Est ce que quelqu’un peut expliquer comment changer la date sur son iPhone SVP ???

[Afafaiel]

Deveria processar pela perda financeira. Eu tô puto da vida com isso TB. 

[Anonymous]

Another member suggested changing the date on your device.  I changed mine to the 4th March.  I'm now up and running and watching Loki.  Can't find the original message but it worked.

[billgeddes]

Performed factory reset before receiving notice of outage from Google, so still getting "Could not communicate with your Chromecast Audio" error.

[MattiasL]

HOW DO I REBOOT IT???

[Teodosio]

Purtroppo avevo già ripristinato la chromecast, attendo quindi con ansia la risoluzione del problema. Grazie

[Hierocles]

segui le istruzioni che ha postato Condor, va a posto. 

[The_quick]

Stessa cosa avevo fatto io e ora non la app Home rileva il chromecast ma non riesce più ad installarlo...

[Mikazuki124]

Olá, meu dispositivo não voltou mesmo, instalando novamente o aplicativo.

[sbharvey374]

Have you done a factory reset?  If you haven't just leave you device powered on, on your Wireless router.   If you have reset your device do the following:

[Leozinho92]

Quem redefiniu, é só mudar a data do celular pra dia 8 março deve conseguir parear novamente o chromecast , o meu voltou ao normal já 

[Snackpac12123]

Last night I plugged them all in so they would be on my wifi, for any updates

And this morning, 

All of mine are working now, even though I factory reset them before I knew they didn't want us to. 

[Taschr33]

It works fine as of March 14th.

I hadn't done a factory reset, thank goodness, and my chromecast 2nd gen suddenly appeared on the Google home app 

[Sarce]

Ainda estou com problemas! Já reiniciei e nada! Estou aguardando a solução.

[GitarrLasse]

You saved my life!

[Aynur1976]

Het is echt belachelijk voor woorden, dit is echt niet acceptabel.Waarom werden er geen mails verzonden.had mij hoop uren kunnen verhelpen!! Mijne werkt nog steeds niet omdat ik later zag dat er probleem was , ik had t apparaat gereset!! 

[Andre123]

Niet mauwen.

Gelukkig heeft GOOGLE het opgelost. 

[The_quick]

I had reset the chromecast before these instructions. I am trying to set up the chromecast again but without success. This is the message I receive: "unable to authenticate the chromecast device"...

The work around that worked for me is to reset your phones' date to earlier than 8 March 2025. Run Google Home and add your device. You should follow all prompts. If you are in an area that Google has rolled out the update, you should see an update progress bar on your TV and the Chromecast will probably power reset twice. Don't forget to reset your phones' date. Open Google Home, see if your device is listed.  Open you Streaming App on your phone and test casting. Goodluck.

[Jyr]

Ok. All running😁

[JGalore]

We’re back in business, thanks Google! 

[Webooide]

Yayyy finally! 

[Andre123]

2 chrome cast audio work and have the xxx166 version. 1 i reset before, using setting the date back on phone I could connect it. 

Thaaaaaaaaank youuuuuuu GOOGLE.

[TamCaviar]

[Mary25]

Bonjour 

maintenant quand j’essaie de connecter mon chromecast ça deconnecte mon wifi 

je suis obligé de redémarrer mon routeur pour avoir du wifi 

mais de nouveau quand j’essaie de connecter mon chromecast plus de wifi 

quand je n’essaye pas 

ça fonctionne normalement 

donc pour moi votre solution ne fonctionne pas 

[Kels2]

It's working, yey!!! Thank you.

[CM71]

Sí anda , graciass equipoooo google!!!!

[Pete90]

Personalmente da me Torino Italia è stato sufficiente riavviare il Chromecast ed è giunto l'aggiornamento,che prima automaticamente si e scaricato ed a seguire sè installato! Ed ora funziona come prima tramite Google Home Grazie

[marsergio]

Thank you for the support. We have 2 devices home and 1 of then I done the factory reset. I waiting the instructions. The another is working well again.

[GISELLE_REYES17]

Ya lo logre, lo reestableci de fabrica, pero desinstale la app de home y puse en mi teléfono Android una fecha antes del 9 de marzo, volví a instalar la app y lo intente conectar con el Chromecast y funcionó por fin se pudo, luego puse la fecha a la de ahora y ya se puede transmitir 🥰🥰💕 (recuerden darle los permisos necesarios a la app) 

[Reiofsky]

Se você , assim como eu, restaurou antes da atualização eu consegui resolver. Altere a data do seu celular para 01/03/25 efetue a configuração normalmente, assim que a rede for restaurada no Chromecast ele atualizará automaticamente. GOOGLE PODE MANDAR MEU PAGAMENTO!

If you performed a factory reset, you can still re-attach it to your "home". This will allow you to receive the new firmware with the updated CA certificate installed. Here's how: Using your device (e.g.: Android phone or whatever you have the Home App on), change the date to March 1st. Then add the new device to your home per normal. It will find it as a new device and it will connect to the network and internet again. Then it will get the new firmware when it rolls out. You're welcome 🙂
