Hi Matt, this website will guide you through adding cdf to your trusted sites on your browser. This laptop must be using a different browser or version than your other devices.

Google is trying to force that all websites are encrypted and this is only the beginning of their push.

PS; I just recalled that I used to see that same error once in a while (long ago when I used Chrome), cdf worked on some devices and not others. The fix was to restart my modem. If you ever get tired of being protected from yourself by Firefox and or Chrome, Vivaldi browser never kills my add-ons or protects me from myself. :-)
