What may be the problem if the KTM Thin Client error - Connection to server is broken

Issue

What may be the problem if the KTM Thin Client errors with:

Connection to server is broken

Solution

NOTE: This error is generic and this is a solution for one possible cause of the error.

This specific cause will write the following exception to the event log:

System.ServiceModel.ServiceActivationException: 
The service '/KTMThinClientServer/AuthenticationService.svc' cannot be activated due to an exception during compilation.
The exception message is: This collection already contains an address with scheme http.
There can be at most one address per scheme in this collection.
Parameter name: item. ---> System.ArgumentException: This collection already contains an address with scheme http.
There can be at most one address per scheme in this collection.

The problem is an invalid IIS configuration. To fix this, open up the IIS Manager snap-in and right-click on the Default Web Site and select Properties. On the Web Site tab in the Web Site Identification section, click the Advanced button, which should bring up the Advanced Multiple Web Site Configuration dialog box.

There should not be more than one entry in this dialog for the same port.
