I can't view the files in my web distribution.
If you cannot view file in your CloudFront web distribution, the following topics describe some common solutions.
Did you sign up for both CloudFront and Amazon S3?
To use Amazon CloudFront with an Amazon S3 origin, you must sign up for both CloudFront and Amazon S3, separately. For more information about signing up for CloudFront and Amazon S3, see Getting Started with CloudFront.
Are your Amazon S3 bucket and object permissions set correctly?
If you are using CloudFront with an Amazon S3 origin, the original versions of your content are stored in an Amazon S3 bucket. The easiest way to use CloudFront with Amazon S3 is to make all your objects publicly readable in Amazon S3. To do this, you must explicitly enable public read privileges for each object you upload to Amazon S3.
If your content is not publicly readable, you need to create a CloudFront origin access identity so CloudFront can access it. For more information about CloudFront origin access identities, see Using an Origin Access Identity to Restrict Access to Your Amazon S3 Content.
Object properties and bucket properties are independent. You must explicitly grant privileges to each object in Amazon S3. Objects do not inherit properties from buckets and object properties must be set independently of the bucket.
Is your alternate domain name (CNAME) correctly configured?
If you already have an existing CNAME record for your domain name, update that record or replace it with a new one that points to your distribution's domain name.
Also, make sure your CNAME record points to your distribution's domain name, not your Amazon S3 bucket. You can confirm that the CNAME record in your DNS system points to your distribution's domain name. To do so, use a DNS tool like dig. (For information about dig, go to http://www.kloth.net/services/dig.php.)
The following shows an example dig request on a domain name called
and the relevant part of the response. Under
ANSWER SECTION, see the line that contains
The CNAME record for your domain name is set up correctly if the value on the right side of CNAME is your CloudFront
distribution's domain name. If it's your Amazon S3 origin server bucket or some other domain name, then the CNAME record
is set up incorrectly.

For more information about CNAMEs, see Using Alternate Domain Names (CNAMEs).
Are you referencing the correct URL for your CloudFront distribution?
Make sure the URL you're referencing uses your CloudFront distribution domain name (or your CNAME), not your Amazon S3 bucket or custom origin.
Do you need help troubleshooting a custom origin?
If you need AWS to help you troubleshoot a custom origin, we will probably need to
X-Amz-Cf-Id header entries from your requests. If you are not already
logging these entries, you might want to consider it for the future. For more information,
see Requirements and Recommendations for Using Amazon EC2 and Other Custom Origins.
I can't view the files in my RTMP distribution.
If you cannot view the files in an RTMP distribution, are your URL and your playback client correctly configured? RTMP distributions require you to use an RTMP protocol instead of HTTP, and you must make a few minor configuration changes to your playback client. For information about creating RTMP distributions, see Task List for Streaming Media Files Using RTMP.
Error Message: Certificate: <certificate-id> is being used by CloudFront.
Problem: You're trying to delete an SSL certificate from the IAM certificate store, and you're getting the message "Certificate: <certificate-id> is being used by CloudFront."
Solution: Every CloudFront web distribution must be associated either with the default CloudFront certificate or with a custom SSL certificate. Before you can delete an SSL certificate, you need to either rotate SSL certificates (replace the current custom SSL certificate with another custom SSL certificate) or revert from using a custom SSL certificate to using the default CloudFront certificate. Perform the procedure in the applicable section:
