 i did the same a factory reset and i face error, we couldn't authenticate your chrome device, could you suggest if you come across this problem 

[dorotheo_jara]

Não estou conseguindo fazer a instalação do meu Chromecast minas já está instalado e do nada parou e agora eu não consigo instalar já fiz a restauração de fábrica e agora não consigo entrar e fazer qualquer tipo instalação

[gabrielagramos]

Oie! O Chromecast de geral tá assim. Deu algum problema de certificação digital no Google. Eles pedem pra não resetar. Resetei e agora tô esperando uma solução. Mas fica tranquilo porque não é só o seu. Simplesmente quase todos os chromes do mundo pararam. 

[Patr1]

Hola gente. Yo fui de las que hizo reinicio de fábrica pensando que era problema de mi equipo. Tomé la sugerencia de aquí del foro, cambié la fecha de mi teléfono al 7/03 y pude volver a conectarlo, pero sigo sin poder enviar contenido. La información que circula es que  Google solucionó el problema, pero yo estoy como el primer día. ¿Alguien más en mi situación?

[Eduardo68]

Hola, hice lo mismo que tu y tambien estoy esperando a que se actualice, saludos

[Eduardo68]

Bueno, acabo de prender y apagar y se actualizo y quedo andando, por fin. Saludos y suerte a todos,

[Eduardo68]

Por las dudas cada cierto tiempo hagan eso, de apagarlo y prenderlo a ver si tienen suerte.

[Marley4]

Hola yo también hice lo del cambio de hora y a tardado pero al final se actualizo y reinicio Chromecast y me vuelve a funcionar  

[Agus_MG]

Hola. Hice lo mismo, reseteo de fábrica cuando hubo el fallo y luego lo configuré cambiando la fecha del móvil. Esta mañana lo he reiniciado y ha saltado la actualización pero se quedó al 0% y al final indicó problema de red. No ha vuelto a saltar. El Chromecast tiene conexión a internet porque aparecen los fondos de las fotos de Google y es visible desde los equipos, pero no permite conectar por certificado. Ahora ya dudo que se pueda actualizar.

[edulongo59]

Lo mismo que ustedes, siempre que un dispositivo falla aconsejan restablecer, Google se avivó Bien tarde y dijo que no lo reiniciemos cuando la mayoría lo izo, y ahora qué? Ni ellos lo saben,que esperemos cuanto??

I can't believe that Google hasn't pinned this information to the top of this page, for all the thousands of folks like yourself who have done a factory reset.

In any case, it's an easy fix. Just do this:

[Rodri1]

Yo estoy igual, lo voy a usar de pisa papeles

[Gonzo77]

Buenas tardes. Hice lo que mencionaste. Puse una fecha anterior al 9 de marzo y me empezó a configurar el Chromecast. Una vez hecho esto volví a actualizar la fecha del celular y pude conectarme y transmitir nuevamente 😃😃

[Marek2567]
