my s3 bucket static website can not accessed, Bucket website endpoint 400 Bad Request

Because your bucket is encrypted with customer-managed keys, I think you will have trouble serving it this way.

However, a better way to create a static website with customer-managed keys is to use an Amazon CloudFront distribution for the bucket. This blog describes how to use CloudFront origin access control to serve a website from a bucket that is encrypted with customer-managed keys: https://aws.amazon.com/blogs/networking-and-content-delivery/amazon-cloudfront-introduces-origin-access-control-oac/

I make sure that my bucket use AWS managed keys, not Customer managed keys

and all objects inside my bucket don't use any encrypted keys and inherit my bucket.

I not only review you says blog, but also review s3 and cloudfront official docs step by step. s3 don' t work, cloudfront don't work too.

please help me. what's wrong?
