Unable to view system reports - error 'The page cannot be displayed' inside Internet Explorer

Troubleshooting

Problem

User attempts to run a standard report (also known as 'system report') inside Controller. The expected (Internet Explorer) window appears, with the initial message 'Please wait, loading the report...'. However, instead of the report appearing shortly afterwards as expected, the screen hangs on this message or alternatively is followed by an error message.

Symptom

The exact error message will vary according to environment (client's Internet Explorer version, server's IIS webserver version) but one example is:

The page cannot be displayed
