I am using an Arris BGW210-700 modem/router from AT&T. I have setup DuckDNS correctly for my HA instance and can access it without any issues when I am outside of the network my HA is running on.
However, when I am on my local network, I can only connect through the local IP address, 192.168.1.x. If I try to browse to HA via the DuckDNS url, I get a page returned with the HA logo and the message “Unable to connect to Home Assistant.”
If I look at the developer tools console, I see this error message “https://mydomain.duckdns.org:8123/auth/token 400 (Bad Request)”.
My understanding is that this is an NAT loopback issue but that the Arris BGW210-700 doesn’t support that. I was wondering if anyone out there had experienced something like this or had any ideas on how I can work around this? The biggest issue being that I can’t access HA via the iOS app when I’m at home without first turning Wi-Fi off.
