How to use websocketpp server with client that not using websocketpp library?

[vasnhnloc]

I made a server using websocketpp on linux, and when I connect to clients that are not using websocketpp such as Hercules, QtCreator, the client inform that it is connected, but 5 seconds later, the connection time out occurs and on the server side, the console appears
"[fail] WebSocket Connection [::ffff:192.168.0.104]:61667 - "" -0 websocket:22 the opening handshake timed out.
All the example server code on the github repository come with the same result.
But when I run server and client using websocketpp, the connection is establish successfully.

So how can I connect the websocketpp server with QtCreator or a javascript client?
Thank you in advance.
