Hello.
No, you’re not doing anything wrong.
Could you provide NoMachine logs to us?
You can find it in C:\Documents and Settings\All Users\NoMachine\var\log,
just zip this folder and send to us.
Could you also try doing this:
- Open “NoMachine Service” switch on “Server Preferences” tab.
- Choose devices tab.
- Switch off all check boxes.
- Click “done”.
- Restart server.
- Check connections again.
If you still notice problem, report to us please.
Thanks.
