Hi
After some time I had to update NoMachine to latest version (9.0.188.11). Now I cannot connect to the server:
Server log is attached below. Any hint would be highly appreciated.

Hi Strider,
In order to investigate, we need logs – can you please gather them with debug enabled?
In order to do so, follow the instructions in this document: https://kb.nomachine.com/DT07S00243. It’s valid for v9 as well.
Reboot the server, or logout and log back in.
Gather logs again, and send them to forum[at]nomachine[dot]com, making sure to reference the topic as the subject of the email.
Hi Bilbotine,
I have managed to solve the issue myself. Primary reason – that it is headless environment.
In case there is no actual monitor connected to the GPU, NoMachine was not able to connect, with not exactly explanatory error.
After “fake monitor” dongle has been plugged in – issue self-resolved.
Thank you for your help.
