Hi Chuan,

it seems to me that you're experiencing exactly the same problem, as you're trying to connect with lightstreamer server from a web page without using the setDomain call correctly.

Please check the HOW_TO_DEPLOY_ON_YOUR_WEB_SERVER.TXT file available in the Lightstreamer distribution under pages/demos/, it will guide you step by step on the deploy of a lightstreamer web application on an external web server.

HTH.
