I think the issue is not abt bidding in the last secs. I think the problem is abt getting disconnected after being idle for a few minutes. It happened to me a few times too in my laptop. I bid on a player with plenty of time to spare. I watch tv or do other stuff to wait for knockout round. It doesn't happen. I got disconnected. When i refresh it takes more than a minute. So i lost in the bidding.
