Nighthawk AC4000 Router (R8000P)

hi there

I have been running 1st generation circle on the router for years along with the iOS App.  It has now completely stopped not working.

I went ahead and factory reset the router using all defaults settings and still the same problem.

Profiles not working i.e. any site just shows meet circle webpage

Cannot get Text Code to use on another device.

Cannot get Passcode to use on another device

Does not work when I am connected to my mobile network.

I am running the latest version of the firmware V1.4.4.94_1.3.56

Thanks
