I have a headless server with installed NoMachine and I’m getting :
The session negotiation failed. Error: Cannot create a new display, please contact your system administrator
NX> 105 Listsession --status="disconnected\054connected" --type="all" --shadowable="yes"
NX> 500 ERROR: Cannot create a new display, please contact your system administrator.
NX> 127 Session list of user 'ats':

NX> 148 Server capacity: not reached for user: ats
NX> 105
My settings /usr/NX/etc/server.cfg
DisplayOwner ats

But (not sure if related) If I create and connect to server via VNC, restart NoMachine server few times and try reconnect few more times with NoMachine – it will connect. Any ideas?
