title: Client can connect and send message to Ratchet but can't receive from server
body: <p>i have a web application which communicates with server via websockets. I am using Ratchet as a websockets server.
  On localhost i'm using <code>XAMPP (Apache 2.4.10 and PHP 5.6.3)</code> and everything works beautifuly. On my VPS i'm running Debian 8, Apache 2.4.10, PHP 5.6.7 and i have a problem with server to client communication. Ratchet is running at port 8080.</p>
  
  <p>Clients can succesfuly connects to Ratchet (via <code>ws://ipOfServer:8080</code>) and send him a message (ratchet will print it), but when Ratchet sends message to client, nothing arrived at client. </p>
  
  <p>I've tried enable Apache module mod_proxy_wstunnel and add <code>ProxyPass "/wsc/" "ws://ipOfServer:8080"</code> to my domain config. Clients now connects to Ratchet via ws://ipOfServer/wsc, and its the same story as without using proxy.</p>
  
  <p>Can somebody please help me, how to get running it? Thakns</p>
