3 days server issues in Diablo 4!

I can’t play the game for last three days, cause my ping spikes to 300+ and game start to lag as hell.

No helpful information, no packages losses, everything fine even in other Blizz games as Overwatch 2 and HotS.

Any suggestions, please?

Have you changed anything in your game options like enabling cross platform play or graphical options?

D4 is very sensitive to local conditions. The white knights love to claim you’re the problem because you’re running on a potato but it’s actually the way the game is designed that causes the problems. Working around it often amounts to changing something on your end to accommodate the game.

Typical issues are things like VM file size, graphical options (including driver updates), and some game play options (like cross platform). I’ve been playing in HC just fine for the last two weeks. Finished the season journey and earned my raven pet yesterday. So it doesn’t seem like the servers are the problem.
