ProFTPd - Невозможно войти в систему, постоянная ошибка 530

По какой-либо причине я не могу подключиться / войти в систему через FTP-клиент или из командной строки к моему FTP-серверу. Я использую Webmin и ProFTPd. Я установил пользователя с простым паролем как часть группы ftp с / sbin / nologin в качестве пути к оболочке. В журналах указывается только «FTP-соединение открыто» и «FTP-соединение закрыто». Указанные мной пассивные порты открыты на брандмауэре.

Как будто пароль неправильный, но это так. Вот мой файл proftpd.conf:
