Don't waste your time. Blizzard servers are completely ignored for D4. Me and thousands of other people have constant lag issues that make the game completely unplayable and they have done nothing to fix it regardless of the numerous complaints. extremely disappointed in the amount of money I spent for a game I cant play.
And yes I have checked everything on my end and its not me. Every other game I have played without issue, it is only Diablo 4.
