Which of the following is a cause of this?
The S3 bucket must be configured with Amazon CloudFront first.
The Route 53 record set must have an IAM role that allows access to the S3 bucket.
The Route 53 record set must be in the same region as the S3 bucket.
The S3 bucket name must match the record set name in Route 53.
Explanations:
Amazon CloudFront is not a requirement for routing traffic to an S3 static website. The S3 bucket can directly host static content without needing CloudFront.
IAM roles are not required to grant access to a public S3 static website. The S3 bucket needs to be publicly accessible, but this does not involve IAM roles for Route 53 record sets.
Route 53 and the S3 bucket do not need to be in the same region for static website hosting. Route 53 is a global service and can route traffic to S3 buckets in any region.
The S3 bucket name must exactly match the domain name in the Route 53 record set (i.e.,www.example.commust match DOC-EXAMPLE-BUCKET). This is required for routing traffic properly.
I opine that the answer is:
The S3 bucket name must match the record set name in Route 53.
I estimate that the answer is:
The S3 bucket name must match the record set name in Route 53.
