Blizzard Servers

I have been playing WARZONE for a few years now. I haven’t had many issues like this year. I have been getting DISCONNECTED from Blizzards SERVERS. I have tried everything I know now to do.
I uninstalled the game and reinstalled it
I installed the game on STEAM (did’t work)
I flashed my DNS in Command Prompt.
Reset my modem and Router
Talked with my INTERNET provider (everything is good on there end)

I don’t know what else to do. Anyone have any IDEAS, please let me know. Thanks
