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 came across this error and took some time to resolve it. In my case I had https and net.tcp configured as IIS bindings on same port. Obviously you can't have two things on the same port. I used netstat -ap tcp command to check whether there is something listening on that port. There was none listening. Removing unnecessary binding (https in my case) solved my issue.
