I have been a user of a Chromecast device for years. Today, I was unable to cast as usual. I factory reset the device and have been trying to add the Chromecast to Google Home. 

After getting through most of setup, includig entering the code that appears on the tv, I get error msg stating that "something went wrong: Living Room TV may be set up, but we could not communicate with it from your iPhone. Make sure that you have enabled local network access in your iPhone’s privacy settings. Then try again."

I have followed all the troubleshooting steps. Local network acces is enabled.  AP Isolation is not enabled on my router. I tried a second iphone and had the same error. What else can I do to make this work?

[HeidrunM]

I have the same problem. Tried the same steps. No solution yet. Ps tried from an android device as well

[D123]

Me too. Worked for years with no problem. Any updates? Ive been waiting for a call back for 45 min

[Lektoran]

I have same problem

[Heron21]

Looking at the replies here, it seems like many people around the world are having this problem today. Like others, I initially received a message when attempting to case that the chromecast was not a trusted device and may require a firmware update. That was why I tried the factory reset.

[MattQ]

Same.  I was literally using my Chromecast Audio this morning to stream Spotify.

I know they ended the product in 2019 and said they'd keep releasing updates until September 2025 but it looks like a TLS security certificate on the device finally expired and they didn't update it to a new one.  Now we all throw them away because Google won't allow us to transition it to the OpenSource community and maintain it ourselves. What a waste.

Hoy 9 de Marzo 2025 dejo de transmitir mi google Chromecast y ayer estuve sin problema usándolo ya hice de todo vi tutoriales y todo pero no logró conectarse a alguien más le sucedió?

[felixjarbelo]

A mi me ha petado también hoy sin explicación. He reiniciado la configuració de la tele, h reiniciado el Chromecast, he actualizado la app Google Home y nada de nada. Al principio de todo me decía que era un problema con el firewall de mi dispositivo pero ahora directamente ni conecta habiendo hecho múltiples reinicios de todo

[AdrianaHoving]

Estava funcionando perfeitamente até uma hora atrás, espelhando a série para a TV sem problema algum e então simplesmente desconectou e eu não consegui reconectar. Tentei:

- Desconectar o aparelho Chromecast da tomada e da TV

- Desconectar o aparelho do Wi-Fi 

- Deixar desligado de tudo por alguns minutos

- Espelhar de outros serviços de streaming

E o problema permanece. Até onde parece, continua normal, as fotos continuam mudando na TV, horário e temperatura normais, mas o número PIN e o nome do meu Wi-fi sumiram. Quanto tentei conectar o YouTube, deu erro e apareceu uma tela falando sobre o firmware não ser confiável. Gostaria de pelo menos saber o que está acontecendo já que pelo visto não sou a única passando por esta situação com o aparelho.

[LuiggiVop]

O meu aconteceu a mesma coisa, mesmas mensagens! Fui reiniciar ele pra configuração de fábrica e ele não passa da parte de conectar com Wi-Fi… já reiniciei o wi fi, está no mesmo Wi-Fi ele parou do nada 

[Pmoneygroup]

My chrome cast in my living room and my bedroom stop working suddenly today being 9/3/2025, it was working this morning but stop all of a suddenly…I thought it got spoilt but after seeing people complaining it means the fault is coming from the quarters or web don’t really knows 😭💔 please fix this I don’t have smart tv that’s the only source of me watching Netflix and YouTube 

[Cass3]

Hey my Chromecast is not working too have you find a solution?

[Lefkatas]

I tried everything reset delete the device and add it again but nothing happened. Also I use the AI to know what is the mistake but I don't have any answer. It happened to me about 10 minutes ago suddenly with no reason

[Florzita]

Hola! Me pasó lo mismo, estaba funcionando lo más bien y de la nada dejo de funcionar, intenté hacer todo pero no puede volver a conectarlo

[Gonfa91]

El chromecast dejo de transmitir y no lo puedo volver a configurar. Me dice que no lo puedo auntenticar. Alguien sabe el motivo?

[morf]

Same mine...el motivo? Google is not able to do updates without destroying something else..

[yanelp]

Me pasa lo mismo. Hoy andaba perfecto. Y ahora error de autenticación.

[DiegoHernan]

No puedo configurar el chromecast, me muestra jn mensaje que dice, no se puede autenticar el chromecast, lo reinicie de fabrica, y tampoco me deja, hay buena conexión a Internet, la app home esta actualizada, cuando quise trasmitir antes de reiniciarlo, me decía que posiblemente wsta desactualizada la versión de firmeware. Probé de varias manera y no se puede.

[Hds]

Lo mismo

[Barbara84]

Same here in Argentina. Es el mismo problema a nivel mundial. No funciona. Por esonqueremos una respuesta.. solucion o dejara de funcionar?? Pero al menos una respuesta de parte de google

[Navrig]

I have a Chromecast Audio I have been using for years.  It has always been setup in the same place.

We haven't used it as much as we used to but this afternoon I decided I wanted to stream some music.  Although Spotify offered it as a device for casting it could not connect (this was from my phone).  I tried several times.  Spotify on my Chromebook couldn't see the Chromecast Audio.

So I reset the Chromecast Audio - pressing the reset button so the LED cycled white/amber (flashing)/white (steady).

Then I tried to add it to Home using the app on my phone.  I get the error shown in the attached sccreenshot.

I have tried 3 times to do this and get the same message each time.  The link offered doesn't seem to suggest any solution.

[Bob_bob]

Have the same problem, yet where is the support on this one?

[Kurtmieville]

Same here. It seems they shut down the older Chromecasts around 6 pm CET. Got the same problem all of a sudden on one second generation Chromecast and three Chromecasts audio. Our whole video/audio set up is gone.

[Niko2]

Same issue here, reinstalling Home app, rebooting Chromecast or internet is not helping. Please find a fix

[joelios]

It happened to me today with my Chromecast 2nd gen. I hope it's not permanent 

[Navrig]

Thanks for the quick replies.  Glad it's not just me but I hope they fix it otherwise I have an amp and ceiling mounted speakers which will be redundant.

[Nmr916]

Same for me, I have 3 chromecast audios that have stopped working completely, can't authenticate to set up after a reset, no, changing networks, rebooting router, clearing cache on home app, did not work

[trob1]

Hi, I've been using my chromecast for years with little issue. Tonight it suddenly disappeared from my apps (like Netflix, Chrome browser etc.) and was listed as unavailable in Google Home. I've tried every single troubleshooting method several times:

- rebooting wifi (waiting 1 minute or longer)

- rebooting chromecast (waiting 1 min or longer)

- force stopping, then uninstalling / reinstalling google home

- reset chromecast to factory settings

When I reset it to factory settings, google home will find the device and attempt to connect, however the number it is trying to connect to is slightly different. Let's say it asks if I want to connect to Chromecast1234, which is what shows on my TV, it will then attempt to connect to Chromecast1234.b, (including the comma there at the end). Then it will say that it cannot communicate with that number. Going through my wifi and trying to connect there also does nothing: it says it connects with no wifi.

I have literally tried everything in all the forums. I believe it's the 2nd Gen chromecast only because the reset button is a tiny button sitting flush with the device on the edge of the device, not a big button on the back or anything. 

Can anyone help?

[Dyjaco]

I have good the same

[Emijo]

Same for me. Hope google acknowledge this issue soon

[Jeovanevs]

Same here.

[Whatajerk]

I've tried the exact same methods and got the same result. Seems to either be a firmware issue or they're phasing out the gen 2 without prior warning which I doubt. Hopefully it'll be fixed and they're aware if it. We all need to just report it so they can investigate. 

[Elber]

Same here

[Rgallaghersf]

This is 99% my exact same experience tonight. Hope Google will provide an update soon.

[Francis36]

Exactly the same for my gen 2 and my CC audio. Let's wait... 

[ausclassics]

2 of mine did the same too and every trouble hoot method failed!  Not happy!   On hold waiting to talk to support now.

[Sandie1]

Same for me!

[Landotter]

Casting from VLC, Pocket Casts, or SomaFM worked great. But Google Home stopped connecting so no volume control. I reset the device to add it again and I'm getting an error: We couldn't authenticate your Chromecast Audio. 

Is this device no longer supported? 

[Julie_K]

I get the same issue with my chromecast mid cast, an i get the same error after resetting and trying to reconnect
