Ours stopped working yesterday out of the blue (we couldn't stream to it). I thought it was broken. Tried a factory reset, and following all instructions on Google Home, all to no avail.<p>Checked out Reddit and it turns out lots of folks are experiencing the exact same issue across the world. It all started a couple days ago.<p>Anyone have any idea what's up?
It's an expired intermediate certificate in the chain of the device certificate.<p><a href="https://old.reddit.com/r/Chromecast/comments/1j7lhrs/the_chromecast_2s_device_authentication/" rel="nofollow">https://old.reddit.com/r/Chromecast/comments/1j7lhrs/the_chr...</a><p>and<p><a href="https://www.theregister.com/2025/03/10/google_chromecast_outage/" rel="nofollow">https://www.theregister.com/2025/03/10/google_chromecast_out...</a>

I managed to temporarily fix my casting from android phone to TV today by fdroid activity manager to ignore certificates for casting using some instructions I found online. It's working well now.
Tldr: certificate expiration. See [0] for details and fixes.<p>[0] <a href="https://mensfeld.pl/2025/03/bringing-your-chromecast-back/" rel="nofollow">https://mensfeld.pl/2025/03/bringing-your-chromecast-back/</a>
