Any idea why?

Hello Scott,

Thank you for your question about this snipe. You didn't win because the seller blocked you. No, we aren't told the reason.

The exact error that eBay returned is: 'Unfortunately, this seller has decided that you are not permitted to bid on their listings. You may contact the seller via the "Ask Seller Questions" feature if you want additional details.'

I hope I have explained this to your satisfaction. Please let me know you need help with anything else.
