My Mac system is Sequoia. I can see on my Mac and connect to NoMachine server on PC wir Win 11.
On RPi i have Ubuntu 24.04.1 LTD 64 bit with Mate, NoMachine 8.16. RPi player can see and connect to PC as well.
For some reasons, overnight, my Mac started to see RPi NoMachine after I turned off Windows PC (both can be connected)
I also installed NoMachine on iPad but neither PC nor RPi can be connected.
