection 5.8" option. Therefor I cannot manage the VDP 5.8.

The VDP 5.8 is a fresh install. I've tried registering it using three different users and it doesn't seems to do the trick.

vsphere.local\Administrator

vsphere.local\VDPAdmin (This is a user that I created for the purpose)

MyDomain\VDPAdmin (This is an AD account in my domain. Of course MyDomain is not the real domain name )

All three accounts had permissions defined at the root level of the vCenter as administrators.

Each time it registered successfully. I've rebooted both vCenter and VDP appliance numerous times.

Any help would be appreciated.

Thanks.
