LoadCompletePro_4.91.7328.24_No traffic has been recorded error on screen.

Hi Amit,

Actually, you provided extremely little info about your problem. We can guess that by itself your application is working. Otherwise you would have nothing to use to record the traffic.

You did not mention if your application uses http(s) or some other protocol, you did not describe what actual actions were done to make a recording...
Just to be on the safe side and have something to start with: have you followed all steps mentioned in this help section: https://support.smartbear.com/loadcomplete/docs/testing-with/preparing/index.html ?
