receiving incorrect url from amazon s3 module
You need to create a group permission for Amazon S3 in Amazon IAM and indicate who can view the bucket.

Instructions on how to grant access to your bucket here: http://blogs.aws.amazon.com/security/post/Tx3VRSWZ6B3SHAV/Writing-IAM-Policies-How-to-grant-access-to-an-Amazon-S3-bucket

Hope this helps.
