Custom SSL Domain Names and Root Domain Hosting for Amazon CloudFront with www and without

i'm having some difficult to use my domain with HTTPs with cloudfront + s3 bucket

I follow this 3 posts:

The problem is that the site does not open with www when i create the CNAME .mysite.com and point to the cloudfront distribution, and when i edit to www.mysite.com, the site opens with www but doesnt without the www.

Maybe i'm missing something? I follow the exactly steps in the tutorials, i can't see where where is the mistake.

The error is 404 - not found. I already try several configurations, i already try to ask support for AWS and didn't work, i already try to use a wildcard and nothing works.. nothing!. I really don't know what to do.

I'm running a ember.js app in the bucket, and i was using ember-cli to develop.

Thanks in advance.
