While downloading excel file in IE browser getting an error "The connection with server was reset"

Question

Hello,

I am exporting the excel file by passing the datatable.
I am using Handler file in asp.net.
All browser it is working fine but only in IE getting an error.

"The connection withe the server was reset"
I am using the EEPlus libreary i.e :using OfficeOpenXml;
I have some code like:
 context.Response.ClearContent();
        context.Response.Buffer = true;
        context.Response.Charset = "";
        context.Response.ClearHeaders();
using (ExcelPackage excelPackage = new ExcelPackage())
        {
            ExcelWorksheet wsExportOrder = excelPackage.Workbook.Worksheets.Add("Export Orders");


            //Load the dtExportOrders data table into the sheet. 
            wsExportOrder.Cells.LoadFromDataTable(dtExportOrders, true);


            string fileName = @"Export Orders.xls";
            //Write it back to the client
            context.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
           
            context.Response.AddHeader("content-disposition", "attachment;  filename=\"" + fileName + "\"");
            context.Response.BinaryWrite(excelPackage.GetAsByteArray());
            context.Response.Flush();
        }
       
        context.Response.End();
