I've upgraded my site to use HTTPS. Internal client MP functionality appears to be ok.
However, in the process, I've managed to break the Application Catalog. It starts to load, but the second the silverlight page initialises, it flicks to:
"Cannot connect to the application server" - The website cannot communicate with the server. This might be a temporary problem. Try again later to see if the problem has been corrected. If this problem continues, contact your help desk".
The key piece of information is: "the remote server returned an error (403) Forbidden" which is reported in ServicePortalWebSite.log whenever a client attemps to visit the page.
This is a standalone primary with the Application Catalog roles installed locally.
I tried uninstalling the Application Catalog roles and reinstalled them but it hasn't helped.
Any suggestions?
