BritgirlKeymasterWe’ve since released NoMachine 9.5. Can you update and tell us if you are still encountering the same problem? If you are, after reproducing, go to Settings > Server > Security, and Take logs from the headless Ubuntu server. Send us the full zip file. If you prefer to send privately, send it to forum[at]nomachine[dot]com.
BritgirlKeymasterSo you can now connect without any problems? Good to know.
BritgirlKeymasterUsers that were encountering this issue with earlier v9 installations should make sure to update to the latest 9.5.
BritgirlKeymasterTo make sure the NoMachine logs are preserved is to edit the node.cfg file and set the key ‘UsersDirectoryPath’ to a directory that can be accessed by everyone e.g. to the main NoMachine log directory:
UsersDirectoryPath "/usr/NX/var/log/users"then ensure the directory is available for everyone:
sudo mkdir /usr/NX/var/log/users sudo chmod 777 /usr/NX/var/log/usersthen please restart NoMachine:
sudo /etc/NX/nxserver --restartand try to connect to Login Window again and collecting logs using
sudo /etc/NX/nxserver --debug --collect
BritgirlKeymasterHi, please update to 9.5. If you are still encountering the same problem, after reproducing, go to Settings > Server > Security on the macOS machine and click Take logs. Submit to us the whole file. You can attach it here or submit to forum[at]email[dot]com. Thanks!
BritgirlKeymasterHi, could you try the latest 9.5 and tell us if you still encounter the issue?
https://kb.nomachine.com/TR03X11769 – this TR was solved in the latest update.
BritgirlKeymasterCan you send us the logs from the server side machine? On the server, go to Server > Security > Take logs, save the file and send that to us. You can submit it here or if you prefer, you can send it to forum[at]machine[dot]com. Please use the title of this topic as the subject of your email. Thanks!

BritgirlKeymasterYou should disable sound on the server. Set EnableAudio 0 in the node.cfg file. Does that help?
BritgirlKeymasterNot sure what your products is so I’ll point you to one of the Terminal Server v8 guides: https://kb.nomachine.com/DT07T00259#2.3. You’ll find all the v9 guides on our support page 😉 https://www.nomachine.com/support/documents
You can also refer to this article https://knowledgebase.nomachine.com/AR10K00698
BritgirlKeymasterIt sounds more like something is broken on the system OS. There are references in logs to ‘/run/user/60578/’ so this directory has to be present. Maybe you could investigate the user with uid 60578?
BritgirlKeymasterNo, but in the upcoming version 10, when you publish a machine to NoMachine Network, and are logged in while doing so, it will be automatically added to your Machines book. Can this be helpful to you?
BritgirlKeymasterHi,
On Enterprise software it is still possible to add machines to NoMachine Network even if the license has not been activated yet.
Do you receive an error message? Can you go to the Server settings > Security and click Take logs? Please submit these.Also tell us:
– version of NoMachine software
– which specific product you installed
– did you try a reboot after installation?
– can you tell us if in Settings > Server > Security the server is showing as running?Activating the license can be done by following the instructions here, skip straight to “How to install the license”: https://kb.nomachine.com/AR10U01206#3
If you have a full Enterprise subscription, please consider opening a support enquiry (you can do this from your User Area) because some of the details that we ask you could mean showing sensitive information. For this reason, your image has been removed from this topic.
BritgirlKeymasterHi, server logs would be useful. Go to the NoMachine server settings on the Zorin OS >Â Security > Enable debug in the logs, restart, reproduce, collect and share logs with us. You can attach them here or send directly to forum@nomachine.com (make sure to use the title of this topic as the subject of your email).
