Hello Ian,
Thanks for your message. You can go to your Completed tab. There, you will find the bid placement times, and there is also now a "log" icon. If you click that, you will be presented with a full log of the snipe from the time it was entered, to the time it was executed.
We do know from the log that multiple snipes were placed from multiple locations, and all bid attempts returned the same result.
In your case, eBay says the token was revoked. We check for it every 8 hours and send email if we find it has been revoked. So this must have happened within 8 hours of the bid.
There are three main reasons this can happen.
1. If you revoke it. Probably not the case here, or you would have mentioned it.
2. If you change your password, it invalidates the token.
3. If eBay sees a security concern, they will invalidate the token.
If it isn't one of the above, you have to write to eBay.
Please let me know if I can help with anything further.
