Bot not responding or hangs while started using WCF service but works without any issue using uipath studio

I have executed the bot using uipath studio. My bots functionality is to navigate to an url and validate the data fetched from the excel. All goes fine when executed using uipath studio.
But when the same is done ie started the bot using the WCF service, it hangs up after navigation to the url.
Please help me resolve this.
