Ayer me pasó lo mismo.

Sabemos cuanto tiempo puede pasar?

Como sabremos que ya se ha solucionado o lo que tenemos que hacer para que podamos seguir utilizando el chromecast?

[matthieubrucher]

A bit too late as THIS IS THE ADVICE YOU TOLD PEOPLE!!!! I already did factory reset.

[FAOD]

How do you plan to notify us when an expected fix is coming? And for us that have factory reseted, how will you provide us the instructions you mentioned? 

[Kirtipur2]

Please be quick! It's been a day already!

[Marymartins]

Mude a data parando dia 08 e refaça a configuração 

[Sirenanegra]

Estoy casi al borde del colapso, tengo tres Chromecast y nada funciona

[Marymartins]

Mude a data para o dia 08 e refaça a configuração 

[Perspectalog]

Ah just factory reset it obviously 😅 like two times... 

[Vishnu1981]

Same problem for me aswell. I did factory reset.please send instructions.

[Mrbaseball77]

imposta una data antecedente al 8 marzo sul cellulare dove hai installato google home e riassocia la chromecast. vedrai che funziona l'associazione. per il ripristino dello streaming dobbiamo antedere google.

[Pierre38320]

Comme beaucoup j’ai suivi la procédure et j’ai réinitialisé mes 2 chromecast. J’espère vous allez apporter une réponse à tous les utilisateurs de cet appareil. Merci

[Jindabyne]

How will Google send the instructions if we all did a Factory Reset?  Is it sent by email to all Google subscribers?

[colo5k]

It's great to read "don't factory reset" after doing the factory reset...

[Hallando]

Change date on your phone to 7 of March, then you can set up you chromecast and wait for an update, worked for me🙂

[Seriouslytho]

Well that's brilliant. Troubleshooting 101: factory reset. Did that before searching the authentication error...

[Hiddledip]

Any update on this? @GoogleNestTeam 

Even a simple "still working on it, no further updates" would be highly appreciated. 

I'd like to be kept in the loop with a regular update, even if nothing has happened yet - feels like you care ✨️

[Caduser]

I have said this before, but despite your decision to fix this issue, it's really important for Google to understand the scope of influence the group of people have who use devices like CCA. This group, most of whom are active Redditors, are the people helping people with technology and their decisions to invest in it. Don't underestimate us. CCA is one of my personal favorite devices ever made, and has been a major reason to further invest into Google's ecosystem. I will not stay without it.

[LexiC]

Ya to late .. already factory reset mine... I mean that's how most of us fix connection issues with the Chromecast so that was our first thought was to factory reset... so many people have done this. Hopefully we can fix this. 

[IRONcladUK]

Same... First thing I did then after a day of no success saw the first post re the issues...

Quite disappointed with this whole situation...

[gerent]

I hope this is not planned obsolescence, because I happen to like my casting device.

[Daniellexx]

Hopefully a reply here as soon as its fixed so people know when it's able to be used again. Most of us paying for subscriptions on apps we cannot use. So frustrating.

[Mercedes13]

WHOEVER FIRST MENTIONED SETTING YOUR DATE BACK BEFORE THE 8TH IS A GENIUS!!!

[sshriwas]

Is there a expected time to get a fix?

[moisie]

Normally when something doesn't work, you have to try several things and eventually you can try a factory reset. And then this time, the advice is to NOT do the factory reset... POOF too late... Hope the solution to that one will be easy and sufficient.

[Whiteorourke]

Same issue here in Ireland, hopefully this will be fixed very soon 

[Ali1138]

Hi, I have thus chrome home for 5 years but yesterday suddenly found the chromecasting not working I tried to switch off and on that it's says we couldn't authenticates your chromecasting, but I don't know really what to do?

[themury]

Muchas gracias aguardo respuesta como seguir cuando lo reiniciamos de fabrica...

[aazz2100]

I have already factory reset my device 😞

[XZHENG85]

LOL  ME TOO

[chrishowejones]

I also factory reset but you can get the device back on your WiFi (at which point it will eventually receive the update) by changing the date of the phone or device your using to connect to the Chromecast to the 8th March or earlier. Then go through the set up as directed on the screen 

[FahadKhan911]

Try to update your device date to 1st March 2025 and then connect chromecast to get updated.it will be working after taking time to update.

[XZHENG85]

I JUST FACTORY RESET IT. HOW I SET DEVICE BACK? WHERE IS THE INSTRUCIONS?

[Mrbaseball77]

Per rpima cosa devi riassociare il dispositivo all'app google home: per farlo devi impostare una data antecedente all'8 marzo sul dispositivo e poi puoi associare nuovamente la chromecast all'app google home.

Fatto questo dobbiamo aspettare tutti l'aggiornamento da parte di google per ripristinare lo streaming verso il dispositivo.

[Lulu15]

Então nada mais justo q vcs arrumarem o q causou o problema pq eu uso o chromecast como ferramenta de trabalho, estou 2 dias sem conseguir apresentar trabalhos devido este problema e já reinicie mais de 50 vezes , espero q vcs se organizem e tragam a solução o mais rápido possível 

[Furio1]

Da ieri sera Chromecast non si collega più e non di riesce più a configurare,home trova il dispositivo ma non riesce ad autenticarlo.

[Palmi]

Seguo

[Anto18]

Anch'io ho il solito problema. Da ieri sera ha smesso di funzionare.  Ho provato più volte a riconfigurarlo, lo riconosce ma poi esce"impossibile autenticare il dispositivo"

[Alessandro1906]

Ho lo stesso problema. Si verifica solo sulla seconda generazione di Chromecast. Sulla prima versione tutto ok.

[luciasilva92]

O meu tmb está do mesmo jeito des de ontem a noite n está conectando 

[jmimac351]

Can you please send me an Apple TV instead?
