We have a web map set up for use in ArcGIS Explorer. The data is hosted on an ArcGIS Server, which is configured to use https only. We can access the secure content over the web browser on a PC on our internal network. However, when using the Explorer app I get a "No Certificate found..." error message with the rest URL of the hosted data. This error message occurs when connected through VPN or on corporate WiFi.
Does the app support HTTPS connections?
When connecting through HTTP it prompts the user to login.
