will someone sent me email when this is fixed

[philipjhudson]

as of 10 pm eastern time on 3/10/25 my Chromecast is not working

[Balajiivish]

I just factory reset my device since it showed error showing that my Chromecast is using outdated firmware. How to fix this and get it online. Please help

[tomasb]

Exactly! did they change FAQ page already to not do that? like a thick red banner on top saying that 2nd gen devices experiencing an issue, and thus owners should not follow FAQ, and NOT reset their devices?

[Jô]

Eu restaurei o meu que apresentou problema desde sábado.  O que devo fazer?  Aparece todas instruções de instalação e não pega.  

[Kat20]

Any updates on the fix? I'm in NZ and it's driving me nuts that I can't cast my streaming services. 

[CarolRmz]

El problema con mi Chromexaste esta hace más de 24 hrs.... hubiera sido bueno saberlo antes de haberlo reiniciado a valores de fábrica. 

[tomasb]

Maybe the next time, acknowledge the issue and issue the warning a bit earlier than that?

Already reset. BTW, your users are conditioned by now to hit reset. I don't think I need to elaborate why is that.

[Kazdig]

What is the eta on a resolution? This is a major inconvenience with little communication coming out. 

[tomasb]

Not reset the device, eh? When your FAQ are riddled with suggestions to do exactly that! Get real, google. Or did you get rid of any thinking person?

[msing002]

What if I've already factory reset my devices?  I've been constantly trying to connect both Chromecast 2nd gen that I have and they continue to fail.

[clairann26]

Please email me when fixed # 

[tomasb]

Where is communication on how you are going to reach out to those who already did do factory reset as per your FAQ instructions?

[sprtplt]

Well???

[MannyLabbe]

Well it's weird, you knew it was going to happen.. right? If you didn't, it's even worse...! Big Google for a long time, but not so much right now 

I have 2 unusable devices.. and I would have appreciate to know before it happens, bad customer experience.

[johnbutcheracad]

I did factory reset my device. Pls, provide instructions to set my device back up.

[lagunalax]

Keep me updated when this is fixed. I already factory restarted my device

[Snh6227]

Wow glad I find this post after I factory reset my device. Working in t3ch that's always one of the first few things to try. Power cycle it, if that doesn't work try factory reset....

[Tb26]

How much longer until it’s fixed? Are we talking hours, days or weeks? 

[Madcow]

REF: Chromecast 3rd gen; unable to authenticate re-setup of device. Authentication of the 4-5 alphanumeric characters (input/ popup) does not come up in the setup process. Authentication error is then displayed on Android (Pixel mobile phone) screen.

How will we be notified of the instructions to reconnect our devices if we have already reset them multiple times? 

Will this be distributed as an update with those necessary instructions? 

[PeanuttyRandy]

Chromecast was acting up, ended up removing the device from my Google Home favorites.  

Tried to reinstall it,  but having issues. After looking to see if others had something similar,  it looks like I wasn't alone with this recent technical issue. 

Is there a contact / email list I can add myself on to be notified when the issue has been fixed so I can reinstall my chromecast? 

[Djjuniormix3]

Any update on this, I factory reset mine and now I can not get it back .

[dadiazve]

Y ahora cuando darán la respuesta de que se debe hacer para los que reiniciamos los dispositivos?

[Rka027]

Already done the reset and stuck like anything, I mean this is really unethical, There should be heavy tariff from every country on every product by google

[JJKeeffe]

Thanks for working on this. Would appreciate to know when solution is in place

[Barbara84]

No se pudo verificar Chromecast. Esto podría deberse a que el firmware del dispositivo no está actualizado.No se puede reiniciar porque sinlo haces te dice que hay que autenticar es como si al dispositivo lo hubieran dado de baja. NO HAY MANERA DE SOLUCIONAR ESTO por mas intentos que uno haga. Quiero soluciones de parte de google ya sea que lo arreglen o de lo contrario informen que no va más estos dispositivos. PD. soy de argentina

[jmorfing]

Tengo el mismo problema desde hoy. Espero lo solucionen para mañana. Domingo de bajón sin tele

[Ort]

Estoy igual desde hoy 

[lolo10]

Mismo problema desde España , en Extremadura 

[subyuga]

Me pasa lo mismo desde hoy. En mí compañía de internet me dicen que es un problema de Google. Venía funcionando bien y de repente cayeron todos los Chromecast de la casa. Habrá solución?

[Reneldnov]

Desde hoy 09 de marzo del 2025, el mismo problema, mis 2 chromecast quedaron sin uso... alguien ya tiene la respuesta??

[Barbara84]

No. La verdad que vi post desde hace 7 hs en algunos lugares del mundo que esta este problema.  Un bajon.. 

[lolide]

Yo estoy exactamente igual...no entiendo nada, he probado de todo... alguien sabe solucionarlo?

[Barbara84]

Hay que esperar a ver que dice Don Google. 

[Ort]

No he probado de todo hasta conectándolo a otro tv reinicie todo desinstalé app Home y volví a instalar y nada funciona 

[Barbara84]

Por lo que leo hace tiempo.. en ingles sobre todo es un problema mundial que proviene de google.. y todos estamos en la misma. Probaron de todo y no funciona. Todos piensan que dejaron de dar soporte de un momento a otro a los dispositivos viejos para que la gente compre los ultimos. Lo cual estaria mal xq minimamente deberian avisar. De todas maneras yo pedi ayuda y quedo mi reclamo en curso...calculo que todos deben decir lo mismo

[Videl105]

buenas soy de Argentina también y tengo el exactamente el mismo problema y me aparece el mismo mensaje. Evidentemente es general porque en Brasil también esta sucediendo.

[Barbara84]

Es en todas partes del mundo, lei desde inglaterra, holanda, etc.. alla sucede desde mas temprano. Y ellos directamente llamaron a google x lo que lei y dicen que hacen lo mismo que me hicieron a lo abren un caso y lo dejan en curso

[Ort]

Habrá q esperar a q lo solucionen es un bajón porq estos dispositivos son de uso constante también soy de argentina Córdoba. 

[Vic01202]

Vivo en Usa y tampoco funciona me sale un error de autenticidad algo asi. Hoy en la mañana funciono bien.
