When browsing to the Targeting tab in SDL Tridion 2013 SP1 with SDL SmartTarget 2014 SP1 I get the following error, it only appears on HTTPS, the HTTP connection works fine. What could cause this error?

/WebUI/Models/SmartTarget/Services.svc/GetListSmartTargetInstances failed to execute. STATUS (404): Not Found

Investigating the issue a bit further it turns out that the browser cannot load https://server-name/WebUI/Models/SmartTarget/Services.svc/GetListSmartTargetInstances

The WebUI/Models/SmartTarget is part of the SmartTarget extension for the CME. I configured the %TRIDION_HOME%\web\WebUI\Models\SmartTarget\web.config to allow HTTPS as documented in the SDL SmartTarget 2014 SP1 documentation's "Configuring HTTPS" section.

In %TRIDION_HOME%\web\WebUI\WebRoot\Web.config please could you try and set the Tridion.WCF.RedirectTo value to

<add key="Tridion.WCF.RedirectTo" value=""/>

If this works, then I believe its the IIS loopback check disallowing the request.
