A recent notice has been posted by Google regarding a security feature that restricts users from accessing Google Maps directly. However, this restriction only applies to external links and not the map itself.
For users who have clicked on this external link, they will be redirected to the map's location information page.
The 400 Bad Request status code is a generic HTTP error response indicating that the request could not be processed due to a known problem with the server. In this case, the restriction only applies to external links and does not affect access to the map itself.
