Error: Cannot create a new display, please contact your system administrator

[willie108]

Hello. I have used NoMachine to connect to my virtual ubuntu-2004-focal-v20211202 machine on Google Cloud. Then I expanded the boot disk and now I am getting this message. I am using Windows 10.

The session negotiation failed. Error: Cannot create a new display, please contact your system administrator

The NoMachine version is 7.7.4

I am a complete novice with networking. Thanks!

The log files look like this: (see attached)

Hi the logs (which were long and for this reason were extracted and attached separately) were from the Player side. We need logs from the server side to understand why the NoMachine server cannot create a new display.

You should also tell us what desktop environment your VM is running. From what you submitted in your original question, I can’t see a desktop GUI running there. You can install one using sudo apt-get install ubuntu-desktop.

Please take a look at our tutorial for Google Cloud users:

https://www.nomachine.com/accessing-your-remote-desktop-on-google-cloud-platform-via-nomachine

If none of our tips and suggestions work and you can submit logs from the server which can be extracted using the instructions here: https://knowledgebase.nomachine.com/DT11R00182

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