Hi guys,

We set up a basic reverse proxy configuration (that you can find below this thread).
Our main app is using websocket, and the reverse proxy works fine when no using SSL.

But when SSL is enabled, we noticed a big performance issue making our app very slow. Moreover, the most important: we get a problem when reaching the 50th websocket alive connection for a given user: it crashes our app.

Could you help us finding what's wrong in the following?

App server conf:
- ubuntu v.14.10

Nginx server conf:
- nginx v1.9.0
- ubuntu v.14.04

and the conf file is the following:

###################################

user nginx_user nginx_user;
daemon off;
worker_processes 2;

pid logs/nginx.pid;

events {
worker_connections 1024;

}
}
}
