Constant disconnects on Series X

Just redownloaded D4 for the first time since launch month and am completely unable to play couch co-op as the game disconnects every 20 minutes or so. Doesn’t matter if it is in a dungeon or the open world.

I have deleted saved data, uninstalled and redownloaded the game and have turned off cross network play. Nothing works.

Game is literally unplayable at the moment. Anyone having the same issues or a potential solution?

Thanks!

Some days ago D4 start to suffer from constant rubberbanding, freezing helltides, world boss being unplayable due to lag, frequent server disconnections.
In this state this game is unplayable
