This topic describes the cause of the "You are forbidden to list buckets" error returned when you access the accelerated domain name that is mapped to a bucket and the solution to the error.

Problem: When you access the accelerated domain name that is mapped to a private bucket for which CDN back-to-origin is enabled, the You are forbidden to list buckets error is returned.

CDN

Cause: AGetBucket (ListObejcts) request is sent to CDN. By default, this request is denied by CDN.

Solution: Rewrite the URL of the accelerated domain name in the CDN console to redirect the URL to a file in the path specified by the URL. For example, if the URL of the accelerated domain name that is mapped to your bucket is example.aliyundoc.com, rewrite the URL to example.aliyundoc.com/index.html.
