Я пытаюсь подключиться к удаленному серверу sftp через ssh с помощью JSch (0.1.44-1), но во время "session.connect ();" Я получаю это исключение:

Я могу войти на удаленный сервер с помощью команды linux sftp. Я пытался найти какую-либо подсказку в интернете, но мне это не удалось.
Отладка вывода команды linux sftp:
