You have just deployed a website that utilizes CloudFront, ELB, and S3 to serve content. When users access your site, they are seeing broken image links. You know you configured CloudFront to use cdn.yourdomain.com. What is the most likely reason why your users not seeing the images?

  1. There is no rule in your bucket policy allowing public access.
  2. The images in S3 are saved as .png instead of .jpg.

  3. A VPN to the IP addresses specified in the AWS official S3 prefix list
