Не удалось подключиться к отсрочке (async (tcp: // ip: 5044)): набрать tcp ip: 5044: тайм-аут ввода-вывода

Наконец, я обнаружил, что это вызвано провайдером VPS aliyun, он открывает только общий порт, такой как 22, 80 443.

Мне нужно войти на страницу управления aliyun VPS и открыть 5044, чтобы провайдер VPS обходил порт 5044.

* Примечание. * Вложение: некоторые другие проблемы, с которыми я столкнулся, когда config filebeat с ELK.

** Проблема 1: ** Не удалось подключиться к отсрочке (async (tcp: // ip: 5044)): dial tcp ip: 5044: connect: соединение отклонено
