Redis воспринимает легитимные соединения как атаки — возможно, из-за обратного прокси-сервера?

Question

Я использую Redis для использования с Rails и Action Cable. Все они находятся за обратным прокси-сервером Nginx. В настоящее время, когда Redis подключается, я получаю

# Possible SECURITY ATTACK detected. It looks like somebody is sending POST or Host: commands to Redis. This is likely due to an attacker attempting to use Cross Protocol Scripting to compromise your Redis instance. Connection aborted.

Возможно ли, что это вызвано настройкой Nginx? Вот конфигурация, если так:

server {
       server_name "###";
                                                                                                                                                                                    location / {                                                                                                                                                                          proxy_pass http://127.0.0.1:3000;                                                                                                                                            proxy_set_header  X-Forwarded-Proto $scheme;
