I needed to add the net.tcp binding to the binding of the application in IIS.
Right click the virtual directory/application in IIS -> Manage application -> Advanced settings.
In the Enabled Protocols part I just added net.tcp.
I got this problem while working on AX 2012 R2 Retail Real Time service on Windows Server 2012 with IIS 8
