Hello, I had the same problem, however the cause was not on Klei side. I just caught virus Brontok.E which among many other things, installed discretly VPN program that made it impossible to host DST game (although I could "log in" at the start of the game). So check your computers guys! You never know (I wouldnt either, but sudden pc restarts made me wonder..). Hope this tip will help somebody, have fun!
