Guys,
I’ve just migrated my HA installation from pi3b+/microsd to pi4b/SSD.
It basically works perfectly with the following exception: if I try to reach my duckdns address via home wifi, HA won’t show up but, if I disconnect from my SSID and try via mobile network, it does…
Internal LAN IP (https://192.168.1.XXX:8123) does work as well.
I guess the problem is related to the router, rather than to HA installation, but actually didn’t change any setting to it.
If you have any idea, please just let me know because I’m getting crazy.
Cheers
