Hi,
The url is actually correct, there is some issue with the actual bucket name (it might contain a dot or something).
As we don't know the actual name of the bucket, we cannot say what's the real issue (just don't send us one, privacy)
Ah, yes it does have a dot so that is likely the issue. Still would be nice to have option to use either bucket first, or plain s3.amazon.com domain for other buckets.
