I am unable to connect to a (free) NoMachine server on a Ubuntu 20.04.5 LTS (Gnome) machine, from a Windows 11 machine or Windows 10 machine.
I think it’s happening via a physical display? I didn’t change any option related to that in any case.
I know I am on the right network, because I can log via a direct ssh connection (not on the software) from the client computer. If I use SSH on NoMachine, it detects the server but says the session is not supported via SSH on that server, and suggest switching to NX. Then, it times out.
I have collected both client and server logs as detailled in https://kb.nomachine.com/DT07S00243.
They are attached.
Server: Linux 8.1.2, free version
Client: Windows 8.1.2, Enterprise Client
