Hi Nagakula,
Do you have Internet access on the VuGen machine you are trying to record from?
LoadRunner machine can be used as a proxy only after you have stared recording in proxy mode.
Please make sure that you have started recording on the VuGen machine before trying to access a web page from the mobile device. If VuGen has started, on the VuGen machine the floating recording toolbar should appear.
You should start the application from your mobile device. Vugen will not start it automatically.
Additional information for proxy recording is available in the following posts:

Kind regards,
