Cannot log via NX, but detect server via ssh

[diabloto96]

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

From the logs we can see you are connecting to external IP and port 4000.
So you should open port 4000 or use UPnP. Please see the following article for more tips on how to do that:

If that’s not possible, you could try ssh tunnelling with one of the evaluation products, eg. Enterprise Desktop or Workstation. In that case, please check this article: https://kb.nomachine.com/AR10K00728
