В jsmpp java-библиотеке отдельно привязка на Rx & Tx не работает

Question

Я запускаю простую программу Java, которая использует библиотеку Jsmpp на Binding Rx & Tx отдельно.

В Rx я не получаю DLR, и Tx успешно может опубликовать сообщение.

Кто-нибудь может мне помочь, что здесь не так? почему я не получаю DLR?
