Windows RDP отключается перед установлением соединения в Ubuntu

Я установил xrdp в своей версии сервера Ubuntu 16.04 LTS с помощью xfce, но я не могу войти через компьютер Windows с RDP по умолчанию. Он отображается как подключенный / загруженный, диалоговое окно закрывается и RDP автоматически останавливается.

Вот данные журнала sesman, которые могут помочь.

Я не уверен, в чем проблема. Любая помощь приветствуется, и я новичок в мире Linux / CLI. Если это помогает, этот сервер обновляется с 12.04 LTS до 14.04 и 16.04 LTS.
