Netgear Armor (Bitdefender)

I have setup a website with email for our local village.  Initially accessing webmail from my house was not a problem, until the host changed the name of the server.  Now Netgear Armor blocks the site, claiming it's unsafe.  I followed the procedure to connect to my router via the Android app (!!??), which supposedly would allow me to unblock that site.  However, that option isn't available, even after I removed and reinstalled the app.

Why isn't that option available on the router interface through a web browser?  There should be way to list known safe sites on the router itself, without jumping through multiple hoops that lead no place.

Also, the RAXE290 isn't on the "Associated Products" list.
