Issues since 2023.3.0

I have been playing FAF for 3 years. All was great with the occasional slow down.
However since 2023.3.0 it seems that I cannot join games with certain players.
Lobby will say "connecting to Natadiem" forever...
Didn't change computer nor ISP, exact same hardware.
Any clue what could be this problem? I play from Singapore. Cheers
