Is NetworkError node dependent on Netdriver/Subsystem?

I’m trying to get the listen server to react to the client shutting down unexpectedly and this event never triggers.
I have lowered the timeout number in the .ini file to 5 seconds but still I never get a trigger of this event.

Is it dependent on the Netdriver or Subsystem? I’m using Oculus OSS and I’m thinking this could be the problem?
If not what could it be?

Cheers
