Receive AccessDenied when trying to refresh a page on my website - S3 and CloudFront

Question

Hello,

For a while, I was simply storing the contents of my website in a s3 bucket and could access all pages via the full url just fine. I wanted to make my website more secure by adding an SSL so I created a CloudFront Distribution to point to my s3 bucket.

The site will load just fine, but if the user tries to refresh the page, they will receive an AccessDenied page.

I have a policy on my s3 bucket that restricts access to only the Origin Access Identity and index.html is set as my domain root object.

I am not understanding what I am missing.

Any help is much appreciated.

Answer

Try these steps to fix the issue:
1. Ensure CloudFront's Origin Access Identity can access all files in your S3 bucket.
2. Check all objects in S3 have the required permissions for CloudFront access.
3. Redirect `404: Not Found` errors to `/index.html` with a `200: OK` response.
4. Check CloudFront Origin Settings: Match the "Origin Protocol Policy" with your S3 setup.
5. Check Viewer Protocol Policy: Set to "Redirect HTTP to HTTPS".
6. Clear CloudFront cache after changes.
