SSRS export in reportviewer redirects to the wrong server

My ASP.NET Application and SSRS reports are on different servers. I could be able to show the reports to ReportViewer control.
But, When I try to export the report, It redirects to my application server, not the report server. Hence shows this error.

Quote:

The remote server returned an error: (401) Unauthorized.

The URL of the PDF Export Page is shown as the below. It's supposed to be http://rpt-srv-01/

http://app-srv-01/MyApp/Reserved.ReportViewerWebControl.axd?ReportSession=exndkq453f3ugmmukx1kzq55&Culture=1033&CultureOverrides=True&UICulture=1033&UICultureOverrides=True&ReportStack=1&ControlID=0a4973dfd17142b7b113aa602270b424&OpType=Export&FileName=ClientInvoicePrint&ContentDisposition=OnlyHtmlInline&Format=PDF

What I have tried:

I am assigning ReportServerUrl and ReportPath to the reportViewer to set the servername and reportpath. But it doesn't seems to work.

ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
   ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://rpt-srv-01/ReportServer");
   ReportViewer1.ServerReport.ReportPath = "/MyReports/Quotes_Invoices/ClientInvoicePrint";
   ReportViewer1.ServerReport.Refresh();
