S3 Service API: Invalid resource type Error

Hey there,

I am running into issues with a files and database backup where it the backup is unable to transfer to Amazon S3.

Here is snippet of the error from the log:

ERROR: S3 Service API: Invalid resource type

The amazon credentials work with just a database backup. This error only appears when trying to do a files and database backup.

I have a feeling it might be something server side, the host this site is on mentioned there is a firewall, but I am unsure if that is relevant or not.
If it is something with the port, the host just want to know if there is specific port needed for S3.

Thanks
