Kurento ошибка туториала

Делаю студенческий проект на андроид, нужно реализовать видеосвязь. Выбрал для реализации Kurento. Поставил докер и запустил контейнер. Насколько могу судить сделал это правильно. Далее скачал туториалы с гита. Пытаюсь запустить - выпадает ошибка. Пытался открывать закрывать порты, менять проперти, но ничего не выходит. Прошу помощи. Если есть альтернатива куренто, то я бы рассмотрел. Заранее спасибо за помощь
