Same problem here. Can't authenticate chromecast. Neither the chromecast for the tv or the chromecast audio. I reset all chromecasts multiple times and even reset my wifi and google home account. Still no luck.

[Djb200]

Telling people to not reset devices to factory settings came far too late for the majority of us!

You sat by for almost a day before issuing any statement. What do you people do all at???

And still no fix for anyone.

[Joe36]

But where you can find it. I did reset already, its not working for 2days now

[skynetesq]

Please provide another update

[Bryan99]

After a day of issue in setup that needs to be authenticated, some how it manage to overcome that but now it is unable to connect to a wifi using an iphone to setup. 

[Brendan2002]

I also get a unable to authenticate Chromecast message

[papur104]

Cuando el Chromecast dejó de funcionar anoche, hice lo que el centro de ayuda de Google recomendaba, entre otras cosas reiniciarlo. Ahora leo en el hilo que Google comenta que si se reinicia a lo mejor no se soluciona... Menuda gracia.

[Paolo_1960]

After years of work, this evening suddenly chromecast doesn't work anymore.Trying to reconfigure with app "Home", it recognize it, but  it is not able to autenticate it, so reconfiguration does't complete. On Tv video, is showed code L7Q8 . Tried to switch choff/on and reconfigure many time without esit.

Is it a Trump gift ?

[Feeley67]

Same thing happened to me!?!? Sent a mssg to Google, so we shall see. I will ,as well ,blame it on Trump!?

Error de conexión

No se pudo establecer conexión con Chromecast. En la configuración de privacidad del teléfono, asegúrate de que el acceso a la red local esté habilitado para la app de Home. Luego, vuelve a intentarlo.

[dracarolrocha]

Chromecast shows images but wont be found by Google home nor devices.

Wi-Fi is working; this Chromecast used to Work, although had a hard time previously trying to

install it. 

It shows inactive in Google Home. It format cast anything.

Pls help

[kcruzgonzalez]

Hi dracarolrocha,

Thanks for posting in the community. I'm sorry you're having trouble casting to your Chromecast. I understand how frustrating that can be, and I'm here to help.

To help us troubleshoot effectively, could you please provide the following information?

• What Chromecast model do you have?

• What operating system is your phone or tablet running (Android, iOS, etc.)?

• What version of the Google Home app are you using?

• When you say it "shows images," what exactly do you see on your TV screen? (e.g., Chromecast backdrop, error message)

• Is the Chromecast plugged directly into a wall outlet, or is it powered by the TV's USB port?

• How far is the Chromecast from your Wi-Fi router?

• Are you using the same Google account in the Google Home app that was used to set up the Chromecast?

I look forward to your response so we can get this resolved.

Regards,

Kevin

help?

I am having the same issue.  Its the 2nd gen chromecast that I've had since 2017.  It has been plugged into my tv via hdmi and gets it's power from the usb A slot on the TV.  It connects to the wifi and shows the rotating pictures, weather info and time at the bottom right on my TV.  The issue is I cannot cast from my android phone or windows computer that I've been using flawlessly to connect with for years.  For instance, when I attempt to cast from youtube an error pops up and says "Den TV (name I gave it) couldn't be verified. This could be caused by outdated firmware."  I checked the firmware that Google Home is saying that it has for the chromecast as being up to date according to Google's firmware page (vers: 1.56.275994).  Google Home says that the chromecast is offline.

[Jessed89]

I'm having the same  exact issue. I think the may have discontinued support for the gen 2 chromecast. Gen 1 support was officially discounted. Mines was working fine then 30 mins later it stopped.

[Pipsqueak]

I am also having the same issue with almost the same system setup. I have restarted everything and uninstalled/reinstalled chrome but still get the same error. I wish there had been a response with something helpful to offer.

[strugglingtobe]

The same thing is happening with me. Chromecast 2nd gen, IOS, just updated google home, It was showing images from chromecast being plugged in, until I reset the system.  I have turn off my phone, the wifi.  TV is plugged into wall.  I am 5-10 feet away from router and TV.  I am using the same account I set it up with a few years ago.  I have checked my app to make sure it shows location network and bluetooth are enabled in the app.  I continued to get the TV may be set up, but could not communicate with it from your iphone.  

[theochromecast2]

same thing. Suddenly was unable to connect from apps or Home.
After factory reset not able to set it up again

Same problem here, since today, with 2 Chromecast 2nd Gen (that worked flawlessly for years, In 2 different homes) until yesterday. Fed by usb-power-adapters, plugged in in hdmi-Port of both tv's, still showing default screen saver nature pictures, weather and date/time. On setup with Home-app "device can not be authenticated" and Home-app demands location-rights which it gets but keeps asking for. Netither my chromebooks nor chrome browsers nor apps offer display on chromecasts any more. Did Google drop support on 2nd Gen Chromecasts or just screwed up an update of Chromecast or of the Home-app? Very sudden, weird and unpleasant experience. 

[u2hertz]

I truly hope they resolve the issue. I don't need some over bloated device trying to do too much. I just want to be able to cast from YouTube, Prime and my laptop. It worked so well for so long.

¿Que pasa con Chromecast? No me deja transmitir hacia la tv, intenté configurar y para mi sorpresa esta fallando la configuración, reinicié de fabrica y desde la aplicación home, lo detecta, sin embargo arroja error al querer conectarse. Cabe mencionar que lo he intentado de diferentes formas, con diferentes celulares, reinciando wifi, eliminando app y así sucesivamente. ¿Alguien sabe a qué puede deberse? Veo que es un problema masivo.

@Chromecast @falla

[lolide]

Hola,  a mí hoy me sucedió lo mismo. Podrías indicarme cómo lo solucionaste si es que conseguiste hacerlo, por favor? Gracias!

[FelipeG1]

Lo mismo hoy, en dos dispositivos distintos, en dos ciudades distintas el mismo día!!

[Priscila1]

O meu tbm tá com mesmo problema. 

[Davesiant1]

The trouble shooter literally told me to factory reset! Am I now stuck?

[Tota]

I need help to set up the device to my TV the Chromecast is not connected to my TV

[punanidigger]

bruhhhhhh still not working!!

[Paameelaa22]

Me parece una burla que suceda esto sin algún tipo de aviso . Todos mis aparatos dejaron de funcionar, cuando los adquirí jamás me dijeron que vencerian. Ahora de un momento a otro me quedé sin conección y siento que nos toman el pelo que esas soluciones inservibles que nos brindan . Eh probado todas ninguna funciono . Acaso como consumidores del producto no podemos hacer nada ?

[Rickyc560515]

Algo parecido me está sucediendo. Ningún dispositivo se pueden conectar con mis 2 chromcast. Los resetée y ahora no puedo configutrarlos.

bonjour je n'arrive à me connecter à mon chromecast

[Caro64]

Moi non plus depuis hier soir. Je viens de lire dans les médias qu’il y avait un bug mondial.  J’ai contacté l’assistance qui me dit la même chose : , qu’il y a un problème avec les appareils chromecat mais ne me disait pas comment les résoudre. Et vous ? Toujours pas de connections ?

[BDR]

Chromecast is connected to my router, but it won’t work from my iPad. When I go to Google Home app, the screen displays “Get the app” and I cannot get rid of it. I’m already in the Home app, so why is it telling me to get the app? I have no idea which generation of Chromecast I have. How do you tell?

[alvarenga7udb]

If you did factory reset, please see this article, it served me well, as I also did a factory reset. This only works to get the google chromecast show the google stock wallpapers, but we still have to wait for the issue to be solved.

O meu chromecast de 2° geração não está sendo autentificado pelo aplicativo Google Home. Aparece uma mensagem informando que não foi possível autentificar, e que eu deveria checar o suporte. Reiniciei o dispositivo diversas vezes, mas o problema persiste.

[Priscila1]

O meu tbm tá com mesmo problema. 

[Sandra_Gdu]

Mismo problema 😞
