Anyone know why, whenever I try to create a game using relayhost(I need to use relayhost, else it won't connect right, not really a problem until now) the game will not be created. Any insight?

try a different relayhost.
in the window with the [x] use relay host there is an option for it somewhere.

I think I'm having the same problem as the OP. After checking the relayhost box, in the list that normally shows the possible hosts it only has automatically select and enter manually.

fixed, try now

Yep, working again, thanks.

its doing it again. cant start a game with relay host here, and just like the OP i need the relay in or people cant connect
