error code 4-0xFFF0BE25 "you have been removed from session."

[Thee Golden Taint]

this is the fourth time getting this error and all have been in ranked games, I'm on a two day ban for something I can't even fix.

I have tried to delete and redownload, close all background apps, verify files, everything I can find on forums to "fix" this issue. Also has been days and Ubisoft still hasn't replied...
