Does Co-Op not work?(chap 3)

Me and a friend tried playing it on bnet, and when one of us hosts, the other one got disconnected.

this is 1.16 and we can easily host any other map

is there something we need to do to not disconnect the other?

The game works perfectly for us every time we play it on battle.net. Can you tell me a way to reproduce the disconnect? Does it happen immediately or at some point of the game?

You may try to tune down visual settings. Sometimes the lag caused by slow computers may cause disconnects.

I think we now found the problem and fixed it.
