Hello Jim
I tested it in Review and Amazon S3 and it works for me.

I also tested it on my Google Pixel and it works.
You can try my link to see if you have the same issue.
Others who know more about AWS or how you built your web object may have other ideas since it's outside the scope of Storyline.
I'd assume there's some sort of security or permissions issue. Since it's running from AWS, I'd connect with the community there and see if they have any ideas or help.
