I, too, am new to the Forum and have been receiving the same error,The server returned a non-200 status code - (403). , when using the link as provided from Amazon Cloudfront. When I add the actual name of the file I receive The server returned an unsupported content type. Was expecting 'application/rss+xml', 'text/xml', 'application/xml' or 'application/json' but received 'video/quicktime'. There are no other choices provided in my AWS bucket for this content. I'm sure I'm missing a vital step in here but haven't been able to find anything online. If anyone could point me in the right direction I'd greatly appreciate it!
