Same in Romania

Can we get an update or like some sort of an idea of when the problem will possibly be fixed?

[Sbishop215]

I called Google Nest CS this morning and I was basically told they are aware of the situation, there's no time frame for a fix but if and when there is one I'll get an email

[ajith_ea]

Please do let me know when a fix will be rolled out and what are the steps to follow

[Nanneq]

@GoogleNestTeamThanks for acknowledging the issue,
I appreciate that you're working on a fix at the moment, but could you please provide an ETA?
It would save us all having to retry / troubleshoot / constantly scour this forum and the rest of the internet for the anticipated fix.

For the rest of the users here, I can share the findings of a fellow user posted in the Home Automation section - he offers a couple of workarounds there. 
(I've not tried them yet myself, but will be sure to update here once I do).

[Kimlobo]

When can we expect a reply on the next steps also if factory reset is done what is the next option 

[bvavinashgupta]

Is the Issue Fixed?

[Raf0]

Ho due dispositivi chromecast,  ma uno funziona ancora, altro no....come si spiega?

[Hellowin]

Saranno due generazioni differenti, tutti e solo i 2gen e che audio dovrebbero essere afflitti dal bug 

[Mary25]

Bonjour 

Pourquoi ne pas nous avoir envoyé un mail général  sur gmail ou sur votre application Google Home nous informant de la situation, cela m’aurait éviter de tout désinstaller 

Ou de communiquer sur la panne générale au lieu de ça j’ai appris le problème sur un blog informatique 

et à l’heure actuelle sur votre application on nous conseille toujours de désinstaller Google home et de réinitialiser l’appareil 

j’ai essayé de téléphoner à Google France et et de sélectionner chromecast  mais là un disque me demande de rappeler dans les heures d’ouvertures en journée car sur le site de Google France ià Paris à 11 h45 on me dit que vous êtes fermés 

je décide donc de vous appeler et on me dit que quelqu’un va me recontacter d’ici 15 minutes ça fait 2 jours et toujours pas d’appel 

on se replie sur le chat et là au bout d’un long très long moment on me dit patientez on travaille dessus. Sans nous expliquer ce qu’il se passe sans nous donner un  une fourchette de temps 

j’ai des connaissances qui ont récupérés leur chromecast mais ils n’avaient rien désinstallé 

en communiquant sur ce problème dès dimanche ou en arrêtant de diffuser de fausses recommandations sur vos pages et applications on ne serait pas dans cette situation 

pourtant chromecast c’est Google et Google est partout 

je trouve que votre façon de gérer ça, le manque d’informations c’est pas du tout digne d’une société mondiale comme la votre 

bonne journée

Excellent workarounds that will restore Gen2 casting from Android devices and Chrome browser, until Google issues a proper security certificate fix. These instructions will work to restore casting, even if you've already done a factory reset.

Too late, I reset it....

[Nirman]

Hi, 

I have already done factory reset and now it’s completely unusable as it gives an error related authentication. Please suggest how can this be resolved? Just like others I am also facing this issue since Sunday evening.

[JasonCutlerF]

Any fix yet???

[Cosmodrom83]

в ожидании... really need it

[Mali_5150]

 fix yet?

[AjoshiSql]

Hello Google

Do you have any ETA to fix this issue?  

Please provide global ticket number for this issue

[wallergabo]

what should i do? since i already factory reset my chromecast i need help 

[JS45]

Nothing really except hope that google fix it quickly

[aliumv]

Just joining the community of angry chromecast users with an expired certificate

[Ambsmonkey]

Tat of fix??? It's taking a while. A lot of people already have the same issue

[mozartcroissant]

I have the same issue with my Chromecast Audio devices. Could you please notify by email how or when the issue will be solved? Also, it would be even better to put the Chromecast Audio back into production as there is not any alternative from Google that simply outputs audio via a standard stereo plug to an amplifier or HIFI system like the Chromecast audio does. It's so frustrating that such a great device is no longer supported!

[ReyTarzan]

I already reset my device I'm so mad. I have 2 tvs useless.........

[Gerhard123]

When will it happen?

[TamsuiBrother]

I feel relieved to see so many people encounter the same problem as me.

Hahahaha😘

[ReyTarzan]

I thought it was just me!

[Unicast]

Where would be the best place to watch for updates? 

[Anonymous]

I have three Chromcast 3rd GENERATION installed in my house and all of them stopped working on March 09, 2025. Is necessary Google to be aware that the Chromecast failure is not only with 2nd Generation devices.   

[sandhyap]

What is ETC to get this fixed? 

[kiykiy]

早い解決をお願いします。不便で仕方ない。

[StyleDLC]

48 hours and counting while the only "official" communication has been this short, non-scripted, pretty lame message without even recognizing the mistake: "largely known that is due (in part) to Google not checking on the certification end-date". Really insane to think that not a single person said: "Hey, should we use like GOOGLE ALERTS or GOOGLE CALENDAR to see when things end?".
Now, millions of users have an obsolete expensive thing looking to buy a competitor device while Google goes radio-silent without even a "it will be fixed X day".

You can say that is probably one of the worst PR approaches ever.

[Refthoom]

Please fix this as I have 5 Chromecast Audio devices and 1 Chromecast 2gen affected by this.

[mikelord]

Could you send me the fix for a factory reset chromecast 3rd gen? I accidentally panicked and reset it. Now when I check my android wifi settings the chromecast3498.b device says no internet under its name. But all the other devices(laptop, hello Google ) I rebooted the chromecast. I restarted my router. I know have the wifi internet working on all other devices.

My email address is: #

[mikelord]

Hello,

Would you send the reply for the factory reset Chromecast device reconnection to the wifi to setup the Chromecast again to #

[MENAK]

You should have sent email to the users!!! 

[Pierpardo]

The first thing that I've done is resetting...

[Ankurkatiyar]

Please update ASAP as it's affecting daily operation. If not possible we need to migrate to other devices like amazon fire tv stick

[WIlfp]

Posting in order to see the fix to the "can't authenticate" issue.
