Amazon Download Potential Risk

I have hosted my member-only download pages on Amazon S3 as described in this video:

the download link is this one :

But when I try to download it, I get this warning message from Firefox :

You understand that it can’t be ok.

What’s the fix for this?

Is this still a problem (I notice 13 days has passed since it was submitted)?

If it is still a problem can you tell us if you configured s2member to access S3 directly or via CloudFront.

If I were to guess what your problem is it would either be a SSL certificate issue if via CloudFront or a CORS issue if accessing S3 directly.
