Не удается подключиться к dockerized redis на Heroku

Question

Я новичок в Heroku. Я пытаюсь развернуть образ Docker для Redis на Heroku и хочу использовать его для тестирования своего приложения. Я могу развернуть образ Redis, Redis запускается на Heroku. Я могу увидеть это через:

heroku logs --tail

Проблема в том, что я не могу подключиться к экземпляру Redis. Всякий раз, когда я пытаюсь подключиться к URL-адресу и порту, предоставленным Heroku через redis-cli, он ничего не выводит на консоль. Пожалуйста, помогите мне с моей проблемой.

Вот конечные строки 'heroku logs --tail':
