I have a question, when I try to load hass in a browser on my tablet or phone it fails to load. The answer I got is no connection while they both have an internet connection. The browser on 2 latops are operating as expected.
I understand that your’re also trying to access your HA from outside your network? Can you access from inside your network using your internal IP of HA? Can you access from outside using your WAN IP of domain?
Did it worked before? Maybe your ISP changed your IP so your domainname is not forwarded to the correct IP?
