Outdated device firmware issue in chromcast 2. Reset done , device trying to setup by google home. But not connecting (setup break down)

What the hell is going on with authentication thry kno exactly whats going on it is very widespread when are yall going to fix this we not stupid its something  yall habe done evil ass people 

[janellemclaugh]

It sounds like you're frustrated with an authentication issue, and I understand how annoying that can be. If you're facing problems logging into a service or dealing with unexpected authentication errors, it could be due to a system-wide issue, security updates, or account verification changes. Try resetting your password, clearing cache, or using a different device. If it's a widespread issue, the best option is to check the service’s official support channels for updates. Let me know what specific problem you're facing, and I’ll do my best to help!

Hoje eu e diversos usuários do Chromecast nos deparamos com a não conexão via Chromecast!!! Já tentamos todo tipo de ajustes, mas não é passível concluir a conexão com o aparelho Chromecast aparecendo uma mensagem de que o aplicativo não é confiável! Por favor arrumem isso!!!!

[RonaldoSch2]

Ao resetar o chromecast por que estava dando erro de conexão,  após o programa confirmar e perguntar se vc quer configurar o chromecast2296, logo após a confirmação de configuração recebo a mensagem "NAO FOI POSSIVEL AUTENTICAR CHROMECAST ". isso está acontecendo nos meus 2 chromecast. Como deve fazer pra resolver esse problema.  Obrigado 

[Chakan24]

Parece que todos os dispositivos Chromecast de segunda geração pararam de funcionar hoje devido a um prazo de autenticação que eles tinham como limite. Não sei se o Google fará algo a respeito, mas há muitos usuários ao redor do mundo reclamando da mesma coisa, inclusive eu.
Um usuário do Reddit encontrou o problema, aqui está a postagem.

[patriciab]

simplesmente parou o chromecast... sem aviso prévio,  notificação ou algo parecido... parou e milhões de brasileiros ficaram sem TV neste domingão 

[Rajin2025]

Hi, Chromecast is not connecting with my android devices

[Gigi2]

I have the same problem how can i fix it 

[ALinNYC]

Cast down since 3/09

[Perloncho]

I got the same issue with both my iPad and my android phone, and I followed all the steps to solve it but nothing 

[konsens]

I currently use 4 Chromecast Audio in various rooms. It worked until it recently broke. It seems clear that it will break forever one day. What can I use as replacement? Will Google send me (free? lol) replacement Google TV thingies and will they work nicely without screen attached? Is there some other vendor I should take a look at?

If Google dropped doing audio-streaming, I loose the main reason to use Google Home at all. If switching to Home Assistant or another platform, which is the easiest way to do audio streaming? I use Youtube premium for convenience with Chromecast for now, but I could easily switch to something else if I have to switch devices anyway. Suggestions on streaming provider+hardware provider combinations to look at after dropping Chromecast audio?

[Beelzabeth]

I'm a little frustrated. I just found this thread. I reset it as well... 🥺 now how am I supposed to watch creep cast on my TV?

[flavia1]

O chromecast deixou de funcionar de repente. Estou há muito tempo  a tentar tudo por tudo para voltar a ter o serviço e nada. Já testei N coisas, desliguei e liguei 700 vezes, já fiz tudo o que aparecia de sugestão na internet para fazer e simplesmente não dá. O suporte técnico ao domingo está encerrado e no entretanto estou há imenso tempo  sem televisão. 

[flagdar]

Ao parecer o problema e geral, mesmo problema por aqui.

[Romi2]

My Chromecast suddenly decided to not work/ connect to my TV today. 

Can't seem to even add the device on my Google Home. 

It's like disappeared from my network 

[Mithunkumar]

Chrome cast stopped working from the morning 

[MAJ]

I thought that I had done something to cause this issue! Relieved to know it wasn't that. Unfortunately, I found this article AFTER I had already performed a factory reset. Looking forward to resolution. I'll also let Spotify support know it is not an issue with their app!

[waqasqadri]

Hi, Is this issue fixed?

[tigur11]

not yet sir, contact and call google nest support here: https://support.google.com/chromecast/answer/10109908?hl=en

13 hours later. Where are the updates guys? 

[GXORGXX]

The fact this hasn't been dealt with yet really does show the lack of loyalty Google has for it's long standing customers. Just because we have adopted the products early and you kept making newer versions doesn't mean we should suddenly be robbed of all access and use of something we paid for regardless of length of time. You are going to lose a lot of loyal customers due to this and the lack of attention that's been shown in assuring customers you are aware and and "trying" to resolve it. I've had to hunt for this information myself and found it in forums. Not Googles official X account or Facebook. Not even their own website. It's not fair at all and truly i feel robbed. I have invested so much money making my home smart woth Google products and i finally think my time may have come to jump ship because this isn't on at all. 

[mosswilliams12]

Lost chromecast connection a few days ago. Tried "everything" according to troubleshooting guidelines.

Get message "Something went wrong" between iPad and Chromecast.

Please send message with fix, or publish online via a National NEWS site (Sydney/Australia) !

[Raf0]

Molti utenti hanno già ripristinato, poiché consigliato nelle soluzioni dei problemi.  Avete dato comunicazione troppo tardi. Chi come me ha ripristinato il dispositivo,  cisa deve fare ora? 

[Heartinfocus]

I have already disconnected from power and tried a reinstall, because that’s what your help guides said to do.  Please fix this and tell us how to set up our Chromecast devices again! 

[Mìléja]

Thank you, how will you contact us when its resolved? I've unfortunately already factory reset my device

[mickeymikevegas]

Yes I'll need instructions for what to do after a factory reset. My Google Home App is now saying it can't authenticate my Chromecast device. Even before factory reset, I unplugged the  Chromecast device, the router for over a minute, and nothing changed. 

[Puurtaja]

Turn back date on your phone to 8th of march and you can add chromecast back to your home. Still cannot cast or anything but then you can sit tight and wait for fix 

[Valeriedls]

Of course we're gonna do a factory reset, it's one of the options when you click on Get Help 🤦🏽‍♀️ Hope you release the fix ASAP. 😓

[Mathra54]

Any update 

[emilio11]

credo che e solo una scusa perche la prima cosa che si fa e ripristinare le impostazioni di fabbrica

[WuSi]

It is almost the standard procedure to reset the device especially the Google help for problem solving also suggest trying to reset your device.

[emilio11]

e quello che dico anch io

[Babbatool]

Day two of not being able to listen to music at home 😢
