I have installed and configured SSRS and when I check the URL via HTTP it works fine (I haven't configured SSL).
When I try to run a report from the Windows application, I get the following error message:
Unable to connect to the remote server
No connection could be made because the target machine actively refused it xxx.xx.xxx.xx:443
But I am not trying to get to port 443, I am trying to get to the default port 80. I'm not sure why the windows application is trying to access port 443.
The Windows application and SSRS is on the same server using the same network. The server is part of a load balancer which has a SSL certificate.
