duping not working today

normally, i am extremely good at duping...but today even if I think i did it very well, it stays on connecting for like 10 seconds before finally loading! I have no lagg or anything and i go to a slow server to ensure i can create lagg. Can anybody give any ideas as to why this may be happening?
