Я пытаюсь использовать ActionCable в рельсах 5, но не знаю, почему он не работает.
В консоли браузера я получаю:
Ошибка подключения WebSocket к ws: //my.website/cable: WebSocket закрывается до установления соединения.
Ошибка подключения WebSocket к ws: //my.website/cable: ошибка во время рукопожатия WebSocket: неожиданный код ответа: 502
Uncaught TypeError: невозможно прочитать подписки на свойство undefined
Я установил Passenger + Nginx

У меня есть Integrated Action Cable с Passenger + Nginx благодаря этому руководству: Интеграция Action Cable с Passenger + Nginx
Итак, nginx + пассажир работает нормально, так как приложение подключено к сети.
