@matthewmandegar said in Host is NOT registered!:

we have to use USB-C>RJ45. when I PXE boot iPXE see the SYSTEMS MAC but once connected to FOG and I register it see the DONGLES MAC.

Have you looked into the UEFI/BIOS settings yet? Played with the MAC passthrough setting?

also here are the errors that I see when registering.

Don’t worry about this as long as it’s proceeding after that. ACPI errors don’t mean too much.
