Error installing Visure Reviewer : “There was a problem with your request”

When installing and configuring Visure Reviewer you may face the following error message:

This error is caused by a wrong url specified the appsettings.json file (C:\inetpub\wwwroot\VisureReviewer\)

"ServerBaseUrl": "http://localhost/VisureAuthoring",

and the settings.json (C:\inetpub\wwwroot\VisureReviewer\wwwroot\assets). 

"apiUrl" : "http://localhost/VisureAuthoring/api/v1",

localhost in both examples should be replaced by the FQDN of the server that can be accessible to the end-users.

Edit both files to reflect this and restart the website within IIS Manager.
