error/local hub/cannotregisternotavailablesite

From MoodleDocs

To register to a hub your Moodle site needs to be accessible by the hub so the two can communicate bi-directionally.

The error indicates that the hub could not reach your site.

Reasons why you may have seen this error:

  1. Your site has a local address like http://localhost or
  2. Your site is protected by a proxy or firewall
  3. The hub is being prevented in some other way from accessing your site - for example you have restrictions on certain IP addresses, one of which might be the hub.
