In English:
1) Change your phone's date (before 9/3/25) 

2) Complete the installation from the Home app 

3) Install Activity Manager, go to the Launcher option, then to "Action," paste the following: com.google.android.gms.cast.settings.CastSettingsCollapsingDebugAction, then click the "check" button 

4) Enable the Bypass Certificate option 

5) You're now ready to use your Chromecast

2) desde la app Home finaliza la instalación 

3) instala Activity manager, ve a la opción laucher, luego a "action" pega lo siguiente: com.google.android.gms.cast.settings.CastSettingsCollapsingDebugAction, luego dale a la "palomita"

4) activa la opción omitir certificado 

5) ya podés usar tu Chromecast

[fasosl]

Waiting for the fix

[Molina2025]

When Chromecast is working properly our Chromecast is not working 

[JOS7]

Bro, just CTRL + Z

This is unacceptable. 

[dgwalizer]

As a work-around, I've found that configuring the chromecast  device as an Open Home (DLNA) renderer with bubbleupnp allows you to cast to the device as a DLNA renderer.

[Cymer]

How long will it take? 4 days it's already a lot!!!

[Concerned]

I factory reset before seeing this. Am I hosed now? I really love this device.

[HauntedinNY]

I went out and bought a Wi-Fi capable TV and now I don't need Chromecast anymore. I'm done waiting. Five days is too long to wait. 

[Chantala]

When is the service going to be back up?

[Rafaella]

Não consigo conectar ele com meu celular, qual ser o problema?

[Maru79]

Muchas gracias! Espero que se solucione rápido el problema y me informen así puedo volver a usar el dispositivo. Nuevamente, muchas gracias! 

[Mariangel]

Hola, estoy teniendo problemas con mi cromcast.  Lo e restaurado de fabrica porque hace varios dias vengo sin poder usarlo y arroja un msj qué no se logra la autentificacion. Como puedo solucionar?

[DanielleLucena]

Infelizmente resetei o equipamento, por favor o que fazer agora,  pq tento seguir os passos a não resolve mais!

[vanesaschwemmle]

• También restablecí mi dispositivo a la configuración de fábrica, pero encontré la manera de dejarlo como estaba, pero sigue sin conectarse al televisor. Lo que hice fue ir a Ajustes, General, Hora y Fecha en mi iPhone y cambiar la fecha al 7 de marzo de 2025, antes de que caducara el certificado. Configuré Chromecast como siempre y todo volvió a la configuración original. Sigue sin conectarse al televisor, pero al menos está listo para cuando se implemente la solución. 

[DanielleLucena]

Vanessa, vou tentar. Vamos aos passos, 1 mudo a data do telefone?abro o app home e  configuro o equipamento sem conecta-lo a TV? 

[Jorgemorenor]

Send me the information, because did the factory reset.

[Maddiegirl64]

C'mon Google. My devices have been down since Monday afternoon. It's now Wednesday night. How bad was the hack? And what personal  information was stolen?

[NZsportbiker]

Nothing to do with a hack?

[MarceloM1979]

Although I was able to bring back my devices by using an android tablet with the date tweaked to  March the 1st, all of the devices are offline... aaaaaand then also I'm noticing that my chrome is not picking up the broadcast icon while on youtube when I have a LG 65" TV that has the ability to pick up broadcasts... maybe related, maybe not... any idea on E.T. for the fix? 

[Martinbarriga83]

Last Monday I brought a Roku device on Amazon, it will come from Amazon USA to Mexico tomorrow, I think that 4 days is enough to wait. I lost the hope to use again Chromecast, I guest that google wants to sell new products but if they can not fix this right now we should not buy another google tv device.

[MeliSalatin]

Sorry, Ive already reset my device. So I'll wait for the instructions as soon as possible. Thank you

[Emerson_emmalve]

Se não é para restaurar, porque ainda mantém essa instrução na página de ajuda deste dispositivo. Há uma contradição aí sobre essas orientações.

[Arqbrown1954]

Lamentablemente micjos usuarios no tuvimos aviso y reseteamos el dispositivo

Que podemos hacer?

[Luxess]

combien de temps pour régler le problème devons nous allez acheter un autre cast avec autre compagnie.

[Msmonnbebe]

Great, already factory reset on day one. 

About to just throw it out,
