I just upgraded my OPM from V8 to V9 without any problems but...
I manually had to change the TCP port in the IIS server from 80 to 17777 and
When I try to open the website now I get the following error
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 10.33.1.254:80
