Me and 2 other friends tried to connect, and we all made a lobby per person to see if it was because of someone's internet, but we were on the same server and just copy pasted each others' codes from Discord. It still gave an error message saying it couldn't connect.
The server I was using to host the lobby and do the relay must be down and I can’t get it back running.
Unity bought the multiplayer package I was using to make the game and they changed it so much I’ll practically have to start the game from scratch again if I want to modify it and fix the lobbies.
I’ll be working on a new version later this year but for now there’s not much to do.
