The problem was with proxying through Nginx. I had to change the Nginx proxy configuration as follows.

upstream app_xxx {
   server 127.0.0.1:3000;
}

server {
   listen 80;

   location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_pass http://app_xxx;
   }
}

The important thing is: The real IP is in the X-Real-IP parameter. So you have to access it as:

env['X-Real-IP']
