Call of Duty Warzone - Server connection disconnected. You have been disconnected from Call of Duty: Modern Warfare servers. What to do (PC)

Server connection disconnected. You have been disconnected from Call of Duty: Modern Warfare servers. Please try again later…

I play Warzone on the computer (PC) via Battle.net.

About 5 days ago I was able to play Warzone without any problems, now this error message every time.

It feels like I've tried everything for several days to fix the error message, but nothing worked.

I've already tried all of this:

1). I restarted my computer 2). Router restarted 3). Uninstalled and reinstalled Warzone 4). Reregistered on Battle.net 5). Checked on the Activision page whether the accounts are linked. 6). Checked whether the servers are really online. Are you! My roommate can play on his Playstation and another friend can also play online on his computer 7). I reset my network settings 8.) Asked Activision without getting an answer 9). I tried to log on to the American server without success. 10). Open via administrator 11). Checked my entire computer for updates, everything is up to date 12). "Scan and repair" the game via the Battle.net Launcher, again without success…

It can't be due to my computing power, I have good components. My internet connection is very good, never had problems in other games.

I really don't know what to do next, maybe one of you has a solution. I would be grateful for any help!

Looks like the last thing you can do is reset Windows or reinstall it.

That would be the last option, unfortunately a bit cumbersome.
