Hi,
My HA setup was running perfectly then I switched Internet providers and got a new router.
I have the companion app installed on 3 phones, all android. My own, my sons and my wifes.
Mine and my wifes work perfectly just as normal.
My sons will only connect when on the home WiFi… However I have only input my external duckdns address… Not the internal one…
So why would one phone not connect when 2 do? And why will it connect to the external address but only using home WiFi?
I’m so confused… Any help on where to even start diagnosing this is greatly appreciated
