Nxserver restarts after “Reached maximum NXD restart counter” warning

[ivan3000]

New install of NoMachine Terminal Server  7.8.2 on RHEL 7.6

The nxd service crashes and is restarted until it reaches the maximum restart counter, as seen in log:

NXSERVER WARNING! Reached maximum NXD restart counter.

Debug logs sent to forum@nomachine.com

Any idea what is wrong with the installation?

SSH works, but would like to use NX protocol since its probably better performance.

It could be that port 4000 is already taken. The Network Server (nxd) listens by default on port 4000. If you have another application using port 4000, you can change it for NoMachine in server.cfg.
