Reverse Proxy NGINX and Foscam Active-X error

Hi All, I have a working reverse proxy for my Foscam out door camera with a StartSSL cert and everything works fine but If I want to use the camera's full function to record to a network device I need to use IE and Active-X....Ewwwww!!! right???

The issue I'm encountering is that when I get to the login page of the camera I have 3 options. Active-x or server push or mobile.

if I choose Active-x I can login but then an error pop-up shows up saying couldn't connect to device.

Any Ideas?
