Reverse proxy settings crashing ML Server

I have a few IP cameras I'm attempting to expose externally via reverse proxy. I've created a site on my Mini ML Server and password protected it under a subdomain. This allows me to drop my own custom UI on the camera controls so they work better with my iPhone etc. It's working great on my laptops local virtual host. However, the reverse proxy settings seem to kill apache on the ML server. If I remove the lines in blue below, it seems to work, but i get double authentication requests. Anyone have any experience with this? My Apache knowledge is minimal at best 😟
