[ManuO]

Hi, same problem here in Argentina. I think they did it intentionally. Me parece q lo hicieron a proposito estos HDP

[luismgz]

Chromecast worked fine for years, but today it stopped working. Tried a reset to factory settings but I just can't complete the setup. The Home app can find the device but, while trying to establish a connection, it indicates that it can't authenticate. 

I tried everything. Unplugging and plugging again, switching WiFi from 2.4 to 5.8, restarting modem, updating Home app... nothing worked.

[musicrowmaniac]

same issue here

[jolxboy]

I reset my phone, device chromecast and wifi router, its 9/03/2025 is a global error problem? 

[Mr_J]

Yes.

[Juanso]

Mismo problema acá. Después del reset aparece el mensaje "No se pudo autenticar" y ya no puedo transmitir contenido desde mí celular, por ejemplo Netflix.

Same problem here: After the reset I get the message "Failed to authenticate" and I can no longer stream content from my phone, for example Netflix.

[Sudaca2025]

Lo mismo aca, desde la tarde que estoy tratando de arreglarlo y nada, tengo dos televisores con chromecast y ninguno anda. Hice todo lo que sugiere el troubleshooting pero no funcionan. No pienso comprar un google TV porque a un CEO se le ocurrio dejar de dar soporte a dispositivos que se usan en miles de hogares, que la chupen y la sigan chupando.

[L0c8lCryt1d]

Got the exact same message, tried restarting the device twice- did nothing, saw a reddit post suggesting that if I clear my phone's Google Play store data and cache that would solve it: it did not, a YouTube tech support video suggested an auto-update may have caused the issue and that going into the device settings and removing that update might solve the issue: plan to try that when my roommate gets home and seeing if that does anything.

[Norma11]

Hubo una actualización hace unos días y desde ahí dejó de autenticar

[kobylia]

Same issue still not resolved?

[Adh1etz]

Not yet

[Bellabeauty]

Same issue here... Nothing is working

[Bellabeauty]

Wonder if this is their way to get us to buy new ones... If that's the case I will go a different route.

[jbaltazar07]

Un usuario de Reddit encontró el problema. EL CERTIFICADO DE LOS DISPOSITIVOS CHROMECAST CADUCÓ el
9 de marzo de 2025 a las 16:44 GMT

Ver hilo: goo.su/GupfEAg

[pablosazycz]

en base a lo que leí, pude lograr lo siguiente.
en un principio como no me funcionaba lo resetee de fabrica, entonces una vez reseteado ni siquiera me dejaba volverlo a configurar. como el problema se basa en la fecha del certificado intermedio lo que hice fue cambiar la fecha de mi celular y ponerlo en 8 de marzo.

una vez logrado pude configurar el chromecast,  y me da señales de vida como si estuviera listo para castear con sus fondos de pantallas.

lamentablemente hasta eso llegue. ojala alguien pueda hacer q funcione!

[Cfben]

I have the same issue. It says:

We couldn't authenticate your Chromecast.

[Queenbeenurg]

Same here. Not sure how to fix it.

[Jesse_yeatts]

Same in Thailand. Factory reset device, redownload home app, even got authentication codes from Google thinking maybe it was problem with my Google account. Updated the address for the device. All to no avail. It's an old device first set up in 2010. Want me to buy a new device? Okay, but how do I know it will work?

[diaVolo]

Don't worry, my friend, my device is from 2018 and the same thing happens to me.

[Kowhaibee]

Same here. Finds it but won't authenticate. 

[Wendyf]

2 of mine are not even in de home app anymore, cant find it either

[cjvz]

Same.

Mine stopped working while I was using ten chromecast. It was in the Netherlands at approximately 20:45 (Timezone UTC +1)

[Wendyf]

Hier ook, ik word er gek van

[MirceaM]

I got yesterday the same issue with e gen 2 Chromecast. It couldn't be added any more to my home using Google home. 

[Wendyf]

Same here, I am in the Netherlands

[SzilardSz]

Hello,

I have this problem too. Is there any solution?

[Sulu]

NO

[vtkellybrown]

same today in New Zealand

[Rishi17]

Still nothing from google on resolution or at least acceptance that they are working on it

Bonjour, 
Merci pour cet article 🙂
Malheureusement il y est précisé " Google déconseille de réinitialiser le Chromecast concerné aux paramètres d'usine", ce que tout le monde a fait  et sans communication de la part de Google c'était évident que l'on tenterait cette manoeuvre... 
Donc que va-t-il se passer maintenant que tout le monde à réinitialiser son Chromecast? 
Ce que je reproche à Google c'est son manque de communication 😤, c'est lamentable!

Bon je vais aller acheter un fire stick mais pas un Chromecast c'est sûr...

[Sulu]

People, looks like Google has 'bricked' the second gen Chromecast. It's little more than hockey puck shaped e-waste now. RIP.  😡

[Cam9]

bonjour
est-ce que cela veut dire qu'il n'y a aucune solution pour ce problème?

[MumTheMightyGod]

Exactly same here ,have done factory reset and now just stuck trying to set up ,but keeps saying it can't communicate with the device ......help! 

[Steve_D]

search google "google chromecast outage"

seems its global outage for Google to resolve

[CarolineAllen]

I have reset my device twice, as it stopped working yesterday, and it keeps telling me it can't authenticate my device.... @Google@Google......please help resolve 

[CarolineAllen]

I am from South Africa.... 

[Omre]

Same Here, been follow all instructions but the result still same..

With notif:

• Could not communicate 

• Could not authenticate

What happened really?

Is it out of date and can not use anymore?
