Dell/EMC System Update - could not get the inventory

PE630 with Windows Server 2016 - fully patched.

Tried an uninstall, reinstall, reboot, etc and cannot get Dell System Update 2.0.1.0 to run. This is what happens when I try:

C:\WINDOWS\system32>dsu

Getting System Inventory ...
Could not get the inventory
Progress report is available at:C:\ProgramData\Dell\DELL System Update\dell_dup\DSU_STATUS.json

The json file mentions only has this

{"SystemUpdateStatus":[{"System":{"id":"NA","idType":"NONE","hostAddress":"LocalHost"},"InvokerInfo":{"name":"DSU","version":"2.0.1.0","command":"NA","exitStatus":1,"statusMessage":"Could not get the inventory"}}]}

Tried deleting the c:\programdata\dell\dell emc system update\dell_dup folder and running it again. Same result.

Also noticed that if I go to www.dell.com/support and try to do updates from there, it keeps saying that Dell Support Assist needs to be installed, even though it is. When I install it, says it is already installed and the support site will not detect my hardware/service tag. 

Any suggestions would be appreciated.
