From MoodleDocs
You are trying to register a site with a url that was previously used by another registered site. A request to register this url has already been sent to the site administrator of this other site. This administrator (probably you) need to confirm the new registration.
As with any problem registering or updating your registration, if you need help, please email support@moodle.org.
