Problem Cert SSL Android Companion App

[mpatrix]

From some weeks i reciveing an error from android app companion to my Home assistant installation on 2 different place.
Behind the server I use CloudFlare and work correctly if I access by Chrome but I receive cert error from the app.
On other devices with android or ios work correctly on app and web. I've try to clear cache, remove date, uninstall, reboot, reinstall.... same problem.

The datetime of the phone is correct and I use a Galaxy S22+

Can you try to help me?

Thanks in Advance!

Please see #5891

The short version is: a certificate that may be used by Cloudflare's chain is no longer trusted on Android. This is not a Home Assistant-specific issue.
