I get an error while rendering a report.

This is my coding in aspx.vb

Dim path As String = "/Reports/EmployeeList"
Dim format As String = "MHTML"
Dim rs As New server.ReportingService

rs.Credentials = System.Net.CredentialCache.DefaultCredentials

Dim parameter As ParameterValue()
Dim encoding As String
Dim mimeType As String
Dim parameterUsed As ParameterValue()
Dim warnings As Warning()
Dim StreamIds As String()

Dim data As Byte()

data = rs.Render(path, format, Nothing, Nothing, parameter, Nothing, Nothing, encoding, mimeType, parameterUsed, warnings, StreamIds)

This is the error message.

System.Web.Services.Protocols.SoapException: The operation you are attempting requires a secure connection (HTTPS). --> The operation you are attempting requires a secure connection (HTTPS).

anybody can help me, thanks.
