Error "An error occurred during validation of Enterprise Server settings"

Background

Errors can occur in Meridian Configurator and PowerUser where TLS 1.2 is used.

Description

When Meridian Configurator and Meridian PowerUser connect to Meridian Enterprise Server an error can occur if TLS 1.2 is the only protocol in use.

Meridian Configurator

An error occurred during validation of "Enterprise Server" settings.

An error occurred while receiving the HTTP response to 'https://<hyperionserver>/bcenterprise/Services/ConfigurationService.svc'. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

Meridian PowerUser

An error occurred while making the HTTP request to https://<hyperionserver>/bcenterprise/Services/ConfigurationService.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.
