R6400V2 firmware V1.0.4.128 port forwarding

Recently I updated my firmware, and now I have lost the ability to access my security system via the web.  It works fine local on WiFi.  I have rechecked the port forwarding settings and they are the same as previously set.  The security system is a web server and is set for static port.  The trigger port “443” shows open.  The web server is set to port “6280”, but does not show as open.  Security system is Resideo home, previously known as Honeywell Tuxedo.
