events {
 worker_connections 1024;
}
http {
 include  mime.types;
 default_type application/octet-stream;
 sendfile  on;
 keepalive_timeout 65;

  location / {
  proxy_redirect off;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_pass http://47.92.69.112:8080;
  }
 }
