Bounced out of lobby

Why the F does it time you out in the lobby??? I sat in the lobby waiting for enough players and when finally enough showed up I get bounced!!! WTF! Should be no time out, if I want to wait 30 min for a lobby to fill up i should, who gives an F!  Then I couldn't get back into the match and had to sit in more lobbies waiting for more players!! Infuriating
