It looks like your bid was too low due to eBay's bid increment system:
https://www.myibidder.com/login/faq/4/#q14 Your bid would not be accepted even if you bid manually the same amount on eBay directly.
Also, I see you used 1 second snipe which is not recommended. The recommended value is about 5-6 seconds.
If you lower the time, you accept the risk for your snipe to have a higher chance to miss due to possible network lags.
