How much longer until this is fixed?

[raulfergaeza]

If you need help the bug is in this code line: 

if today() > 03/08/2025

{

        return ('Error Authentication');

}

[MikeyP66]

Before coming here it's obvious the 99% of people have already tried a 'Reset' , thinking they have set something up wrong.  Come on Google... So unlike you to drop the ball.  I have committed to Google Home and have 26 devices... Main reason I went with you is for the 'Chromecast Audio'.  You need to fix this quickly, as you will loose support and also all the recommendations I give for new users.

Will this be fixed with an update? How long do you think is the wait roughly? Weeks, months?

Thank you

[Ryansr1]

Exactly! They don't even inform of a possible ETA for the fix. 

[Inimini]

The warning not to factory reset comes too late... You try everything when something doesn't work. Unfortunately not the first time either...

[ChromecastUser2]

Set the date on your smartphone back to march 7th. Then install your Chromecast through Google Home. It won't work for steaming anyway but it is connected to your net ready to receive the fix

[MarieKim65]

So is everyone still out 

yep because I didn’t know about it I factory reset my device 

[MarieKim65]

So is everyone still out ?

oh yeah I’m one the probably 100’s that reset their devices because I didn’t know  the problem was google 

how long until the problem is fixed ? this is my only way to watch TV

[Kristy4178]

How will we be notified of what to do next?

[osamu]

Please resolve this issue as soon as possible. I am in so much trouble.

[Ryansr1]

Wish it can be fixed soon.

[Alfred555]

I will never buy any GOOGLE products again

[SanderL]

I already returned to factory settings my Chromecast Audio. Tell me what I have to do to turn it back to normal?

[Mardecel]

GEROU VÁRIOS PROBLEMAS PARA MIM, VÁRIAS PESSOAS QUE RECOMENDAVA E RECOMENDEI ... 

TODOS ME XINGARAM, RECLAMARAM E QUEREM SOLUÇÃO DE MIM, APENAS UM USUÁRIO QUE AMAVA O CHROMECAST...

ESTOU MUITO TRISTE E SEM CHÃO 😢 😞 

RECLAMEI MUITOS ANOS DESSA INTENSAS ATUALIZAÇÕES CONSTANTES, IRRITANTES E Desqualificadas... 

A BOMBA 💣 ESTOUROU AGORA E AO INVEZ DE RETIRAR A ULTIMA ATUALIZAÇÃO E MANTER A ULTIMA FUNCIONAL ATIVA ... NÃO ESTA QUEIMANDO O NOME DA GOOGLE...

ESTOU FRUSTRADO...

ALÉM DA RAIVA DE MAIS DE 24 HORA ...

PARABÉNS!

[jessst]

Doesn’t feel like your response is urgent enough for how much of an issue this is

[vibeketoemte]

It's all about the money by now, it seems highly unlikely that a billion dollar company like Google would, in 2025, need several days to fix this, with no information provided. 

Most likely, they're awaiting the customers to take matters into their own hands, buying a new Chromecast and stop complaining about the current one. 

Can anyone recommend a new streaming device, not made by Google?

[DanielSibisan]

I have several Chromecast Audios conected on classic Stereo Systems. If Google will no longer support the Chromecast Audio then what? Maybe you should make it open-source? It will be a pity to throw away such a simple, beautiful, usefull and High Res equipment for some Low Res active speakers or super expensive equipment from other brands... I use Google everywhere, my phone is a Pixel... Google is simple, efficient and performant. Please do not let us down!

[Mohsin9129]

Google has acknowledged the problem and is actively working on a fix. In the meantime, some users have found a temporary workaround by resetting their Chromecast and manually setting their phone's date to a day before the issue began (prior to March 9, 2025). This method has allowed them to add the device back using the Google Home app.

[Robynandtinker]

The same thing happened to me last night, having the same issue today. It’s really annoying. Would be good to know if it will be fixed??? Perhaps upgrading to the new chrome cast would work? I feel like everyone should be given new ones. Would be good to have been notified 

[Robynandtinker]

Hello, 

could you please advise when this will be fixed? 
thanks 

[Terrie]

The previous help info says to factory reset and can't authenticate and now you're saying - in red - don't factory reset? Please help 

[ChromecastUser2]

Please respond to us once this issue is resolved.

[PaulKlinkhamer]

Please FIX THIS if you want your customers to not boycot Google. There are 100k Chromecast users that can’t use there product for 2 days now… that’s not oké for such a big company 😱

[Presidente_75]

Ciao a tutti

Posto una soluzione temporanea per chi avesse fatto il reset di fabbrica del dispositivo.
Entrare nelle impostazioni dello smartphone, cambiare manualmente la data con una antecedente l'8 marzo.
Aprire l'app Google Home e configurare ora chromecast che viene rilevato e può essere riconnesso alla rete internet.
Lo streaming verso Chromecast non funzionerà comunque, ma per lo meno, appena verrà rilasciato un aggiornamento, il dispositivo riuscirà ad aggiornarsi

[Super_Dave_Osb]

Do you need to replace your Chromecast or are you finally going to fix it? It's getting long without an answer...

[Evak]

Inmiddels zijn we 24 uur verder. Weten we al hoeveel tijd Google nodig heeft om zoiets simpels te verhelpen? 

[EmD]

Ummm, so how will we know when the problem is fixed? And if we already did a factory reset because this information wasn't glaringly obvious when Chromecast went down? If you go to troubleshooting it literally says to factory reset.....

[SLaursen]

Have reset my cromecast - sorry, please send instructions to getting started again.   #

[Pucksterv]

Replying so I can stay updated on this issue. Unfortunately I already reset my device to factory reset.... Hoping it will work soon 

[Anonymous]

Nu är det väl bara att vänta på information, när detta är åtgärdat. Jag har också fabriksåterställt den. 

[letoute]

Shall we all switch to other browser, Hotmail or Apple mail,  other search engine then google, let's say Bing..... ??? Let 's see how this affect their advertising income......    Get it fixed!!!  You can still buy them new on E-bay (Chromecast audio).....  WTF.....      I use 3 of them.... connected with optical cable to decent Hifi Amplifiers and speakers....  No interest in crappy bluetooth speakers and sound.....

[Nimitha]

I did  the rest , now facing the issue " we couldnt authenticate your Chromecast please visit support"

[John9999]

Prior to this (very late) update, your own troubleshooting steps instruct you to factory reset as one of the steps!

[Bp55]

For those of us who factory reset before coming here, what do we do now? 

[Pucksterv]

For people that have factory reset, here is a solution: https://www.theregister.com/2025/03/10/google_chromecast_outage/

Basically set your setup device (phone) to before March 9 (before the issue started) and try to set up through home. It won't fix the actual issue (you still can't cast) but at least it won't be in the setup anymore 

[BobbiFrances]

Is there any update?

[Bordigles]

Another unhappy Chromecast Audio owner here. Please fix this ASAP

[Black60Dog]

Thanks when are you planning on doing the instructions for ones that have been reset

[Ronaldom]

Bom dia,  essa informação já veio de forma tarde, pois,  já restaurei as configurações de fábrica no domingo. Como proceder?? Quais as medidas que vcs irão adotar para NÃO prejudicar quem restaurou as configurações de fábrica??
