"System Back Online" trigger does not work on every (virtual) machine

[AXGui]

I have a Macbook and a windows laptop that are both starting the workflow that is started with the trigger "System Back Online".  Building a virtual test machine to re-build our onboarding (we are in migration to Pulseway), the workflow is not started on this virtual machine.  Computers are all in the same organization\group.  Only diff is physical vs virtual.  Could that be an issue? Any other pointers/reasons to check maybe?  Thx

Systems need to be offline for x minutes before the workflow trigger " System back online" is activated. 

We have created a script a. disable the NIC an b. will create a scheduled task executed in 10 minutes and that will restart the computer.

NIC gets disabled, system will wait 10 minutes, restart (where the NIC will be enabled automaticly) and workflow trigger will be started
