No network conections on File tab on Linux box 2022.2

Weirdest Problem on both our 2022.2 Flames.
Cannot conect directly to our network using tbe FILE tab in MEDIA HUB. When we do… CRASH.
Worked perfectly well yesterday, no network changes overnight, no one else using the machines, just happened this morning.

Work around is navigating to the other Flame using the AUTODESK NETWORK and then connecting to the network from there, and visa versa with the other Flame…

And that works…

Any ideas???
