title: Geospatial Analytics - MQTT connection issue on BlueMix
body: <p>I completed the following tutorial:
  <a href="http://www.ibm.com/developerworks/library/mo-monitordevices-app/index.html" rel="nofollow">http://www.ibm.com/developerworks/library/mo-monitordevices-app/index.html</a></p>
  
  <p>Next, I launch the app on BlueMix and click on the geo-starter Visualizer link. It launches the screen but I cannot see any of the connected devices on my screen. See screenshot of debug mode in browser. It seems like I am unable to connect to the MQTT server from my environment. This looks like a possible issue with the firewall on my network. </p>
  
  <p>Couple questions:</p>
  
  <ol>
  <li>How do I debug this further to determine if this is a firewall issue or something else?</li>
  <li>The MQTT server seems to communicate via port 1883 as per instructions to the MQTT server url, see below:
  mqtt1.m2m4connectedlife.com:1883
  If my network is potentially blocking this port, is there an alternative port I can use such as port 80 to communicate with the MQTT server?</li>
  </ol>
  
  <p>Would greatly appreciate any feedback on this!</p>
  
  <p>Thanks!
