index.html errors

Hi there - I have created a small test Rise 360 course and exported to Web. 

I have created an Amazon S3 account and added all of the unzipped files and folders to a public bucket.

When I click on the url for the index.html file, I am getting the following error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Code>AccessDenied</Code>

</Error>

Any ideas? I couldn't get it to work in Google Cloud either.  It does run in Review 360 but I really would like to embed an example course to my website so I can't link through to the Review link.

Thank you.
