Just look at the screeny:

Did you just exit a game and try to join that one without refreshing the servers? I don't think they refresh when you are in a game. That may be it.

I had just pressed the "Request Server" button...and i tried again like 3 times.

Hmm...maybe it was laggy. Or maybe it had bots in it?

Nah, bots dont count as players.

The server probably just crashed.
Same happens to our SN public sometimes, It just gets stuck on a certain ammount of players and nobody can join anymore :/

I dont think bots count.
