Me and my wife had played through original version of the game with little problem. We could play Divinity Original Sin 1 with little problem. We've completed DOS2 original one a year ago. But DE doesn't work most of the time.

I've tried to play with configuration, reloading, reinstalling the game... And then suddenly it works. But after a couple of hours she disconnects and can't connect back. Then on the next day after several tries it works... Till it disconnects and stops working again. We only had two sessions and couldn't get another.

The real problem is inconsistency. It'd be easier if it just didn't work; but it works sometimes. Than I don't change anything and it stops working.

One idea is maybe the game chooses connection ports randomly and most of those are locked but some work?..
