Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Cannot Play Coop online multiplayer on Xbox one

As I posted above:
There are more detailed error messages included in the patch which should help identify the source of any remaining connection issues, if there are any.

There are other contingency plans in place, as well. Hopefully there are a limited number of causes for the connection issue, though, and the fixes in the patch will resolve it for everyone.
