Panoramic WI Fi app and Iphone wi fi failure

I have had a Panoramic WI FI system for 2 months. The wi fi failed on my 6x Apple iphone after a power outage and reboot of the wi fi. No access to the app either, all frozen up.

Same thing happened on another newer iphone , after downloading the app for access to the system. Both phones show a strong wi fi signal but do not process an internet connection.

Those phones operate normally with other wi fi connections and my other home devices ( Computer, TV's, etc) work fine on the Panoramic system.

Ive tried many work arounds, but phones still do not function off the system.

This all appears to be "app" related.
