The google home app literally said to restore the device if unable to connect 😭

I recently changed my broadband provider.  One of my Chromecasts set up no problem, but the other one just generates this message

tv may be set up, but we could not communicate with it from your iPhone. Make sure that you have enabled local network access in your privacy settings and try again. 

I have done all the checks recommended but gertting nowhere.

Any ideas - can a chromecast just die and changing the network was an unfortunate coincidence?

[fahadwaheed]

Hey! Chromecast is facing a worldwide issue atm and google is fixing it, so we can only wait.

[JackHoff]

Everyone who has been affected by this should get a new Chromecast. Thank you. 

[Me888]

Changing the date on your phone doesn't work - I've tried it with 7 March and 8 March and multiple attempts to add the device back in my Google Home app have been unsuccessful. This is simply not good enough Google.

[Claudioivanmesa]

Still no fix, this is Chinese crap quality, if no fix is released i am never again buying a google device, feels like an on purpose move to get us to buy a new device, this is as dirty as it gets. 

[Zub]

Is this some sort of joke from a multi trillion dollar world wide company?

[BMD1]

I would like the resolve to cheers 

[Alfranco17]

I did the factory reset before finding this suggestion. There was a solution to the factory reset that now is gone. I came back to thank the original post, but since I can't find it, here's the procedure to undo factory reset (does not fix the main issue, but at least I see pictures instead of a blank screen) :

A) change your phone date to march 8 or before (when the certificate was working).

B) add your device with Google home.

You won't be able to cast, but you will undo the factory reset. 

[Me888]

I've done that multiple times yesterday and today and it still won't let me at the device back to Google Home.

Here's a clever set of workarounds that will restore Gen2 casting from Android devices and Chrome browser. Worked for me. Not perfect, but it will suffice until Google issues a proper security certificate fix.

[Mleyson]

Will there be support for if you have already reset your device?

[Ticonn11]

If it's an expired certificate then the solution should be easy right?  Just change the date on your TV system settings to before the ticket expired, problem solved. 

[Rosieffs]

How do we get updated when this is fixed? Do you message customers?

[geici_dias]

Olá, tudo bem?

Segui todas as instruções que vocês me passaram: reiniciei meu Chromecast, refiz as etapas de configuração e confirmei que ele está conectado corretamente à internet, na mesma rede Wi-Fi, com o Bluetooth ligado. O dispositivo é encontrado, mas, ao tentar conectar e inserir o código de quatro letras, ele trava e não avança. Aparece uma mensagem informando que não foi possível conectar o Cromocast. Acesse suporte... para resolver o problema. No dia 10/03/2025, um atendente informou que o problema era geral, mas que seria resolvido até 11/03/2025 ao meio-dia. No entanto, mesmo seguindo as instruções, ainda não consegui configurar meu Chromecast. Tentei contato novamente, mas não obtive resposta. Gostaria de saber o que posso fazer para resolver esse problema?  Caso o aparelho não volte a funcionar, peço que nos avisem para que possamos buscar alternativas. Se puderem me ajudar, agradeço desde já. Aguardo um retorno. Obrigada.

No autentifica el Chromecast, ya lo reinicie desenchufe, todos los pasos y no funciona y no he recibido ayuda desde soporte que donde me indican que me dirija 

[Marianella]

Existe un error de autenticación en los dispositivos, quisiera saber si firman parte de la obsolescencis o están trabajando en la falla.

[Oacruzh74]

Por favor indicarnos si estan trabajando en la falla y que pasos seguir

[Marpeluti]

Me esta pasando lo mismo. Restablecí a fabrica el chromecast, pero no auntentifica. Será que este aparato de 2 generación ya lo vuelvan obsoleto adrede? Para comprar uno nuevo? 

[saralm480]

No consigo configurar Google home. Reconoce el dispositivo y antes de finalizar me pide que de acceso a la red local, y aunque está dado, no termina de configurar el chromecast, no puedo enviar la pantalla o app a mi televisor. 

[Smee]

Would really appreciate some more regular updates. Can't believe the timing of this. Have just had major surgery & I'm restricted to bed rest, with no TV for 2 days. Fantastic. Don't even have anyone that could go out & buy an updated version. Probably too expensive anyway. Or is that their plan all along? Hmmmm 

[foofiebeast]

This is also affecting my gen 1 chromecast.

[Ryan122]

Não quer conectar a minha tv sony

[BrendaFerrari]

Não foi possível estabelecer comunicação com o Chromencast! É a msg que aparece pra mi desde Domingo!! Google não vai fazer nada sobre isso?? 

[geoffmarton]

Well, they don't have the label anymore, but this is specifically Chromecast Audio. Crazy to me that they stopped making this device; it's the only thing that saves old stereo systems and other audio devices from the removal of the headphone jack in every modern phone.

Suddenly, I couldn't cast to my beloved Chromecast Audio. Just wouldn't do it. 

Here's what I've done:
* Reboot the device
* Reboot my phone (Pixel 9 Pro, software has been updated)
* Reboot the wifi router (TP Link Deco mesh)
* Remove the Chromecast Audio from the home, since it wasn't being recognized
* Attempted to re-add the CA device
* Initially, I got a message that said "cannot authenticate device."
* Later, it couldn't find it at all
* Tried both 2.4 and 5ghz bands of router; most of the time, device is found on either band, 5ghz simply generates the error more quickly

Please help. No way to get audio into my electric drum brain without a device like this working, it's older and only has physical lines in.

[MMx]

My Chromecast has failed to function for going on to 3 days. When I try to cast thru the browser the connection window is dimmed, and says "Available for specific video sites", but doesn't function for any sites. 

If this continues much longer without any acknowledgement from Google that they are working on the problem and give an estimated time for repair I will be forced to using a different device found on Amazon that allows direct connection from any device to the TV:  https://tinyurl.com/mr3ymze3

[Soeli5555]

Não estou conseguindo conectar na tv, o app está falando q está com erro

[dnpegs]

Day 4 in new Zealand.  Who would have thought the biggest IT company messed up and taking days to fix.

Bet it wong be ready by the weekend,  paying for subscriptions i cant cast to TV.

great work.

[Kat20]

I'm exactly in the same position. Also in NZ, feeling very annoyed I'm paying subscriptions and can't watch anything!

[tonywyant]

Any update  on this? This is my only  streaming device, so  without it I have  to  find better things  to  do,  like  look for  an alternative  deivce to the Chromecast,  but  do I need to  buy  something else [not from you], or can I  expect a  fix in the next day or so?

[Cryss]

O chromecast desvinculou sozinho. E agora não quer mais espelhar o telefone. Tentei reconfigurar o app, mas não consegui pois diz que não consegue autenticar o aparelho.

[Parthipan]

I have same problem. I am using chromcast gen 2. I already reseted. Now can't add my device. Please inform this case if issue solved. 

[Hreg123]

I too am having this issue

[mariam123]

when will this problem be solved?

[Lyfted1]

This is nonsense! All your help articles state to perform a factory reset!! I too would suggest a new Chromecast be sent to those of us who are experiencing this issue. As big of a company as you are it shouldn't be hard to issue a statement on your site along with an application to have a new device sent to us free of charge. I haven't been able to watch anything for almost 3 days now and feel like I'm being taken advantage of by Google. Smh

[MayraFaneites09]

Estou sem TV desde do dia 09/03 devido essa pane no app Google home e no aparelho chromecast. Se dizem tão inovadores e tecnológicos que não fizeram atualização do sistema.Ou é mais uma jogada para forçar a comprar um novo produto.

[Cristianee2410]

Espero que não. Preciso do meu de volta. Também estou sem desde segunda. Aparece uma mensagem de erro na autenticação.... affff

[Deb_74]

When will this be fixed or are you going to make us buy a smart TV? I am not happy at all.  

[TrishJ]

I was advised by the Google customer care team to factory reset, which I did. How much longer will it be till there is help for those of us that have done a factory reset?
