Baldi's Basics Multiplayer Remake Prototype

We have already tried to play with a friend 100 times, but when someone makes a room and tries to come in, even if you made a room with a specific name, then when my friend tries to come in and makes a room himself, this has never happened before; we already managed to play a little twice, but we were crashed or someone temporarily walked away and turned off the game. In short, please help us.
