Me too. Good to know it's a general error, hopefully they'll resolve it soon!

[vjrocks87]

i fear their is any intent to resolve, as this is a old device working fine they might want to sell new ones.. 😄

[Leesakat]

Yeah this is some BS. I'm having the same problem, day two. I saw in the news they are trying to work it out so fingers crossed.

[gi70]

I am from Brazil and have never experienced this issue. I've done everything they advise in the HELP section but it simply won't authenticate. It isn't good for Google if they're trying to increase sales of a new version of the Chromecast devices.. I would never buy a new one tho

[Irawanf]

I am from Indonesia, also have the same problem.
So it's a global error.
If its a firmware error, how to update the new firmware if it fixed since I cannot connect to the chromecast device from google home ?

See this solution from a reddit member:

[Jimlaad]

This temporary solution seems to have worked for me, thanks for sharing 🙂

[AtRebecca2025]

Have not used for a few days, would not work for me March 9th. Still not working. Seems like a Google issue. Just have to wait for them to fix this date authentification problem. 

[Jimlaad]

Same error in Netherlands since yesterday, looks like Google is trying to make even more money. They better fix this issue instead of destroying 100's of thousands of devices 😞

[HNcoach]

Same here. /Sweden

[Jenlesaca]

Same here i Norway. I thought something was wrong on our part so I did a factory reset. But it just keep on saying we cannot authenticate your device... Hope they can fix this soon

[Mstahl]

Same in Israel. 

Classic Google: who needs QA?  Let your users do the testing.  

[Tameracabrera]

Chromcast stopped working without cause did factory reset as instructed and now can't authenticate

[ManfredM]

Chromecast is not working aymore.

Nog damage, reset doens't workt etc.

[ArthurEgide]

I did a factory reset before I had access to this statement. What should I do?

[iAndroid]

same situation till now, waiting for a fix 

[ahoopi]

My device was already reset attempting to fix this problem.  Now what?

[Magneticorps]

Le Chromecast ne finie pas sa configuration et donc n'est pas utilisable.

[Suhaki]

Bonjour, j'ai le.meme souci

[Magneticorps]

Il y a plusieurs post sur le sujet qui remontent en gros à hier (9/03/2025)

Le chromecast n'etait plus en liaison wifi et avait disparu des objets de google home.

En tenant de le réinitialiser, pour le remonter , la reconnection s'arrete a l'authentification le chromecast presente le pin code d'authentification et que Google home ne presente pas de fenetre de saisie du pin code.

La procedure part en time out et dit que l'authentification a échoué...

[alebensadon]

Since yesterday, many users with Chromecast devices reported an error when trying to configure the device in the Home app.
The error is authentication.
Something like this: ""Your Chromecast could not be authenticated. Go to support.google.com/chromecast for more help troubleshooting this issue."
It is a global problem for Google with Chromecast devices.
Error reports have been reported from several countries on 5 continents. 
Probably due to a firmware error.
Let's hope they solve it soon.

[letoute]

Idem.... al my three chromecast-audio are out!  😡

[Magneticorps]

Exactly th same.

No meaning to put on google home the autenthification pin code present by the chromecast aim to finish thé appariement.

[Delphine65]

Bonjour, depuis le 09/03/25 association chromecast impossible. Message chromecast non authentifié malgré toutes les manipulations possibles y compris réinitialisation d'usine 

[KennethOresved]

Google home finds chromecast- ID but cannot connect. No network suggestions during setup, only chromecast in the list of networks. Does not proceed to show an ID that is usually created during setup with Letter, number, Letter, Number that is usually shown when Google home connects Chromecast.

[Slavitch]

You've bricked hundreds of thousands of devices Certificate issues are almost impossible to solve without opening security holes.  Google will need to replace every device impacted at their cost.  

[Googl3]

Please make my Chromecast work

It is not connecting because it says Chromecast could not be verified and it is outdated

@Google1 @admin 

[Dorinda]

I have the same problem 

[Thiago_Neto]

Same here in Brazil When trying to connect the device to the internet, an error appears stating that the device cannot be authenticated correctly on the local 2.4g network.

[nemoguardian]

Desde anoche no puedo conectar mi Chromecast para enviar contenido ni volviendo a valores de fabrica, no atentica  o no le da las credenciales de la wifi para enlazar correctamente y da error.

[JMRosario]

Thank you very much for the proactive notice! 

[Maxwel]

Tem alguma previsão? Estou off a 2 dias🤦

[Thiago_Neto]

When trying to connect the device to the internet, an error appears stating that the device cannot be authenticated correctly on the local 2.4g network.

[mgalvish]

Hello, I have already reset the device to factory settings, please give instructions to reconfigure it.

[Grahamfish]

It's been well over a day now since all of my Chromecast connected TVs have stopped working. Tried the date rollback on my phone, but all TVs are still showing "offline" in the Google Home app. We need a fix now or an indication of how you intend to replace our devices Google...

[Cc2025]

PROBE ESTA SOLUCION DE CAMBIAR FECHA DEL CELU A 5 DE MARZO Y FUNCIONA 

[ahoopi]

I was able to reset the ChromeCast by setting the date back to Wednesday, March 5, 2025. Setup completed and the device is back online, but it still won't cast content from most of my apps.  Still broken, but not entirely a brick.
