Description of problem:
I have a project https://github.com/hhimanshu/tweetstream where I connect to server using websocket, see https://github.com/hhimanshu/tweetstream/blob/master/src/main/webapp/tweets.js#L19. This works fine when I run it locally on my laptop, but I see error when deployed to Openshift

I even tried port :8000, but no luck
var connection = new WebSocket('wss://'+ document.location.host + ':8000' + document.location.pathname + 'tweets');
  connection.onopen = function() {
    connection.send('brazil');
  };
  connection.onerror = function(error) {
    console.log('WebSocket Error ' + error);
  };
  connection.onmessage = function(e) {
    var parse = JSON.parse(e.data);
    var coordinates = parse["geo"]["coordinates"];
    console.log("coordinates:" + JSON.stringify(coordinates, undefined, 2));
  };
