[Gameplay] connection errors in multiplayer

[Arthorias]

While trying to play multiplayer, my partner often can't connect. We use Steam connection. It tells him "no friends playind grindea" or "playing a different version". Sometimes it justs works. We uninstalled the game and reinstalled it. The problem is still there. I'm always the host. We tried using 4G and in different houses, same problem. He gets the steam notifications that i'm playing but in-game : not there. It gets really frustrating, as it sometimes also disconnects while we're playing
