If we do factory reset, someone in the community mentioned what to do, here is what I followed the same and got success. Change in your settings , auto date off, change date to Mar 1st and then add chromecast device to Home app, it should work and doesn't give the error "we couldn'tauthenticateyour chromecast device." Once device is connected then with in few minutes i see chromecast updated and its back to working. Yay

Los dispositivos que estan desconectados como van a recibir la actualizacion? O sea los que fueron reiniciadoa

[Marianamulata32]

El que restaursate tenes que hacer

1. Cambiar la fecha a tu movil.

2. Configuarr desde Google home , una vez actualizado

3. Vuelves a cambiar la fecha a la actual y listo puedes volver a transmitir. A mi me funcionó . Suerte

[seljukinha811]

Entendi,mas quando tento usar o dispositivo é pedido para que seja configurado,sigo todos os passos,mas no momento que pede a senha do wi-fi da senha incorreta,mas a senha está correta. Então o que faço?

Fico no aguardo de um retorno.

Obrigada

O meu continua dizendo que não foi possível estabelecer a comunicação entre o Chromecast e o meu dispositivo.  Desde segunda que não consigo

If you have done a factory reset and it is not working. Then take a device on which you set the date back a year. Try to connect the chromecast. It will connect, you can setup your network. It will get the Google updates and you are back on line. Set the time back to normal on the device you used to do the setup.

My Chromecast received an update just now and it started working again! Thank you GoogleNestTeam!

[thermoMoe]

Great, the two Chromecast Audio devices i did not factory reset are back online; however, the one that I did reset still cannot be connected to by Home. Hopefully that issue will be figured out soonish.

• change the date to May, 8th on your phone or the device on which you use Home
• Search for a new device, relink your Chromecast (it will restart it after a couple of steps)
• When Home displays the "update takes longer than expected", reset the clock on your Home's device to automatic.
• You can cast

I just did it, it works 

[Huepaz]

No way on an iPhone 

[Anonymous]

March, not may. 

[Ell3]

If you had reset your device:

• change the date to May, 8th on your phone or the device on which you use Home
• Search for a new device, relink your Chromecast (it will restart it after a couple of steps)
• When Home displays the "update takes longer than expected", reset the clock on your Home's device to automatic.
• You can cast

I just did it, it works 

[Huepaz]

It doesn’t work on an iPhone, how do you suppose to change the date? there is no way 

[Ell3]

Weird it worked on the iPad.

You can check this link (I haven't): https://support.apple.com/en-gb/guide/iphone/iph65f82af3e/ios

If it doesn't help, I'll check when back home to give you the step by step 

[Nest75]

May 8 ? 2025 or ?

[Ell3]

Any date anterior to May 9th, 2025

[Huepaz]

There are some people saying that changing date on the phone and reinstalling the app the problem will be solved ¿ how do you change that on an iPhone??

[Marianamulata32]

hay veces que en algunos iphone no te deja cambiar la hora de manera manual. busca un dispositivo android y ahi si vuelve hacer la instalacion. suerte.

I have 2 CCAs and a CC. One of the CCAs started working. Probably got the fix/patch/whatever. Athens-Greece. There is hope ppl

[dmopont]

Now I can't mirror my cellphone screen anymore.... it was working before the bug

No point fixing one thing and not the other.

[thais2512Messia]

Olá, espero que esse problema se resolva logo, pois o certo seria se o Google tivesse nos notificados, entretanto só fui saber pois fui pesquisar alguma forma de atualizar meu Chromecast

[Ideid]

I factory reset before i knew of this problem.  Please fix soon

[Nest75]

I factory reset one of the CC and that one is working, the other was not factory reset and still not working (it say can not see the CC on the network) ?

[Mrtax2005]

Hello….Thank for cc 2gen fix but for cc 1gen nothing more?

[Anonymous]

I have a Chromecast I'm trying to set up

[mirtacoppola344]

Muchas gracias

[joaop]

It's working again! Thanks.

[Efily]

Pra quem redefiniu, mudar a data do seu celular pra configurar resolve o erro. O meu até pediu atualização logo depois. Falta só eles consertarem a transmissão 

[Ddlittle]

you guys are sloooooooooooooowwwwww. I reset device and when setting up, it says it’s connected to the network, then it says it can’t communicate with my device.  I tried iPhone and iPad. Same result. Also, tried connecting to my office and home networks.  It’s college basketball playoffs.  Cmon guys.  I want to watch in my den on the big tv.

[Wsf]

You still having this issue? I’m facing the same problem 

[Siddzz]

Just reverse the date of ur phone 10 days and setup the device again this will work
