Same problem 

The setup is interrupted with the message that my chromecast which worked perfectly until march 8 2025 is no longer authenticated 

[Cesar2son]

Yo tambien tengo el misma problema con mi chromecast 

[Elzassis]

Exatamente a mesma data que começou a aparecer esse bug no meu 08 de março de 2025.

[SergioN]

I've had the same problem since yesterday.

[Agonort2010]

ME TOO

[Pw1982]

Same problem amateur hour for Google looks like we will have to move to Apple if Google doesn't fix the most simple problem.

[ravikiran]

Dear Team,

Chrome cast not getting connected...error showing as ' we couldn't authenticate your Chromecast...support google'

Please check and help me to resolve the error...

[Mandoman]

Like everyone else I am experiencing problems and am currently unable to cast from my phone/tablet.

Unfortunately i have already tried to do a full reset as I was not aware that this was inadvisable. 

I'm aware that Google are currently trying to fix the problem and wondered whether there was any way to create an alert to advise me when the fix is launched so that I can try to get back to casting?

[asterisc]

I'm in the same boat as you. Did you get to the page where it trys to connect to wifi and then eventually goes back to the get the app page?

[NizhoniNight]

If you factory reset you can get your chromecast back on Google home by setting your phone/tablet date to a date before march 9th then once it's in set it back to actual date. You still can't cast anything before they come with a fix but at least you can see the Chromecast again while waiting for the fix to be sent out from google

[Syllmae88]

My Chromecast stopped working Sunday evening 🥺😔😔😔 I'm going crazy I'm good at technology but nothing worked

I even uninstalled my Home Google but NOTHING WORKED! CAN SOMEONE TELL DO I NEED TO BUY ANOTHER ONE?

I used this for years of not a decade

It explains that Google is aware of the issue and are working on a fix.  In the meantime, do not factory reset if you haven't already, at there may be extra steps to go through when they do get a fix. 

I'm going just as crazy as you are, hang in there.

[Dracodepressus]

Igual, yo salí de viaje de trabajo y hoy martes, que quiero disfrutar de Chromecast, me encuentro con la sorpresa, de que mi dispositivo no se puede verificar, no cabe duda, cada que actualizan algo, en lugar de mejorar, mandan todo ala mier@#$$, espero que nunca Google saque, robots autónomos, para ayuda del ser humano, porque de otra forma, todas esas películas que hemos visto se van a volver, mera realidad 

[Betoraf]

I appreciate your concern and attention as it deserves, but my patience and that of almost everyone is running out, but mine worries me and I am a very patient person, give a quick solution or accept that there is none, we will organize and see what end we give to all this, this is translated with your translator and I hope you understand it, the next message will be in Chinese, Japanese, Aramaic and so on until you understand it, greetings

[jessyfu]

Any updates with the issue with the chromecast? It has been 2 days without been able to use its.

Thanks.

[Casa154]

O meu também está assim a 2 dias!

[ameli1986]

[Setitup]

When i try to connect to chromecast I get a pop up that says Connect to device failed.  Failed to connect to selected device.  Please try again later. How do u fix it?

[Joasb]

• Where can I find the instructions to set my device back up? I have factory reset my device

[Paul-Maes]

Het lukt niet om uw Chromecast te verifiëren. Kunt u mij helpen wat er aan de hand is?

[Wilma2]

Dat is bij ons al 3 dagen zo, Google zegt er mee bezig te zijn maar het heeft klaarblijkelijk geen prioriteit....zelf heb ik net mijn laptop met een hdmi kabel aan de tv gehangen zodat we wel iets kunnen kijken via NPO start of bijv Netflix. We wachten het verloop maar rustig af denk ik.....

[Eric71]

Hier ook problemen met verifiëren.

Het enige wat je kan doen is een klacht sturen en hopen dat het snel verholpen wordt.

[Ace666]

In the meantime new generation of google chromecasts are sold, excellent move Google. Not buying google products with programmed obsolescence anymore.

My Chromecast didn't  update latest firmware

[Pavelardi]

I’ve used this device for years. It stopped working recently. I tried basic troubleshooting, reset the device and tried to add it back.Everything goes well, including appearing to connect to local wifi. And then it fails. I get a connected image, but the message, something went wrong  Condo speaker may be set up, but we could not communicate with it from your iPad. Make sure that you have enabled local network access in your iPad’s privacy settings. Then try again.

Any thoughts greatly appreciated. Thanks.

[sogabbs]

Hi I have been having the  exact same issue. There is a system wide issue that has impacted many users. They told me that they are working on fixing the problem.  They said not to factory reset but that was one of the first things I had done based on their suggested steps. Hopefully they will be able to figure out the issue soon! Mine has been down since Sunday 

[Pavelardi]

Thanks. Mine has been down since Sunday as well. I actually thought about getting a new one but I will wait to see what happens. I did factory reset mine but it did no good. Back to the same place. 

[Spekski66]

I've reset my Chromecast by addin' it back to the Home app, I have set my cellphone to March, 7th and then started the procedure to connect it to the home Wifi, now it's back on my TV and on the Wifi, I think that's better when Google fixes this.

Don't forget to put your cellphone back to the correct date and time.

[Mercedes13]

Still waiting, I just tried to cast, but nothing yet. 

[Stef69]

Je viens de mettre mon téléphone portable sur le 3 mars. J'ai réussi à reconnecter mon chromecast. Mais rien ne fonctionne dessus. Impossible de caster la tv... que faut-il faire d'autre ? Merci.

[WCR]

De repente el Chromecast ha dejado de funcionar.Yo he reiniciado el dispositivo y ahora el sistema a través de Google home me señala que el dispositivo no se puede autenticar. Me pueden decir cómo volver a restablecerlo?

[paco1]

no hagas nada estamos a la esbera de big G que lo solucione

[Mgr100]

Ya llevan 2 días…

[Fcampos]

Será que foi pane geral , o meu tá assim a dois dias 

[mahendraptl4]

Chrome cast not connected to wifi

[Suelennnn]

Me paso ayer, hoy me dice que no se pudo autenticar mi chromecast

[slawomir1]

Google home can not connect with Chromecast 2 neither with Chromecast audio

[TimBob]

There's a valid workaround on another online community: https://www.reddit.com/r/Chromecast/s/xetx9OH4DA

[Sylviamarfer]

Buenos días, no tengo ni idea que modelo es mi chromecast, lo compre hace mil años. Acabo de hablar con un agente y me dice que escriba aquí para poder enterarme cuando esté disponible la nueva actualización porque si dejo mi chromecast enchufado a mi TV, la apago y automáticamente se enciende sola y va a la pantalla del chromecast y claro no voy a tener todo el día el tv encendido.

Espero que no tarde en resolverse el problema, somos muchos afectados y le deberían se dar prioridad máxima. Muchas gracias de antemano. 

[Sylviamarfer]

Por cierto el error inicial no es que se encienda la tv si no que ya no puedo conectar mi chromecast al WiFi. Gracias
