This is what happens to me too, except I haven't been fortunate enough to successfully get into the game. I spawn unconscious, I attempt to respawn when I get in it just tells me I am dead. So I join the server unconscious, and respawn in dead.

EDIT: Okay, so after many, many attempts to join servers I finally got in, and after getting in that one time I have been fine to get into servers ever since. Hopefully it doesn't happen again, but if you keep trying eventually it will work. I was attempting to join servers for about 20-30 minutes before I got in.
