Your service's server must respond to each callback request with the HTTP status code
200 OK. If there is no response within 3 seconds, a timeout will occur. Kakao checks only the HTTP status code to determine whether the request is successful.
If your service's server does not respond to the callback requests longer than a month or errors frequently occur, each callback setting will be turned to [Disabled] until being enabled again.
