Hello,
I have been playing Arma 3 for a while without any problem on my old computer (Win 7); I bought a new one with higher specs (I've got both Win 10 and Win 11 on the same machine) and installed Arma 3. I ran in the "Steam authentication error", so that each time I try to play in a server, after a while I get kicked. This can happen after few minutes of playing or after hours, it is not constant. I have seen multiple threads on the forum and I have tried different fixes (run steam as administrator, check arma3 profile if it is on read, delete steam, delete arma3, close any other steam applications running on the same time on other machines) but nothing has changed. This is very annoying and, alone, I don't see any way to fix this.
