Error 108 for Windows -> Ubuntu with version 9.3.7

[danergo]

Folks, please help me.

I’m running the latest NoMachine on both my Linux Ubuntu (server), and on Windows 11 (client).

It was working before but now nxnode.bin segfaults.

Server: Ubuntu 24.04.3 LTS, Kernel: 6.8.0-90-generic

Journal log:

Problem is most probably in libnxdimi, because once I move it away, problem goes away (but then I can’t see the desktop, because it can not be detected):

sudo mv /usr/NX/lib/libnxdimi.so /usr/NX/lib/libnxdimi.so.disabled

I also did a gdb core backtrace for you:
