Can't play overwatch for over a week

For over a week I couldn’t play overwatch because of constant disconnects which happened out of nowhere and I can’t find a problem of this I checked everything on my side I tried every blizzard article contacted my ISP, I used other pc (which worked fine while on my pc everything works as it should except overwatch), I use ethernet, I tried to use mobile hotspot and nothing works. I really need help.

Anything would be helpful

Do you get any error message, be it in a message box or just on screen? Might be helpful to mention whatever text appears when you get disconnected.

It seems like it just fixed itself, idk what caused it to fix

edit: well nevermind it again disconnects me after about 30min, one day fix i guess
