Do you have an updte on your time frame? By now my streaming apps aren’t even seeeing the google chrome cast audio anymore nd google home still says it is off line.

[Pipisback1]

For those who reset their device to factory settings, simply disable automatic time and date settings on your phone. Change the date a few days before March 9th, then start the reconfigure from the google Home app...that's all..!!

Quando irá resolver o problema não consigo acessar pra por a internet aparece q não foi possível autenticar o Chromecast 

[Mic72]

Io purtroppo ho effettuato il ripristino ieri 14 marzo e ad oggi non sono ancora riuscito a collegare chromecast. Cosa si può fare ? Grazie e saluti

Hi everyone, Just wanted to share my experience. I performed a factory reset on my device, which Google had advised against. After the reset, I rolled back the date on my phone, and the connection was successful. Following this, there was a firmware update from Google. Now, everything works fine—I’m able to cast all OTT platforms and YouTube without any issues.

Hope this helps!

[csabb3510]

During setup Google Home cannot authenticate my Chromecast device. Is it the current problem experienced by others? Thanks in advance!

[Dutchgirl]

Set your Phone date back to March 5.

Bonjour, 

Suite aux différents commentaires sur j'ai lu, j'ai pu réparer ma Chromecast.

Si vous avez remis l'appareil à l'état usine comme moi, Voici la procédure à suivre :

1) changer la date de votre smartphone au 8 mars 2025 via "paramètre/paramètre supplémentaire/date et heure"

2) ouvrez google Home et ajouter un appareil Chromecast (la configuration de l'appareil, la connexion au wifi et les remises à jour vont pouvoir se faire) 

3) à la fin de la configuration j'ai eu un message me disant que ce n'est pas encore possible de terminer la mise à jour entièrement pour l'instant, appuyez sur le bouton "quitter la configuration" et fermez google home.

4) remetez la date du jour sur votre smartphone 

5) redémarrer google home : la Chromecast est à nouveau fonctionnel !

tried this multiple x's....NOT WORKING!!!!

Hi,

I had to change my router and wireless SSID as part of a wireless infra upgrade. So my Google Nest Mini became unresponsive due to the network change. So I had to perform a factory reset as part of connecting to the new SSID/wireless network and now its still unresponsive after setting up in Google Home app.

Is this because of the issue noted in this thread? If so, when can we expect a workaround for folks in my situation?

[Paquivel]

Por favor, avísenos cuando esté solucionado para restablecer los valores de fábrica. Gracias.

[Pandagopanda]

Qui factory reset. 

Ho cambiato la data del mio smartphone al 15 febbraio e poi provato a riconfigurare il Chromecast. Ebbene, ci sono riuscita! Dopodiché il Chromecast si è aggiornato e ho potuto usarlo con la data corretta.

[SteveH855]

My chromecast audio started working again today.

THANKS for fixing this. 

[Fredica]

Work for me too. Changed the date to 28th of February and update after that.

[Anonymous]

I had already done the factory reset here's how I fixed my chromcast,

(Andriod) settings - general - date time- turn off auto date/time setting, manually set date to MARCH 8,2025 then I was able to connect it to my WiFi, let it sit over night, next morning there it was ready to use, works perfectly again, you can turn your auto date setting on again as soon as your chromecast is connected to your wifi

[Mohamad227]

[Dutchgirl]

I did what someone said here earlier: set the date of my Phone back to March 5. I had reset my chromecast to factoren settings. Now Google could not find the chromecast and so i could not make an setups again. 

But with the date on March 5, in no time the chromecast was found. Had only to rename it. Im not sure about the update...but so far i can stream again 😃👍
