Chromecast (2nd gen) and Audio cannot Cast in 'Untrusted' outage [U]

9to5google.com Chromecast (2nd gen) and Audio cannot Cast in 'Untrusted' outage [U]

Over the past few hours, owners of the Chromecast (2nd gen) and Chromecast Audio haven’t been able to Cast any audio or video content.

I was wondering why my Chromecast was suddenly untrusted. An update seems to have knocked off older Chromecast devices globally. People are factory-resetting them before they know what to do, making the potential fixes even harder.

Some apps still working is because the authentication is not mandatory.
Screenshot from Tweakers.net discussion:

Factory reset isn't the end of the world, I did it to my gen2 Chromecast when the outage first happened and managed to get it connected again by rolling my phone's date back and finishing the setup.
This article was super helpful and helped temporarily restore casting functionality from my phone. https://mensfeld.pl/2025/03/bringing-your-chromecast-back/

Is there any alternative to chromecast out there with more privacy?
- Yea I mean dlna/upnp is open, Chromecast solves the problem of a cheap, small bit of hardware to do that. It's a bit of a mixed blessing. They sell at what must be a loss*, maintain backwards compatibility at I'm sure a huge expense, all to get your data.
- DNLA/UPnP
  
  Apologies, I'm no longer as technically literate as I used to be. I've no idea what that means.
- Bluetooth

It's a bug. They're aware and working on it

We have a Chromecast 2nd generation which has indeed the known problem. However when I use Music Assistant from Home Assistant I can cast from my own music collection (flac files).
I haven’t tried yet to cast from Spotify using Music Assistant.
I own an iPhone and casting a Youtube video indeed doesn’t work. This results in receiving an untrusted device message.
Questions now coming up are
why are some apps still able to cast to a 2nd generation Chromecast?
are there more apps still working?
