I was playing earlier today with a friend and the game was working great, vanilla, no mods. We both decided to get Annunaki and suddenly my friend is getting "Host connection timeout" every time he attempts to join my non-dedicated server.

I have tried verifying the integrity of game files through Steam among other things, but nothing seems to work.

What should I do?


My specs:

Intel Core i5-4590 CPU @ 3.30 GHz
Radeon RX 570 8 GB
16 GB DDR3 RAM
