OMFG THESE DISCONNECTS

My computer is not the problem. every other game I play works fine.
WHY IS IT that I can't play this game for more than 5 minutes without "An Unexpected Disconnection Has Occurred" kicking me out of the game...????
I bought this game when it first released, I've beaten the campaign multiple times and yet now, nearly a year later when I try to play again, I am CONSTANTLY disconnected. I have watched every youtube video, followed every "tip and trick" and nothing works.. My fps is flawless, my game runs perfectly fine, and then all of a sudden my MS spikes to anywhere between 7k and 25k and kicks me out of the game.. I cannot believe I paid money to not even be able to play this game. guess I'll go play Diablo 4. Atleast it works.

There is some isp that route things to usa and back if one plays in europe due to some things going on with them.
Cant do much if that is the issue
