vSphere Agents not collecting any Data

Hello All,

I was hoping someone may be able to assist with my issue.

I am building out vCAC 6.1

When trying to configure a reservation, no resources are available

please note I did not have this issue with  = VMware-vCAC-Appliance-6.0.1.1-1768531

Data Collection does not appear to be working [both vCenters]

no compute / network / storage resources:

also my agent is not logging anything useful::

C:\Program Files (x86)\VMware\vCAC\Agents\vCenter_Backbone\logs

any suggestions?
