Trying to play Coop. Mac to PC. 1.8.6. Wont connect

Svperstar

So whenever I host or he hosts same thing happens.

In the console it says blahblah has connected then it will say connection terminated.

No error message no nothing. Like I said this happens reguardless of who hosts. It gives no information as to why. It just says connection terminated. When he joins or I join there is no lag or anything like that. Just closes the connection.

Any ideas?

Thanks

Can you post copies of your doomsday.out (both server and client) from a failed connection attempt please. It might also help if you could describe your connection topology (are you behind a NAT? is this a LAN game? etc).
