Исправление 500 внутренних ошибок сервера в диспетчере устройств OSX

Для начала я бегу OS X 10.11.6 (Build 15G19009)и мой сервер есть Server 5.1.5 (Build 15S7047). Я пытаюсь зарегистрировать компьютер, используя раздел диспетчера устройств, когда я нажимаю Enrollкнопку, я получаю 500 внутренних ошибок сервера. Погуглив, я обнаружил, что это очень распространено, и что нет "верного" способа исправить это. Просматривая мои файлы журнала, я обнаружил следующие ошибки:

Из того, что я обнаружил в этом вопросе, эти ошибки, похоже, не соответствуют решениям. Кто-нибудь знает, что я могу сделать здесь?
