Me and a friend made a private game. He hosts. First day all good, second day I can't join. Game just crashes without error code or anything. Sometimes it just goes to main menu, most times closes. Tried all the normal troubleshooting including connecting with directIP, and verified files. He hosts a new game, I can join just fine. We move over stuff and play for a few hours. Today we're going again, but same connection problem happens. Game closes once, rest of the time just goes to main menu when I'm trying to connect to him. No error msg, game files verified. Neither of use VPN or have done any changes to network settings.
