 <p>It sounds like there's a network issue preventing you from connecting to your Worklight server.</p> <p>This can be due to many different reasons, to list some:</p> <ul> <li>Poor WiFi/3G</li> <li>Faulty device</li> <li>Firewall issues on the network where the webserver is hosted</li> <li>Worklight server issue</li> </ul> <p>To ensure that you are indeed reaching the server I would suggest using a network sniffer. One tool that runs on Windows is <a href="http://fiddler2.com/get-fiddler" rel="nofollow">Fiddler</a>. </p> <p>Fiddler can be set up as a reverse proxy where your device will be making calls to the proxy. The proxy will then route your request to the web server but it will also log the information so you can view it.</p> <p>If you are on Windows, I would suggest installing Fiddler and following Option #2 of <a href="http://stackoverflow.com/questions/4428680/how-do-i-monitor-all-incoming-http-requests">this answer</a>.</p> <p>You should then be able to see if your requests are reaching the server and continue investigation from there.</p>
