Отказано в разрешении SSH (публичный ключ, пароль) из Интернета

Я успешно подключаюсь через SSH к своим радиостанциям Ubiquiti (5 из них) через Интернет (DDNS) в течение некоторого времени, но с тех пор, как пару недель назад с теми же учетными данными я не могу, только один из них все еще позволяет мне подключиться, остальные четыре дают мне отказ в разрешении. Я уже менял пароли и номера портов (имя пользователя у всех одинаковое), но безуспешно. Вот мой -v распечатка того, что работает:

Я хотел бы добавить, что из локальной сети я могу без проблем подключиться ко всем из них, используя одни и те же учетные данные. Кто-нибудь может мне помочь?
