Friend Can't Connect to My Unturned Server Using Playit, But I Can

When he joins my lobby and I start a game on my server, the assets appear to start loading on his end. But then it just crashes back to the main menu. This is after reinstalling the game. I’m able to play on the server just fine. Anyone run into this before?

Also, I just noticed my Data Center’s defaulting to New Jersey, which is 16 hrs from my location in IA and 21 hrs from his in OK
