Symptom: Loading Admin Console through the UMP portlet shows only a blank/white page, while navigating directly to the Admin Console works fine.
Environment
Release: Component: CAUIM
Cause
The Admin Console/service_host probe uses a self-signed certificate, and browser security settings frequently prevent the content of the Admin Console from being loaded unless this certificate is accepted/trusted.
To resolve the issue, you must first navigate to the Admin Console outside UMP, and then you must accept and SAVE the self-signed certificate into the Trusted Certificates store.
