Hello. I have been playing FAF for a couple months now, and these last couple days I have had an issue where when I create a lobby, it takes a long time to boot the game, then gets stuck on the connecting to server page. Today, instead of that, when I create a lobby it waits a while, then throws this error:
Client Version: 2025.2.1

Suppressed: The stacktrace has been enhanced by Reactor, refer to additional information below:

I am trying to create a lobby with FAF develop and two UI mods that I have used before(improved graphics 2024- extreme quality and redux strategic icons large).
