Honestly it is a bit ridiculous. When I've managed to get past the 2002 lobby errors at all, I've got into a 3500+ queue and around 2700 it errors out, and I have to log back in and start all over again. In between the lobby errors, I've sat in the queue now 4 times (for an hour or more each time) and have errored out each time. I'm fine with waiting my turn in a queue, but if the queue always fails and you just keep starting over, it needs to be addressed.
