Error 121 from GetOverlappedResult

Submitted by Jacky5722 on #1

Hello,

We're using this tool as a way to share licensed products amongst the unit.  I loaded the USB dongle to my computer and ran our program.  Initially it operate just fine but after working for about 5 minutes, the USB dongle disconnects with this error.

Any ideas on how to prevent this from happening?

You must use the virtualhere server on a real machine, not inside a VM or container.

Virtualhere is running on a physical machine.

The dongles are attached directly into the machine.

My computer is on the same network at the machine and the client picks up the server no problem but after about 5 minutes of using the dongle,it disconnects.

Any other suggestions?

OK are you using win10 or win11? If you can make sure to use win11. Also what dongle is it?

It looks like this version works and doesn't disconnect the dongle

Thank you
