How do I resolve "403 ERROR - The request could not be satisfied. Bad Request" in CloudFront?

Short description

The error message "403 ERROR - The request could not be satisfied. Bad Request." is from the client. This error can occur due to one of the following reasons:

• The request is initiated over HTTP, but the CloudFront distribution is configured to allow only HTTPS requests. To resolve this issue, follow the steps in the Allow HTTP requests Resolution section.
• The requested alternate domain name (CNAME) isn't associated with the CloudFront distribution. To resolve this issue, follow the steps in the Associate a CNAME with a distribution Resolution section.

Note: This resolution is for troubleshooting the error when you own the application or website that uses CloudFront to serve content to end users. If you receive this error when trying to view an application or access a website, then contact the provider or website owner for assistance.
