Same here yesterday my chromecast was working, and I have deleted installation and reinstall without any success

[Mavura]

Same here

[JoL1]

Same for me. Working yesterday morning and not now.  I've rebooted and now it doesn't even let me install it again.  

[BartN]

Same here, I have been using 4 chromecast audio devices for years, and this morning suddenly nothing worked anymore. What happened?

[BadFlash]

An intermediary SSL Certificate expired on you CC device.  Google needs to either renew that certificate and resign all CC SSL certificates with the new intermediary SSL Certificate or come up with another solution that would be quicker to deploy on those millions of devices.

[queiroztfm]

That's my main frustration the network audio streaming no working. 

[Gabrielet]

Anche a me da Parma non va più e non si collega.. Mi rincuora non essere l unico

[Hacsennin]

Same issue,

One decide works fine the other one doesn't.. so gotta wait for Google to fix it?

[Zimzom]

I have exactly the same problem I been trying everything!! Happy days 

[ErikLucidor]

Worked fine yesterday, stopped working tonight. Authenticate problem... Please solve this quick Google. From Sweden 

[Zimzom]

Samma problem här  försökt allt. Tänker att jag kanske går o köper en nyare version  dom funkar tydligen..

[Curre]

Finns bara Google chromecast för 1399 kr på elgiganten 

[Liliboop]

J'ai le même problème également.

Tout marchait bien il y a 2 jours et malgré un réinitialisation, il n'arrive pas à authentifier mon appareil 

[TykeGuy]

What’s really frustrating is the lack of any proper acknowledgement or holding message from Google. Seems to show contempt for a millions of loyal Chromecast and Google Home users. Been considering a move to Amazon infrastructure for a while, this may force my hand.

[Claudietta]

Io ho anche un Fire Stick Amazon e posso assicurare che è una bomba! Infatti sto pensando di dismettere il Chromecast e passare ad un altro Fire Stick Amazon 

[Caa81]

So glad I found this community, ive been resetting my Chrome chromecast, phone and WiFi for the last 30 mins wondering what is going on! Clearly it's a google issue 🙄 

[djg3inomaha]

I feel your pain!  I wanted over 3 hours trying every fix I could think of to get my 14 (yes, 14!) devices working.

Wish I had come here first to learn it was nothing I could fix.

Woulda saved a lot of time and frustration.

All I can say is that they better get it fixed quick.

This is soooo not good.

[Caa81]

Haha, I tried earlier today and nothing but didn't worry too much about it until just now. Glad it was on 30 or so minutes of getting angry at it 

[Curre]

Have done the same, nothing is working...!!!

[Helloworldgoogl]

[Curre]

Same here!

[Turkestan]

En la misma situación de todos. Pero que hacemos? Nadie da la cara. Demasiado tiempo de mi tiempo probando de todo. Muy frustrante. Hasta ahora cero solución.

[Mrtax2005]

If you did factory reset, please see this article, it served me well, as I also did a factory reset.

How will you provide these instruction? By email to my linked account?

[RonComstock]

Where do I go to see the problem fix when there is one. I'm paying by the year for a streaming service I can only see through Chromecast.

[Geogandoro]

Desde ayer en la noche, el Chromecast no me dejaba enviar nada, ni desde pc, ni desde móvil, lo he reiniciado de fabrica y ahora no es capaz " de autenticar el Chromecast" ya que no me salta la opción para aceptar o no el código que aparece en la pantalla, veo que es un problema global pero, ¿Se sabe algo?

[Wannportela]

Tenho o mesmo problema , parece ser generalizado 

[M4koka]

Tengo el mismo problema desde ayer!!!

[carole94]

same probleme in france since yesterday

[Mauricio01]

Tengo el mismo problema desde ayer, si te dan alguna solución podrías compartirla?

[Gustavoden]

Mismo problema. Se agradece compartir la solución si la encuentran.

[Faso1112]

Bumping

Mismo problema desde Colombia.

Espero puedan dar solución pronto.

[Geogandoro]

Todavía no hay solución creo

[AlejandroTobar]
