Error 10051

This error indicates that the source URL is missing a required authority component.

Common causes

This error occurs when the source URL of a URL redirect does not include an authority component (for example, http:///path, without a hostname), which is mandatory.

Resolution

Add an authority component to the redirect source URL (for example, include a hostname). Refer to Supported URL components in Bulk Redirects for details on the required URL components for redirect source URLs.
