Thank you for your KB post. PRTG actually does not use IIS. So it seems the Enterprise Console connects to an IIS webserver, which is also running on this machine.
On which IP & Port combination can you connect to the PRTG webinterface with your browser?

Please verify the connection settings of the Enterprise Console, so that they match this.
