title: Why websocket don't work on the cloud?
body: <p>I developed our websocket project on wildfly. When we test it on localhost or within our local network, everything work fine. But when I deployed it on AWS, websocket don't work any longer. We can access other html pages. But when we conenct to "ws://ip/project location ", chrome just says hand shake error. I have experienced the same web socket problem on jelastic hosting too. My question is </p>
  
  <ol>
  <li>Why it is happening like this?</li>
  <li>Is websocket protocol not stable enough?</li>
  <li>Is there any suitable hosting for websocket projects in java?</li>
