Same problem.  I keep checking but it is still not working.

Meu Chromecast 2 (ou 3, nao sei bem) resolveu nao linkar mais o app streaming da Amazon. Diz que ambos dispisitivos devem estar na mesma conta. Isso nunca foi exigido e nao hà como ligar em contas dentro do Chromecast. Nao tive sucesso tentando resolver.

Decidi reinstalar o aparelho dai encontra pelo bluetooth, começa a parece, exige o codigo de 4 digitos na tela da TV, mas por fim diz qye não pode autenticar: nem chego a colocar o código no app Home.

Alguém me ajude!

[jkulp]

Do you know how we get notified when this issue has been fixed?

[aldonunes]

Same here

[Dvd84]

Same problem: Chromecast not casting, tried to reboot every device, then factory hard reset and eventually not possible to reconnect the Chromecast at all for authentication issue.

[Charles12th]

Exact same thing. ????

[SpacePig]

Même problème chez moi , problème d'authentification...fonctionnait bien hier encore.

Same problem at home in France. Authentification issue , worked fine yesterday. 

[Marcos016]

Meu dispositivo também está dando erro de autenticação! Ontem a noite estava funcionando normal.

[yasmira]

Hace años estoy conectada y podía usar el Chromecast con todas las plataformas, hoy dejo de funcionar, lo reinicie, lo desenchufe, lo cambié de TV y en todas las ocasiones me dice que no puede verificar la autenticidad

Como lo resuelvo????

My need assistance with my Chromecast setup

[Anonymous]

This just happened to me ... Found this thread after trying a factory reset

[J1738]

Chromecast stopped working today and a factory reset didn't helped, its either a gen 2 or gen 3.

[ErikPidgen]

I am having this same issue.

[valentinaa133]

Same problem in Uruguay, tried to reset to factory and now it won't let me do the set up 

[Alex_197]

It' seems to ,e that this is the end of era for the Chromecast.

[nichy]

Il dispositivo Camera mia potrebbe essere configurato, ma non è stato possibile stabilire una comunicazione dal tuo iPhone. Assicurati di avere attivato l'accesso alla rete locale nelle impostazioni sulla privacy del dispositivo iPhone, quindi riprova.

continua a darmi questo errore nonostante l’accesso alla rete locale e’ attivo

[ventenlez]

Same here

[Rob242]

So according to many posts here as well as other forums online and several articles which recently showed up. It seems like it's Google issue and not your device. Apparently many people contacted Google support and they are aware of the issue and are apparently working on it to fix the problem. So to all those people trying for hours to solve it yourself don't bother because it's on their end not yours

[careban01]

Mis Chromecast no funcionan más, como le pasó a varios !!

[Misch1008]

Hi, I'm having the same issue here in Mexico, is there any update on fixing the issue? 

Model NC2-6A5

[Wilh]

Is Google going to solve the problem? It seems that this issue is affecting people globally

[ejfrank2001]

Same here. Worked this morning and last night (and always) just fine. Came home today (Sunday, March 9) and it doesn't work. Message reads: Untrusted device. "Living Room TV" couldn't be verified. This could be caused by outdated device firmware." I've got the same model Chromecast in our master bedroom, however, and that one continues to work just fine. What the heck is going on?! (I'm casting from an Android Galaxy S22, for what it's worth)

[Grace82]

Continuo errore nella configurazione (forzata da mancato funzionamento)

Mi dice impossibile autenticare il dispositivo chromecast 

Il telefono lo trova ma poi si blocca tutto

[AP83]

I’m having the same issue. Everything worked fine earlier today, but now I am getting the untrusted device error message.

[FacuMarolda]

Me too. What's going on Google? We need new Chromecast? With discount? 

[mlis]

Same… should we ditch google and move on to Roku? 

[Nanurose05]

Desde hoy al mediodia 4 Chromecast que tenía de 2 y 3ra generación dejaron de funcionar . Estoy en Argentina pero ya ví que es algo mundial espero que lo puedan solucionar . 

[PatSan]

OK. A global problem. Have a good night.

[alente]

My chromecast quit working on my tv. my phone says the firmware needs to be updated but i am unable to update it. can someone tell me what is going on

[Fab1876]

Bonjour impossible de caster sur mes deux Chromecast !

Malgré un redémarrage de box et des Chromecast.

Rien n'y fait 

[CptMorgan84]

I'm having the same issue. Was about ro launch the TV... but found these comments, seems something is going on... I did factory reset too... I'll try again tomorrow

[ferrodamarani]

Same issue here in  Argentina. 

This seems a big drawback of Google. 

[ChromecastUser5]

Me too

[Sanavio]

Same here, have 2 chromecast devices, both were fine by morning and now shows as "outdated device firmware"... come on Google fix it!!

[Edrizio]

O meu Chrome cast não quer mais conectar no meu wi-fi já fiz de tudo !

[Amartinez34]

Same issue here... 

[bfizzle25]

Just adding another voice having the same issue 

[EnPic]

Seems like programmed obsolescence to me

[alinenordon]

Por aqui aconteceu a mesma coisa. Estava normal até o meio da tarde de hoje, desliguei a TV e quando fui ligar novamente no final do dia para conectar com o YouTube, apareceu que o dispositivo não era confiável e que poderia ser firmware desatualizado

 O dispositivo Chromecast sumiu do Google Home, mas na TV aparece como se o Chromecast estivesse normal, mostrando imagens e até a hora e temperatura, como é de praxe. Fiz de tudo, tentei reiniciar o aparelho, tirei da tomada, até desinstalei e instalei o aplicativo Home, mesmo assim não consigo conectar meu celular com Chromecast e TV. 

[KRyans]

Same issue here
