No connection could be made because the target machine actively refused it?

Question

Sometimes I get the following error while I was doing HttpWebRequest to a WebService. I copied my code below too.

System.Net.WebException: Unable to connect         


        

Answer 1

I've received this error from referencing services located on a WCFHost from my web tier. What worked for me may not apply to everyone, but I'm leaving this answer for those whom it may. The port number for my WCFHost was randomly updated by IIS, I simply had to update the end routes to the svc references in my web config. Problem solved.
