iOS device model, version and app version

Model Name: iPhone 13 Pro and Apple Watch Ultra 2 Software Version: Newest (18.1.1 / 11.2) App version: 2024.12.2 (2024.1058)

Home Assistant Core Version 2024.12.5

Describe the bug The push notifications on my Mac and my iPhone shows images and video streams in Push notifications. But my Apple Watch shows "Fehler beim Laden des Anhangs. URLSessionTask failed with error. An SSL error has occurred. [...]". All my devices are on my WLAN and the Home Assistant Server runs on http. When I activate the Nabu Casa Home Assistant Cloud, my Apple Watch shows the images in the Push Notifications. In the iOS Companion App I have an internal and an external Server configured. When all persons at home, the Home Assistant Cloud is deactivated. I think the watch app uses only the external URL and not the internal URL, when I am at home.
