"Invalid License Key" and "HTTP Error 503" (4324573)

The Archive Manager 5.0 version of the website will check the license on every request.  This can lead to the error "invalid license key" to be seen in the website log.

This can cause the search grid to not be displayed correctly or not displayed at all in the website and can also prevent other page resources to load such as images or icons.

This can also lead to "HTTP Error 503. The service is unavailable" in the website followed by a crash of the Application Pool in IIS and a 401 error
