Connect successfully, then immediately disconnects

[kouhei_ioroi]

NoMachine Version:8.4.2

Server:Microsoft Windows 10 Pro(x64 Virtual machine on Proxmox)

Client:Microsoft Windows 10 Pro (x64 Physical machine)

I wanted to install and use NoMachine on a Windows 10 Pro virtual machine on Proxmox VE. The installation was successful and the connection using 127.0.0.1 was successful. However, when I connect from other clients, it logs in successfully but immediately disconnects. I searched the forums and tried various methods, but none of them gave good results.

Is there any better way to do this?

Hi, we are regular users of Proxmox in our labs and we have not come across disconnects as you’ve described.

When you connect from other client machines, do you see an error message of some sort? Can you show us the dialog that you see when you get disconnected?

Can you send us the logs of the client and server sides? See the following article for further instructions: https://kb.nomachine.com/DT11R00181.

You can submit them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!

Hello Britgirl.

I’ve tried uninstalling and installing several times and the behavior has changed again.
Access from 127.0.0.1 is also failing now.

Also, immediately after connecting, it changes to “Desktop not shared” and returns immediately.
I suspect that maybe the nx server is crashing.

I have sent the log to your email address. Please check.

The current error screen is as shown in this image.

Thank you.

Please uninstall NoMachine, perform reboot, install NoMachine and perform reboot.

This should bring you back to a situation where you can perform localhost connection but connections from remote fail. In that case, enable debug logging and gather the logs according to the already provided instructions.
