Down again, only sound 😱🤯

[SuzSmith]

Still doesn't work after downloading the latest Google Home app. Tried restarting my phone and reconnecting the chromecast but still doesn't work. I also tried to change my phone date back to 7 March 2025 but it still doesn't work.

[Caewils]

Is it down again? Mines not connecting again?

[JoyK]

Thanks!

[santosha]

It still doesn't work. While setting it up, it doesn't update at all and after sometime it says network error. Its been two months and google has no clue how to resolve this. Its a shame on the company.

[Tash8]

Thank you so much for the updates! This has been so helpful! My Chromecast is finally back up and working. 

[Bamfordster]

Hi, I just updated to Home 3.30.1.16 and am happy to say it is now working.

Thanks!

[staricon]

[UwUdictator19]

Hi,

Could you share the Google Home update that will allow me to update my Chromecast? My email is #

Thanks.

Voltou a funcionar meu chromecast 2ª geração após atualizar o Google Home para a versão 3.30.1.6 para android. 

[BoLL]

Sorry, still doesn't work after updating to 3.30.106 for iOS. After connecting to my wifi I get the message "couldn't communicate with the unit on your iPhone..."

[pbanders]

See my post about 10 minutes after yours. Factory reset fixes the issue, at least for me. 

[aza1099]

Did you do a factory reset 

[pbanders]

FYI, I just resurrected a Chromecast Audio that was destined for recycling. It had never been factory reset. I have the latest 3.30.1.6 (Android) Home. Connected to Home during setup just fine, but wouldn't connect to my Nest WiFi mesh network at the end of setup. Tried multiple times, reboots, etc., didn't work. Found an old post with the solution - do a factory reset! Did a reset, re-ran  setup and was connected to my wifi with no problems at the end of setup. Hope that helps with anyone experiencing the same issue. 

[eveliving]

the google home upgrade that was rolled out today/yesterday did the trick. i could reconnect my device phewx

[Pip_pill]

Chromecast Audio - Have Home 3.30.1.6 on two phones,  2 of three Audio devices are Firmware version 1.56.467166,  the 3rd goes through the process of connecting and will not connect to WIFI but shows on the wifi router interface it will not show on the home app. The other 2 will show in the home app but state "wifi not connected" when interrogating the devices. Plexamp that is used to stream to the devices no Audio devices appear in cast, Media monkey has every cast re connect that has been set up to connect to 10 instances plus 4 Non existent groups. Devices do not show up in Groups that they have been set up in

Very concerned that this has been passed to customer support  who I have never had any luck in getting an answer from.

[pbanders]

Take a look at my post below yours.

Hi there - I'm still unable to update this despite having the latest version of the app, and when I tried to contact support as directed the link to send a message didn't work! Please can you advise what I can do? Thanks 

[Taradon]

Only seeing updates about how it's fixed but yesterday customer service told me it was known that android users were still having problems and to keep waiting.

Is this correct? If so, why is not mentioned in the update today, seems important for people to know

[vtfreerider]

Yeeeaaahhhh....still not working. Did the factory reset a week ago and, in spite of your assurances that it's all well and good now....it isn't. Unable to setup and see the lovely numbers on the screen. This blows. First it's my pixel's battery life sucks because of your update. Now this. 

[Rafadreans]

Deu tudo certo, atualizei o iphone com a nova versao do ios, reinstalei o app google home e configurei nova casa e adicionei o chromecast, ele configurou e baixou a atualização, td funcionando!!!

The update changed nothing for me.

I had reset the Chromecast before y'all notified the world about the bug. 

Today I was finally able to update the Google Home app to the new version that's supposed to fix the issue. This did nothing for me and the issue still manifests.

Right after updating it seemed hopeful.

Sadly, though, nothing.

A second attempt...

I reset the Chromecast again, I rebooted my phone (Fairphone5 w Android14). I ensured that my wifi was still only 2.4Ghz and that my Bluetooth was on. Nothing helps...

I still get, after lots of attempts and loading and "connecting", the "could not connect" and the "could not communicate".

Square one.

I had a support call with Google. With all the troubleshooting I myself had done, I completely overlooked the possibility of fully uninstalling the Home app and reinstalling. This helped and I was once again able to connect my Chromecast Audio and cast music towards my speakers!

[trob1]

i tried this and it still didn't work. 

[Betoraf]

Hola buenas noches gente de Google, un comunicado con explicaciones técnicas no es una solución, yo lo solucione a mi manera, pero todavía hay gente que espera una solución automática y creo que les corresponde a ustedes contactarse, todavía hay gente que no sabe cómo actualizar su dispositivo, digo su dispositivo porque uno lo compra y tenemos que seguir dependiendo 

[alho57]

Hi - How can I check if I have version 3.30.106 for iOS?  I have an iPhone 7 (version iOS 15.8.3)

Will I be able to set up my chromecast now?

Thanks

[Danny2490]

Ok help me please 

[Zeyre]

Thank you for following up and actually solving the problems even for those who did the factory reset.  Your diligence and honesty is appreciated. Thank you.

[glendanzig]

Updated Google Home, setup went well, but can't send content to the TV!!

[RamaIndrawan]

All fixed now with latest Home app on Android Samsung. I was 1 of the ones who performed fatory reset

[rupeshshakela]

Download

[Buurman]

Took some hours and "bad language" but everything is working fine. 

Even the Homeapp behaves much better with the 5 Nest mini's

[RS31]

My Chromescast is working now but casting is poor. Quality is very low and keeps dropping connection even though wi-fi is working fine

[JoyK]

It's working now after the 3.30.16 update. Many Thanks!

[AJ42]

J'avais réinitialisé mon Chromecast et en changeant la date de mon téléphone avant le 9 mars (astuce donnée sur la communauté ) mon chromecast remarche avec Google home. Dois faire cette mise a jour que vous proposez ou bien laissez comme tel. Merci de me répondre
