You should be able to find the reason the seller GAVE for the cancellation on the Bid History Page, in the section on cancellations and retractions below the main history (but eBay keeps reformatting things, often with a loss of some functionality). Note that one cancellation removes all bids that bidder placed on that auction, though information on only 1 bid will be displayed. You need to be logged in under the same ID you bid with, as only the seller and the particular bidder are allowed to see the reasons.
Go to the Listing Page for the auction (the one with the Description and the Shipping and Payments tab) and from there click on the # of bid display (even if "0 bids", but see below if it is) to get to the Bid History Page. BUT FIRST, if the auction is completed and there are "0 bids", look in the upper left to see the reason the seller GAVE for ending the auction early (and if that is the case it is extremely likely that the reason for your bid being cancelled is that the seller cancelled all bids to end the auction early.
