Server error when accessing Changepoint after upgrade: "Value cannot be null. Parameter name: first"

Symptoms

After upgrading from Changepoint to 2017, I get the following error when trying to access the Changepoint website:

Server Error in '/' Application.

Value cannot be null. 
Parameter name: first 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.


Reason

This can be caused by not setting the bindings correctly in the web.config files (The SSL setting on the website must match the bindings configuration for the WCF services).

Resolution

Please check the installation guide for switching Changepoint properly to SSL (or back to HTTP). Alternatively, the binding configuration can be changed in the web.config files using a text editor by following the comments in the files (search for 'endpoint address').
