If necessary yes, but you’ll have to upload it to a service from which we can download it because it won’t pass our email server.
For your issue, we’d like to see the stack of the nxplayer and also NoMachine logs as well.
For any core files generated by nxplayer, please see https://kb.nomachine.com/AR09L00810.
For the NoMachine logs, on the device you are connecting from:
– launch the NoMachine UI on the user’s computer from Programs or Menu
– click on Settings -> Player -> Security
– check Don’t delete log files on exit option
– Connect to the server and reproduce the problem.
– Compress the user’s home/.nx directory containing logs.
– Send the compressed logs archive to NoMachine Support Team by e-mail.
On the server side, please see: https://kb.nomachine.com/DT07S00244#1.1
And then the journalctl from the server side as well.
Also, is your Debian installation in a VM? We have not been able to reproduce any similar behaviour on our Bullseye test set-up.
