ReportViewer control not connecting to the report server - Connection refused

Question

I'm having an issue with connecting to SQL report server using the ReportViewer control.  Thing is when I connect to the reporting services web service (http://10.3.27.80/ReportServer/ReportService2010.asmx)
it works fine and I can successfully pull the data I need.  But when I use the web control, its then that I cannot connect.  Here's my code:
ASP.net code:
<%@ Page Title="Reports" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Results.aspx.cs" Inherits="RSReportViewer.Results" %>
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<rsweb:ReportViewer ID="ReportViewer2" runat="server" Width="90%" ProcessingMode="Remote">
<ServerReport ReportServerUrl="http://10.3.27.80:80/" />
</rsweb:ReportViewer>
Error message:
ConnectionRefused
Inner Exception: No connection could be made because the target machine actively refused it 176.74.176.178:8080
I have not got the IP signified above configured anywhere throughout my solution!  So not sure where its getting that in the message.

Thanks in advance for any pointers!

Hi rmccabe82,
Generally, “actively refused it" means that the host sent a reset instead of an acknowledge when you tried to connect. As per my understanding, the issue can be caused by the process that is hosting the service is not listening on that port, this may be
because it is not running at all or because it is listening on a different port. Please try to ping ‘netstat –anb’ (requires admin privileges) to verify that it is running and listening on the expected port.
Furthermore, please make sure the user has permissions to access the report server.
