I have the Android HA app. It’s set up on 3 phones and login fine. I have an older oppo phone.
When I login, it takes the url, u/pw. Then says cannot establish ssl connection. What does that mean?
Is your phone trying to connect to https://… rather than http://…? I have an old(ish) Oppo, which works fine.
It auto detected https://mydomain which is right. I don’t allow http
My working phones show https://mydomain under HA URL.
