I am trying to install SQL Server 2012 Reporting Services on Windows Server 2008, but all the web interface says after adding the feature and confirming all the default settings in Reporting Services Configuration Manager is
Error: Unable to connect to the remote server
In the logfile there is this message:
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:80
This worked just few months ago on the same system.
