All PCs are physical, no virtual.
PC 1 is running Endeavour OS (Arch based distro) Cinnamon desktop
PC 2 is running Windows 10 Pro
PC 3 is running Endeavour OS Cinnamon desktop
PC 4 is running Linux Mint 19.1
I can use NoMachine to connect FROM PC 1 to the other 3 computers with no problem.
PC 2, 3 and 4 can connect into each other but none of them can connect into PC 1. I keep getting ‘error 104, connection reset by peer. PC 1 is a fresh install of Endeavour OS (like PC 3) and both are fully up to date (pacman -Syu).
PC 1 and 3 are running fresh installs of Endeavour OS. Extremely weird that one can’t accept connection but the other can. Same OS.
