HDP not recognizing Windows VMs running under Hyper-V

Dear all,

I used to backup Windows VMs running on a Windows Server 2022 Hyper-V machine.

Since around August 14th HDP doesn’t recognize the Windows VMs anymore. I also have a Debian VM on the same Hyper-V host and this one is fine.

The Windows VMs are grayed out when I check the inventory.

Could be related to a recent upgrade of the OS and HDP.

Firmware:
QTS 5.2.10.3577

HDP for PC/VM

Version 2.4.0 (2026/08/04)

Any idea what could have broken a working process?
