Also encounter the same problem. Though I know now it's about a certificate date problem. I hope this wil be resolved quickly. 

[Mainstream]

Same problem, Chromecast audios stop working altogether. Have the whole house tied into it with google hubs. This will be th reason to ditch the whole google home. No use now

[Mohamed_1976_TN]

Same issue for me and I tried to restart it using the bottom and I cannot 

[Radagast]

Mine has suffered exactly the same. Not only one Chromecast, but TWO.

The other Chromecast is working ok.

I reset my wifi, restore factory settings on Chromecast and the WiFi modem. Changed password, reinstall the Home app.

NOTHING HAS WORKED.

[jimmy22851]

Es una sorpresa desagradable, llegar a casa y querer tu Chromecast y no se pueda hacer, solo por una actualización que Google se le ocurrió. De verdad se pasan.

[geoffhailz]

Same here - my Chromecast Audio has stopped working. Done Factory reset, and all I get now is "we couldnt authenticate your device - contact support".   So its affecting THOUSANDS of people - but no official word of what is going on?

[Nass]

Is old Chromecast device is no longer working?

[durgajena]

I am facing same problem since morning. It was working fine yesterday.

[Nass]

I hope they fix this as soon as possible, 

[eduardomuniz]

Exactly the same problem here in Brazil. Yesterday it stopped working, I reseted everything and the message is that it can't authenticate.

[morf]

Google????????????????????????????????????????????????? Any communication?

[Questyn]

For those who are still looking for an answer to the chromecast device problem.

Google knows about the problem. Got to do with a certificate that ended on 9 march. 

They are looking for a fix. 

If you did a factory reset... you can fix that. Atleast, it worked for me. 

I set my android telephone date on an earlier date and installed chromecast. BUT ... it still doesn't work. So we have to wait with a lot of patience 😉

[Aire6]

Same issue with 2nd gen  Chromecast.  No problem with 3rd generation.  Software and firmware up to date.  Reset had no effect.  It worked fine yesterday.  Discovered about 8vam PDT

[Veronica2]

Alguien pudo solucionar este problema?? Mi Chromecast aún no funciona. Gracias

[Veronica2]

Alguien pudo solucionar este problema?? Mi Chromecast sigue sin funcionar.

Muchas gracias

[GermanF]

In Argentina we have the same fault, a disgrace, I hope they give a solution and do not damage the devices remotely to steal from people. A disgrace.

Desde Argentina tenemos la misma Falla, una vergüenza, espero den una solución y no dañen los dispositivos a distancia para robarle a la gente. Una vergüenza.

[Manoelvalmir3]

Meu Chrome cast 2 não está autenticando , o que está acontecendo,  não está funcionando na tv.

[Pemi]

A Catalunya passa el mateix des de ahir.
Si heu fet reset hi ha una solució per reinstal·lar Crhomecast (Encara que no funcionarà fins que Google ho repari):
Canvieu manualment la data del vostre smartphone, posar una data antiga, per exemple tres dies abans d'avui, així podreu tornar a configurar Chromecast des de Home.
Despres recordeu de posar la data automàtica en el vostre smartphone.
Salut a tothom. 

[Pete90]

Ormai sono passate più di 24 ore con soluzioni pari a zero da parte di Google😭

[Kim_t26]

Google should announce a timeline so we know whether we need to wait days or months for a fix...

[Bala2]

Mine is also same problem, help me out. 

[kgardnermsw]

Same here.  Since last night.  Very suddenly....none of the 3 casting devices seem to work anymore.

[monabri44]

There's authentication issues with my  Chromecast  device starting 9th March.

UK user.. 

[Sarahlmountford]

Same here 

[Evelyn17]

Se necesita una solucion, ya que tengo 3 dispositivos de 2da generación, y si esto pasa con sus dispositivos posiblemente el de 3era generacion y el de 4ta que tengo tambien dejen de funcionar a la larga.. Asi ya no 

[PioSte]

Guess what...

Same crap here. Everything was fine and all of the sudden my Chromecast stopped working. Thank you Google. I tried everything. Got really frustrated and ended up with nothing...

[2fr]

Même problème en France. 

Après une réinitialisation d'usine impossible de se connecter. 

Après modification de la date du téléphone au 1 mars. J'ai pu le faire remonter dans Google home. 

Mais il est toujours hors connexion. 

Et je ne peux pas non plus le renommer. 

Merci pour toutes les informations de la communauté. 

Merci à Google de résoudre le problème le plus rapidement possible. Et d'informer les ces équipes de support .

[uanidemalaga]

I got the same problem, really disappointed, i even rebooted from factory that it seem to make the situation even WORST. 😞

[berga]

stesso errore anche per me da ieri 9 marzo.

Possibile che google non dica nulla?

[Ruthjenni12]

Same here in  UK. Can't find a solution.  

[David65]

Stessa cosa sta succedendo a me da ieri sera domenica 9 marzo 2025

[PallaviB]

What's the solution?

It's so frustrating

[Jf7]

Im gonna purchase an Amazon firestick  to fix this issue

[Voletorcs]

Same issue here, Minnesota

[TigaroT]

Same issue here. And of course I followed their steps that says factory reset it and retry, but now i cannot even connect it to my Wi-Fi network. If they want us to buy new devices they should allow us to return the completely fine working devices and trade them, for a cheaper price.

[Nissalea]

True.. I need 2 devices cause you can't cast through a PS..

[Antonio656]

Lo mismo Cd Juárez México 🇲🇽 

Same issue

[JJKeeffe]

Same issue, would appreciate answer to issue when available

[Jaspreet27]

Same with me. Any update about this how to fix this?
