Плагин rabbitmq-mqtt - не может разобрать кадр для подключения

Question

Я пытаюсь установить соединение между NGINX proxy_pass, идущим к плагину rabbitmq-mqtt, и, похоже, возникают проблемы при разборе на стороне mqtt.Вот мои конфигурации и журнал

Конфигурация Nginx:

location /mqtt {
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_pass http://rabbitmq;
    proxy_http_version 1.1;
    proxy_set_header Upgrade    $http_upgrade;
    proxy_set_header Connection "upgrade";
}

Журнал Nginx:

И, наконец, журнал rabbitmq:

Есть ли какие-либо ошибки в конфигурации nginx?
