Intermittent freezing when connecting from Win11 to macOS 26.2

[noaccess55]

Hello, I’m experiencing intermittent freezing that requires me to exit the app and reconnect from my Windows 11 to Macbook. I’m using NoMachine on my MacBook Air M2 with MacOS 26.2 (25C56). I’m connecting from my Windows 11 pro 25H2 with NoMachine version 9.3.7 on both my macOS device and my Windows 11 device. This is all happening over my local lan. I’m not logged into the NoMachine relay.

I have tried various troubleshooting like getting both machines on ethernet as well as running caffeinate -d in my terminal to prevent the screen from falling asleep. I thought this might be causing the issue. It was actually stable for a while and now the freezing has come back.

What can I do to troubleshoot this?

Hi, when it happens, are you still able to access the connection menu (Ctrl-Alt-0) and click the items in it? We are not aware of intermittent freezing, so complete logs would be useful from both machines. You can extract them using the instructions here: https://kb.nomachine.com/DT08U00298. Please enable debug in the menu on the macOS server as per the article and restart before trying to reproduce the problem.

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

Okay, I sent the email of my logs from both machines at level 6. I’ve enabled the 9-debug and will send those when it happens again.

Logs received. Thanks!

The server-side logs were clean. Please try and get them when you are experiencing the issue.

1) Leave log level to Standard.
2) When you reproduce the freezing, take the player logs from the Windows client side. To do that leave the session window open, go to NoMachine settings > Player > Security > Take Logs.
3) Again, when you reproduce the freezing, go also to the server settings > security section on the Mac server host and click Take logs.

When you experience the freezing how is your internet connectivity?

Hello, okay. I will revert all the logs to standard. Is there anyway for me to clear all the existing logs so i can start fresh?

My internet access is fine when this happens, but I haven’t really been able to reproduce it or pinpoint anything that is causing it. Of course for some reason it’s been stable over the past couple days.

On the macOS machine, you can use the sudo /etc/NX/nxserver --logrotate command in a terminal. Reproduce, then take fresh logs. (see 4.1. Clean-up All Logs in the link above).
