POSSIBLE TEMPORARY FIX:

It appears that someone at Google overlooked updating the essential certificate files for the Chromecast (2nd Gen) and Chromecast Audio, which is possibly causing the problem. One Redditor claims that the intermediate certificate authority for the Chromecasts (2nd gen) expired on March 9, 2025. Due to this, Google's servers are not validating these devices.

I changed the date on my phone as was able to get it to work!! 

[xiexiexiexie]

the same issue, I reboot the chromecast, but couldn't authenticate it about on March 8,2025

[Pandee]

Try changing the date on your phone to before March 8th and it should let you do it!

[xiexiexiexie]

Maybe on March9,. When I manually set my phone’s date before March 9, 2025, I can use the Google Home app to set up Chromecast, but still can not cast anything.

[Freakshow1]

Just here to say I'm also experiencing this.  I was going to reset it until seeing others had tried that, already.  This coincided with me linking to Nest and I thought that was the issue but it seems to be a coincidence. 

[Rachaelmariexx]

Last night our chromecast wouldn't connect. Tried again tonight and still having the issue. Decided to reset it and add the device again. Getting the "can't authenticate" messenge.. looks like we aren't the only ones! 

[Hevi]

Dicen que es solo para chromecasts de 2da generación..  es cierto? Sería bueno coloquen cual generación o modelo tienen?

[hkarbatia]

Same, issue, couldn't authenticate your device message, or untrusted device, mine is old. Any clew to fix it please.

[Sanjayjha]

Same here

When can we expect resolution??? 

[Bruuu]

Boa Noite,  o meu chromecast parou de funcionar,  não autentica... logo no início,  

Já fiz todos os procedimentos possíveis, não adianta. 

O que será que ouve? 

Tem alguma solução?

[jpgandrade90]

tô nessa tbm, mesma coisa aqui

[Bruuu]

Muitas pessoas estão reclamando da mesma situação,  deve ter sido uma falha do Google, já tentei de tudo,  tenho 2 chromecast,  1 está normal,  mas o outro parou de funcionar, não sei o que fazer.

Você teria alguma solução?

[Geysabranco23]

O meu também já fiz de tudo e não funciona. Pelo visto não é só eu que estou com esse problema triste

[Bruuu]

Tomara que seja um erro e volte ao normal,  a minha TV não é smart e precisa do chromecast para conectar a alguns canais que assiste online. 

[mouragracia]

A minha TV também. Sem o chromecast ela perdeu a função. Que absurdo o google não resolver isso.

[Bruuu]

Eu tô achando que desativaram os chromecast 2 , muito tempo sem resolver 

[Polyanne]

O meu parou hoje 09/03/2025, reiniciei e na configuração aparece o erro, "não foi possível autenticar o Chromecast. Acesse o suporte...

[Bruuu]

perdemos o chromecast??

[Darth1]

O meu também parou no dia 9 de março.  Diz que não é possível autenticar. Reset não funciona 

[mouragracia]

O meu também parou dia 09/03/25

[mouragracia]

Está todo mundo na mesma situação. E o google nada de resolver.

[Bruuu]

E acredito que tiraram as atualizações do chromecast 2

[Bruuu]

E o suporte não resolve o problema 

[Geysabranco23]

Será que é uma falha no Google gente não é possível todos os cromecast pararem de funcionar. E logo no meu dia de folga acontece isso. 

[Bruuu]

Eu acredito que é uma falha do Google 

[Will39]

O meu tbm está assim 

[Gonzalonog]

Si yo creo lo mismo, no es normal que dejen de funcionar de un día para el otro. Mañana se verá qué pasará 

[Ferrao]

Aqui a mesma coisa. Já resetei 3x. O Google home não reconhece o cast

[Milk1]

Mesmo seguindo todos os protocolos não foi possível autenticar o chromecast. Alguem tem alguma informação oficial do que pode estar causando esse problema?

[Bruuu]

Também gostaria de saber,  estou achando que o crhomocash 2 saiu de linha 

[mouragracia]

Chromecast para de 

Google diz que os usuários não devem restaurar as configurações de fábrica. Solução está em desenvolvimento.

Eu resetei umas 05 vezes. Mas li em algum lugar, que mesmo quem restou o google vai dar o passo a passo. Quando? Só Deus sabe.

[Bruuu]

Mais , o problema é que as vezes é preciso reiniciar para resolver problemas.  Complicado.

Thanks in advance !

[Tane]

So when is this update coming?

[mkgarcia]

How to resolve this?

[Aldi80s]

As far as I see... we have to wait till the fix comes.  Who knows how long would it take !

[fortniteglazer]

[Uninstall]

Bruuuuhh, what's your issue about bruh?

[Aldi80s]

Hehe... personally I never liked Apple... the programmed obsolescence is wilder than Google's.
