The logs show ‘A connection timeout has occurred while trying to connect to ‘192.168.1.250’ on port ‘4000’. The issue could either be caused by a networking problem, by a firewall or NAT blocking incoming traffic or by a wrong server address. Please verify your configuration and try again.’.
That indicates a problem with your router, it could be a double NAT for example, or you have not enabled port forwarding correctly. Please take a look at the instructions here:
How to connect over the internet to NoMachine behind a NAT router
https://kb.nomachine.com/AR04S01122The need for network configuration when using NoMachine to access remote computers over the Internet will be removed when we release NoMachine Network in version 9 (coming soon). You can read more about this feature here: https://www.nomachine.com/network.
In the logs we see ‘out of memory’ errors from the OpenGL functions which NoMachine uses to capture the screen content. Do the new workstations have larger screens or maybe less video memory?
Is it possible for you to send us the logs from the older workstation to compare?
Also useful to know are:
– the desktop environment in use
– did you logout/login or reboot the server after installing NoMachine? (the reason we ask is because a logout/login or reboot enables the default capture method, which in the logs you submitted is not working.)Using DUO has already been discussed in the forum, take a look here: https://forum.nomachine.com/topic/support-for-duo-security-2fa
Are you still able to connect to the machines that aren’t discovered using their IP address?
What macOS versions are installed on all the M1 hosts which aren’t discovering the other machines? And on the M3 host?
Can you also send us the output of this command on the player side?
for DEVNAME in /dev/dri/* ; do LIBVA_DRIVER_NAME=nvidia vainfo --display drm --device $DEVNAME ; doneSorry, forgot to ask you to execute this command in a terminal
sudo /usr/NX/bin/nxserver --eglcapture noand reboot (or logout and then login). Does that change anything?Can you send us the node.cfg file of the NoMachine server, and also the output of this command:
/usr/NX/scripts/vgl/vglrun glxinfo | grep -i “renderer\|vendor”
In the logs we can see that the server sets the LD_PRELOAD library. Maybe is not set in your user profile?
The attachments were not working for some reason and so they have been removed. Can you send them directly to forum[at]nomachine[dot]com, please?
I assume you’ve got 8.14 on the Windows computer as well.
When you say “after rest” in the title, do you mean you start the session to the Mac and leave the session open/running, and then go back to it after some time?
UDP traffic goes through port 4000, this has been the case since the first release of version 8. Using ports 4011-4999 would not improve performance.
Is the display server X11 or Wayland? On Kubuntu it’s x11 by default, maybe you installed Wayland and are you using that?
Logs would be useful from both sides. You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243
