Mobile App on Android 10,11,12 testet.

If i access the view from my browser iam able to do.
Could someone give a hint, whats worong.

The error message says, that the certificate for has expired.
That’s not related to openhab at all and also happening of I open the website with any browser.

Have you included content from this website (e.g. an image) into your page or how relates the website to your openhab installation?

Details for that what @Matze0211 wrote:
checking the certificate in e.g. firefox shows:

Not Before: Tue, 14 Sep 2021 00:00:00 GMT
Not After: Sun, 18 Sep 2022 23:59:59 GMT

So that means your certificate expired.

Thanks very much.
Solution was a Link to a Picture, i used for a Location.
In the Future i will Download them and Store them on the pi direkt.
