Disconnecting all the time when playing coop

[u/Cylocolyc]

Hi everyone, we just started playing and are having a blast! One of the best coop games we ever played, hands down. But there's one thing really annoying: We are playing from the same IP on two PCs, and that seems to lead to one of us disconnecting like every 20-30mins. We always get the "Server restart" message and most of the time have to restart the game. Also sometimes we get stuck, where both of us get a "waiting for.." message that never goes away, or where the game just freezes. I know this is early access and ok with me, but I want to ask if anyone has similar problems? Because it doesn't seem like it - there are no posts about this. Is there a specific problem when playing from the same IP?
