What do I do now since both my devices were factory reset yesterday?

Is it junk?

[PallaviB]

Cant authenticate your chromecast.

Suffering from 48hrs!!

Solveeee it Asap

[drossiter]

Why did your tech support explicitly instruct me to factory reset my Chromecast 12hrs ago when I reached out with this issue. Unacceptable - expect better from Google.

[YVAnichyy]

Onn. Brand from Walmart sells a casting device powered by Google Tv for $15. So far so good! Cheap alternative until Google figured out wth they’re doing!

[Jobs05]

Me ajudem!!

Pediu pra atualizar aí eu fui e redefinir, e agora não quer autenticar...

@Jobson05

[Juliana1]

O meu também não autenticada mais 

[Gabiconminusxul]

Os meus dos Chromecast 2 tambem 

[Paulo26373]

Parece que é um problema mundial, gente de todo canto reclamando. Principalmente o modelo segunda geração. Aguardemos o Google resolver isso.

[fjbenitog]

Since yesterday my chromecast v2 stop working.

I reseted and now I am not able to link any more. Due to authentication issue.

I saw on the Internet that it is happening to more people.

Do you know when this will be fixed? 

Thanks

[Wilma2]

Same Here, have tried reset the home app, My phone, My router, My chromecast but nothing worked, this all since yesterday…..

[EC3]

Google is working on it (they say). See Reddit for more info: https://www.reddit.com/r/Chromecast/comments/1j7lhrs/comment/mgzcw4e/

[Samaritan71]

Same. Factory reset 2x but still can't link. 

[martassanchez42]

Me pasa lo mismo desde ayer . Me dice que necesita auténticar y ahí se queda pillado 

[alinedelorenco]

Have the same issue, thought it could me my device but apparently it's a bunch of people facing this

Has google said something about it?

[alvarenga7udb]

If you did factory reset, please see this article, it served me well, as I also did a factory reset. This only works to get the google chromecast show the google stock wallpapers, but we still have to wait for the issue to be solved.

After troubleshooting and trying all suggestions including do a factory reset, now I see it's a known issue and not to do a factory reset 🤦🏼‍♀️

[BadFlash]

Yeah but you can add back the ChromeCast to google home if you change your phone date’s to March 7th 2025 and add the CC back 

[edugaedke]

Oh, finally found some official communication about this issue! 😀

Sadly I've already factory reset my device. 😨
Please tell me it's not bricked!

[BadFlash]

It’s not bricked .  Just set the date of your phone to March 7 2025 , add it back in google home and reach the point where an unexpected issue has occurred … like mentioned in many threads here and on Reddit .

[Pendicle]

Oh, brilliant advice about not resetting! Its pretty much the first thing anyone will try when their casting doesn't work. Some of us will try it a few times in between resetting wifi hubs etc.

[Inpatientpsych]

7pm March 10th... still not fixed 😞 

[NeoDC]

Most people have done a factory reset, now what? I reset my WiFi router, my phone, and my ChromeCast. We need this resolved asap. This is 2025. And it’s Google. Fix it fast please thanks 

[Ryanhi]

Please provide a fix status update and ETA.

[AP24]

Chromecast dejó de funcionar. No se puede "autenticar" mi Chromecast. Van a solucionarlo? Tengo que comprar otro? Alguien tiene alguna solución? Gracias. 

[Sharky77]

Already booted reset as per website instructions that you may wish to amend.

[Lauradunne]

Hi my chromecast keeps saying we couldn't authenticate your device I have tried absolutely everything that's recommended and nothing can someone help me I'm not sure what gen I have either

[AnnLuccy]

Ontem 09/03 Chromecast parou de funcionar também 

[Frama1303]

Yo tengo generación 3 y desde el 8/3 no funciona tampoco

[eduardotigerrey]

No funciona el de nadie, hay que dejau de usar productos Google por la falta de concideracion a los usuarios. Te obligan a comprar el Google Streamer que cuesta 119 euros o una Smart TV con Google TV que cuesta muchisimo mas!!! Eso es una falta de respeto a los consumidores!!!

[newnikka0412]

Tried all the suggestions but it's still displaying "we cannot authenticate chromecast ". What to do??*

[BadFlash]

Wait for google to fix it... from what I've seen, last time it took a month or so to come up with a fix.

[Claudietta]

Anche io da ieri sera non riesco più a configurare il mio Chromecast....vedo che il problema è comune a tutti.

Pensate che si risolverà? Da cosa dipende? È la prima volta ,dopo tanto tempo che ce l' ho,che mi capita

[ChromecastProbl]

I also experienced this issue, all devices working perfectly fine yesterday. Now none of my chromecast devices work!

[danisode]

They want us to buy apple tv instead 😉

[ElevatorBread]

Lol maybe they are tired of everything
