Server running but NX service stops

[tomino]

I’m on Kubuntu 20.04 and although my local NoMachine server is running, when I start the NX service it runs for a few seconds then stops. The error shows that “Listening failed on port 3389 TCP” and “Error is 98, ‘Address already in use'”, but I can’t seem to find what else is using this port. I’m running the latest version 8.13.1 and the log file is attached. Any suggestions are welcome. Thanks.

I managed to resolve this problem. I had installed the xrdp server package a while ago for remote access to my Kubuntu server from a Windows system via Microsoft remote desktop, and it seems like it was competing with listening to the same port number 3389. It wasn’t clear at first since xrdp wasn’t shown as listening on this port (actually nothing was shown as listening on this port), but it came up once I reinstalled NoMachine. So I simply remove xrdp and restarted the NoMachine server, and the NX service now stays on/running.

Thanks for following up and we’re happy to know you solved the issue.

For future use, and if you need a list of ports that NoMachine relies on, take a look at the following article: https://kb.nomachine.com/AR01L00770
