I am running the latest 1.1.1 HA IOS app on IOS 12 and when opening the app on the same network as my Pi running HA, it shows my local Hom Assistant. If I shutdown wifi on the phone and go to 4G or go to another persons house running wifi (so a different network) and try to enter my Internet IP in the URL (I have a fixed Public IP), so http://xxx.xxx.xxx.xxx:8123 and I have also tried https as well and I have tried this with both a password added as well as no password nothing happens, all I get is a blank white screen. I have tried to enter into the URL the IP address as well as a password and SAVE, but it then comes up with the Connection Error “The internet connection appears to be offline”. Now I have done a port check from the outside world and can see that port 8123 is open and checking my router I can see that the port is definitely forwarded to the correct internal (or LAN) IP for my Pi. Is there something else that needs to be done in the Pi to allow that port to be accepted from 0.0.0.0 I am running the latest downloadable Pi3 Image from the site.
