I have exactly the same problem, before past weekend.

I'm waiting for a Google home actualitation or something

[Derri]

Same issue. Changing the date seems work to connect the chromecast to the WiFi but I cannot cast netflix or YouTube.. 

[Meanbeannn]

Same here... I have THREE in my house.. One of them started doing this BS a few days ago. Tried everything. NOTHING works... weird thing, when I went to check on it again after leaving it for sometime It was showing the display (the background pictures chromecast shows on the TV) but with a message saying to Restart the display :S.  My other 2 work just fine. There is nothing like the chromecast...Google discontinued them on their own. You now have to pay $129 for the upgrade with the new box thing its called Google tv or something 

[Octj1968]

I can't log into now TV app on Google streamer , despite getting it on my app list? Any help?

[Esther3]

Respondiendo al aviso de Google con respecto a la caída de los Chromecast de segunda generación, avisaron tarde que no se debía restaurar de fábrica, ya que a todos los usuarios a los que nos empezó a pasar antes del aviso,se nos llevó a Un solucionador de problemas de Google donde lo primero que recomiendan es restaurar de fábrica El aparato. Es una vergüenza que pase esto! Encima pensando que se me había estropeado sin más, me compré otro! Quién se hace cargo de estos gastos adicionales? Modo indignada ON

[edulongo59]

Arrénglenlo de una vez, es una vergüenza, son los creadores del dispositivo, y nosotros las víctimas 

[freddy_matute]

Yo también soy uno de los usuarios del chromecast q al presentarse el problema inicial, reinicie el dispositivo, mismo q al momento previo a pedir la clave del wifi, indica q hay un problema y simplemente se queda ahí, sin conectarse a ninguna red ni nada....queda en el "limbo" sin importar cuantas veces se lo reinicie...ojala y pronto llegue la solución a este problema global, xq estoy seguro q somos miles los q lo tenemos...

[Oscar43]

Hola soy otro afectado me pasa exactamente lo mismo con dos aparatos chromecast, desde el pasado domingo me resulta imposible conectarlos..me sorprende que cuando busca red wifi home me dice que intenta conectarse en una red temporal que corresponde al numero de chromecast.os pasa lo mismo..quizás nunca me habia fijado pero cuando voy ajustes de mi telefono redes wifi alli juraria anteriormente no podia visualizar una red chormecast seguida de un número

[MaiconMatheus]

Chormecast voltou funcionar, pessoal!

[Stef69]

Comment ? Il ne fonctionne toujours pas chez moi.

[Tuca]

Os  meus não voltaram. Não consigo autenticar 

[ousamataha]

Hi Team,

I am facing issue with my chromecast 2nd generation not connect to my TV and it show me that the firmware outdated, i want to know when available new firmware and the issue now for one week happened last sunday .

Regards       

[Wibban74]

Ok so a fix is in rollout and the device has to be connected. I removed my Chromecast from the homeapp when it was down and couldn’t install it again until I manually changed the date to prior March 9th. But now it doesn’t show in the google homeapp unless I manually change the date again to March 8th. Will the fix still work? Will my Chromecast update automatically?

DA DOMENICA 9/3/25 IL MIO CHROMECAST NON SI COLLEGA PIU' ALLA TV. HO PROVATO A FARE ANCHE IL RESET DI FABBRICA ED ORA NON SI RIESCE PIU' NEANCHE A CONNETTERE AL WI-FI. STO USANDO PER LA CONFIGURAZIONE GOOGLE HOME, MA NON RIESCE A STABILIRE LA CONNESSIONE AL DISPOSITIVO PER CUI NON VA A BUON FINE. PER FAVORE AIUTATEMI. GRAZIE

[The_quick]

Ciao Mauro, anche io avevo lo stesso problema.  Oggi ho seguito il suggerimento di altri utenti e ho impostato la data del mio smartphone al 7 marzo 2025. Poi ho seguito la normale procedura di installazione del chromecast da google home che finalmente è andata a buon fine. A quel punto ho rimesso la data automatica e riavviato smartphone e chromecast (per sicurezza). Ora tutto funziona nuovamente. 

[Anonymous]

Grazie mille ha funzionato!!!!

[JamesS74]

Seems pretty impossible that this was a "mistake or oversight" You have some of the world's smarted software engineers working for you, and not a single one remembered to re-new a certificate??   That's like saying...  Sorry, we forgot to renew our domain name, and the website is gone.  Get your **bleep** together, before I dump all 30 devices and switch to Alexa !!!   I'm tired of this **bleep**. 

[Novyz]

yeah for real google is stupid as **bleep** they even had like 10 years before the certificate could expire a normal firmware update could have prevented all this **bleep**

[Xenofon]

Dear team,

Already reset Chromecast 2nd Gen for 2 times after problem with authentication.

Could this Chromecast backed up?

Thank you

[Novyz]

It's a problem that should have never happened, but for some reason a multibillion-dollar company like Google forgot to renew a certificate, so all Chromecasts are **bleep**ed. The only thing you can do is wait the factory reset may have complicated a future fix tho.

[NizhoniNight]

Worldwide problem. Since you factory reset (google posted to not factory reset, 24 hours after the problem started and to just wait for a fix from them) you can reconnect by setting your phone's date to a date before march 9th (march 8th or previous) then normal setup, then once connected reset to the correct date. You still won't be able to actually cast before Google fixes the problem though

[CharlieMiddle]

Hands up if you think Google "bricked" the 2nd gen Chromecasts on purpose? 

I bet there's someone high up watching sales of the current generation increasing and decided not to fix the issue! 🤷🏻‍♂️🤷🏻‍♂️

[Novyz]

It's a problem that should have never happened, but for some reason a multibillion-dollar company like Google forgot to renew a certificate, so all Chromecasts are **bleep**ed too strange.

[Narkol3ptic]

YEP! why keep offering support for old devices. Roll out the new ones that are more expensive. That's capitalism right? 🙂 

[Honamom]

Was kind of thinking this...because the fix is such a hassle. When I originally set up my Chromecast no APP was needed and I could use any device to cast. Do I want to get the next generation though? Not if it requires downloading apps like a firestick. Firestick is cheaper 

[Gigi12]

It just stopped working- what is the issue pls 

[Spellbounding]

Someone forgot to renew the certificate for the firmware in the device, and over 100 million 2nd Gen devices have been offline since Sunday, ours included

[Narkol3ptic]

Or Google is just going to drop support for the first couple gen devices.

[JamieSB]

Is Google drops support for this device. I will remove every Google product I have

Estou tentando configurar o chromecast porém no aplicativo Home aparece a seguinte mensagem: "Não foi possível autenticar o chromecast".

Já reiniciei o aparelho, Wi-Fi, celular e não sei mais o que fazer, alguém poderia me auxiliar?

[Maryelleferreir]

Estou com mesmo problema e não sai disso 

[Maryelleferreir]

• O Chromecast enfrenta falhas por expiração de um certificado intermediário em 09/03/2025, resultando em erros de autenticação.
• O Google reconhece o problema e trabalha na correção, desaconselhando restaurar as configurações de fábrica do dispositivo.
