Logged on a few mins ago,
can't seem to auto create game or manual create one as I always get the same error message,

any idea?

Try not using reserved or profane names

Happened to me also. Restart, join lobby games, and then try creating a game.

Just close the game and open again worked for me. Had the same error yesterday tho.

It wouldn't allow me to create games a few days back, just close reopen lol.
