On my both ipads I have location services disabled. The HA app did work for more than two years but since version 2021.12.1 I have to enable location services. Otherwise I get a Webhook error or a 400 Bad request error. There are no specific errors in the logs. Is this a bug in this version of the app?
After changing the NGINX config it worked again. Nevertheless it’s unclear to me why location services affect this issue. On both ipads and on my iphone the behaviour was the same.
