Amazon does not allow dots in the name of buckets due to a peculiarity of the SSL setup made for S3 service.
Their certificate is a wildcard SSL, issued for *.s3.amazonaws.com and covers all subsubdomains in the place of *.

If your bucket name contains dots, we would recommend renaming a bucket and removing them.
Should you have any questions, do not hesitate to contact us back.
