Grazie,ho fatto così e finalmente il mio Chromecast è tornato a funzionare.

[Jack-in-the-Box]

You're a genius. I had factory reset my Chromecast II. Followed your instructions to "dummy" the system into thinking it was March 1, got the Chromecast running, it downloaded the security certificate update and now it's working! Google owes you $$

[Isabellekeely]

This actually just worked for me! Thank you

[Lyledw]

It actually works.

[Chansen2022]

Thank you, it helped me 😊🙏🏼 and tonight I shared your text on Facebook groups for Denmark, I think it can help many who have had to reset their caster.
Good Evening to you!

No sé puede autenticar Chromecast. Estoy al tanto que ya muchos pudieron hacerlo. En cambio yo reinicié mi Chromecast de fábrica. Después, ya TARDE Google aconsejó no reiniciar.

Entonces pregunto los que lo hicimos no vamos a poder autenticar hasta cuando? Y que debemos hacer.

Si nuestro Chromecast no sirve más, que nos digan qué tenemos que hacer.

Muchos veo que mencionan a FIRE TV de Amazon, pues no lo sé con certeza.

Hay otro cómo ROKU TV .

TIENEN QUE DECIR ALGO Y CUÁL GENERACIÓN ES LA QUE IRÍA.

ESPERO RESPUESTA. DESDE YA MUCHAS GRACIAS.

Changing the date on my tablet to before the problem and re-installing my Chromecast Audio ( I performed a factory reset), fixed the problem. After fixing change the date back. Happy listening!

[Laribrasil]

Please fix the chromecast as soon as possible, all my chromecast devices are not working yet.

[johnnyzero2]

Read the status updates pinned at the top of this page. Google started rolling out a firmware update fix yesterday.

If you've done a factory reset on any of your Chromecasts, you need to do this fix to allow them to receive the update:

As part of the recommended troubleshooting I am guessing I am not alone when I ‘reset’ the device - so now what? Will this be fixed? And when? This is very frustrating.

My son gave me his chromecast as he didn't need it anymore so he is getting the updates regarding the authentication issues and I'm not. How can I get the updates as my chromecast isn't working. 

[johnnyzero2]

Did you perform a factory reset on yours? If so, then you'll need to do this procedure to allow it to receive the update:

[GabrielXigliano]

I performed a factory reset, but, i take my phone and change the date to 6 of march of 2025 and enter the app google home. I tried to configure the chromecast and I got it, becouse the app use my local date for configuration.  You can make a specific application to give a fictitious date to the chromecast when configuring it.

[sbharvey374]

I am sorry this response is in English, leave your unit on with your Wi-fi on, the google server will download the appropriate certificate, so your casting will work for all of your commercial apps.
