Thank you for your response and let me clarify:
Regarding the certificate: I have already trusted the self-signed certificate and I can go to the site by accepting the warnings. I also used a localhost entry to go to the site using the common name on the certificate. This does not clear up the "not secure’ warning and according to the referenced link, it is because the certificate does not have an “alternate name” listed. Frankly this does not bother me and it does not stop me from reaching the firewall web site.
The real issue is with the “Shields Up” toggle which does not allow me to toggle it to “down”. I can slide it about half way to off but it snaps back to on.
