Perfetto ...cambiate la data manualmente  impostate 1 marzo e via tutto funziona 

[Stevesmthg]

What if we factory reset the device? I did so thinking it would fix the issue. The statements on this site were not posted yet. Will my device still work when a fix rolls out?

Façam a correção o mais rápido possível, já vamos entra pra uma semana com esse problema e nada… tenho certeza que todos que compraram os chromecast é pq necessitam e vcs ficam enrolando pra fazer uma atualização. Acredito que se vcs quiserem conseguem fazer isso com mais eficiência e rapidez possível… aí fica vários usuários do Chrome com cara de palhaço esperando a boa vontade da Google.

I have 4 Chromecast Audio devices & 1 Chromecast Mini.

The Audio devices all stopped working and as they were in a group with the Mini I originally thought it was an issue with my router or the mesh-repeaters I have.

I reset the router and the mesh devices but still no joy.

I then reset all of the Chromecasts, including the mini.

I then deleted the group they were all in and started by setting up the Mini again. No problem there, connects fine and plays audio.

Next I tried one of the Audio units. Home found it and asked if I wanted to set it up. I clicked yes, but after a while it just said "Could not communicate with your Chromecast Audio."

I get this with all 4 of them. I also have two full Chromecasts that haven't been used for a while and I get the same result with those too.

I have tried everything I can think of, including connecting the WiFi to the Chromecast first and then opening Home to set them up. Nothing is working.

Mobile (cellular) data is off, WiFi calling is off.

Is there anything I can do? Or should I just bite the bullet and go talk to 'Alexa'?

[Abertawe]

Exact same. Looks like a global issue.

[Emma6T]

I wouldn't mind so much if you could still get the audio only Chromecast, I bought the second two when they were discontinued. I've had them quite a while and don't expect anything to last forever, but... 

[Novyz]

There is a temporary fix: https://www.googlenestcommunity.com/t5/Home-Automation/Fix-Chromecast-authentication-issues-Fix-cast...

[Emma6T]

I've tried that and unfortunately I still get the same "Could not communicate with your Chromecast Audio." 🙁

[Emma6T]

I tried that but unfortunately it didn't work for me. 😕

[Anthony58]

It's a Google issue not an issue with you. Someone forgot to update the certificates for older gen 2 Chromecasts and Chromecast audio. You should have gotten an email from Google like I got after I spent 3 hours troubleshooting. My regular Chromecast works now but the Chromecast audio is still out. It's either because I did a factory reset and removed it from my home group or they're getting to the audios last. This is why you're mini was not affected. Only the older equipment

[Emma6T]

Yeah, it's just a shame I've reset all 4 of my Audio's. At least I still have the Mini to use until (if) it gets sorted out. It was nice to be able to wander around the house and have the sound synced in every room... 

[Alexandra45]

When is it going to be fixed?

[JuliK]

Hola equipo de Google,

Yo también fui víctima de la falla de Chromecast que ocurrió este fin de semana.

Mi equipo falló, no se solucionaba y opté por resetearlo de fábrica (como en otras ocasiones).

El aviso de Google estuvo fuera de timing. Comunicaron que no debía resetearse cuando ya miles de usuarios lo habían (habíamos) realizado 

Por favor, ¿podrían decirme cuál es la solución en este caso? ¿Cómo van a resolver este problema?

La falla fue de Google y no deberían responsabilizar a los usuarios.

Quedo atenta a su respuesta,

[GISELLE_REYES17]

Yo también lo resetee y no puedo solucionarlo

[iascierto]

Estoy igual y ya van 3 días. Alguna novedad???

[JohanaInfesta]

Me paso exactamente lo mismo y todavía no hay solución 

[kel72]

Por lo que leí, dijeron que van a sacar una actualización de firmware (lo que eso sea ni idea jaja) automática para todos.

los que los reseteamos también, pero supuestamente va a demorar un poco más en llegar, ya que habría que hacer un paso extra.

En mi caso luego de resetearlo lo que hice fue cambiar la fecha de mi teléfono al 8 de marzo, que fue el último día que funcionó, eso me sirvió para poder volver a conectarlo, pero ojo, aún no se puede transmitir, solo está conectado y me sale el mismo error de antes de resetearlo.

Saludos

[VRog]

Me ha servido tu consejo de cambiar la fecha a una anterior y así poder configurar mi Chromecast. Y si sigue sin proyectar pantalla pero al menos ya puedo esperar la actualización, si es que hay.

Gracias 

[Marta09]

Uau, no sabía q era un problema global y me estaba rayando demasiado. En automático dejó de funcionar el domingo por la tarde. Hay q esperar la actualización automática entiendo, no?

[kel72]

Si, solo queda esperar que Google lo solucione, esperemos que sea pronto

[CookieHappyCat]

See my post, Fix Chromecast Issue, it works properly @CookieHappyCat
