SQL Server Data Tools Giving Error "The request failed with HTTP status 404: Not Found."

Hi, I am using Server reports in my application. I am using SQL server 2012 with visual studio 2102. I successfully configured the report service and I am able to open report manager through browser. 

I created a report from report builder (in browser), and when I am opening this report it opens..!

My Report Server URL Is: http://adil-pc/Reports/

Report created from report builder location is : /Reports/Untitled

But when I am calling this report through my ASP.net application, it is giving me error

"The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.

• The request failed with HTTP status 404: Not Found."

I am using following line of code to show the report in my ASP.net application,

<rsweb:ReportViewer ID="ReportViewer1" runat="server" ProcessingMode="Remote"><ServerReport ReportPath="/Reports/Untitled" ReportServerUrl="http://adil-pc/Reports/" /></rsweb:ReportViewer>

Please help me,  I have stuck here.... 

Thanks In Advance....
