If you have done a factory reset, then on your phone ( or whatever you connect yo you chromcast with) change the date back to before the problem. I used the 9th March.

Set up the chromecast on goggle home.

Chromecast will then connect and update.

Wait for chromecast to then update and then you can use as normal.

Don't forget to cahenge date again on your phone

For those who have factory reset: Change the date of the phone/device you are casting from to March 6th and you will be able to connect to Chrome cast. After connecting you will receive the update and it will work.

Ya esta la solución a los chromecast reiniciados?

[Chilapo64]

Solucionado. La nueva actualización desconfiguró el audio. Lo resolví configurando el audio en la tv. Todo sin problemas. 

[Tarteaga]

El mío sí,  desde ayer. Y lo había reiniciado varias veces 😐

[Jeaguilera]

Cuando se solucionara el problema con las personas que reiniciaron el chromecast de fábrica y aún no podemos configurarlo 

[Tarteaga]

El mío ya funciona desde ayer, y lo había reiniciado varias veces. Creo que progresivamente funcionarán todos. Suerte!!!

Hello,
I just updated the Google Home app to the newest version that was suggested today and I still can't connect?

[Underdog101]

I'm having the same issue... read through all the help screens etc but the Google Home app does not see this Chromecast or an older Nexus TV devices on the same Wifi network etc.

[Alejandro71]

hola, tengo dos dispositivos, dejaron de funcionar ayer y los restablecí a fábrica....fue el procedimiento que vi para resolver fallas de conexión...desde ya muchas gracias.

[Rickyc560515]

Estoy en tu misma situación, veremos que habrá que hacer para los dispositivos reseteados.

[J_Clark]

Hay otro post a bajo en ingles, pero te lo pongo igualmente.
Como workaround temporal puedes cambiar la fecha de tu telefono a antes del 9 de marzo (el 8 por ejemplo) y luego configurar el Chromecast.
Lo hice y funciono: El chromecast ya esta de nuevo conectado a la wifi, pero obviamente sigue sin poderse hacer cast de nada.

[Alejandro71]

Muchas gracias por tu tiempo y ayuda! Lo hare y te comento! 

[ccouto]

no perca su tiempo, hay que esperar google comprar otro certificado de seguridad

[caeds3401]

[Atbinnb]

[Fco1]

[CM71]

[ccouto]

[FOO_SAYS]

[Amyandnoah1]

[Jô]

Como você fez?  O meu não está funcionando. 

[Dukecito]

It works!!! Now i've restored my Chromecast 2 main screen with time and with Wi-Fi connection at least, so now my device is ready again to wait the next Google Update for my Chromecast 2 to fix the outdated certificate of firmware.

Yj_Clark. You are the boss!!! Thanks for this incredible helpp!!!!

2nd generation Chromecast model NC2-6A5: I reset the device to factory default, following the series of suggested fixes issued by Google. As others have mentioned, I could no longer connect to the device to set it up. Following the advice noted in this thread, I set the phone's date to March 6. I was able to connect to the Chromecast and get it back on WiFi, so others that mentioned a certificate expiry issue may be right. I still cannot connect to the device to stream anything, but with fingers crossed , Google will be able to push the fix to my device. Thanks for the good advice!

[Sandra181]

Gracias, voy a probar

[Marianamulata32]
