Hi, 

This happened to me last night and I have been banging my head since. How are you going to let us know the fix is in place?

stiamo aspettando una soluzione da parte di google per il ripristino dello stremaning. 

Se hai ripristinato il dispositivo alle impostazioni di fabbrica e non riesci ad associarlo nuovamente , porta la data del dispositivo dove hai google home ad una data antecedente l'8 marzo e vedrai che riuscirai ad associar nuovamente il dispositivo.

[Lily8]

Of course I factory reset mine, as it is the normal wayto fix...

Will you explain us how to retrieve usage after the issue is fixed, also for people who factory reset?

[Mrbaseball77]

Se hai ripristinato il dispositivo alle impostazioni di fabbrica e non riesci ad associarlo nuovamente, porta la data del dispositivo dove hai google home ad una data antecedente l'8 marzo e vedrai che riuscirai ad associare nuovamente il dispositivo.

per ripristinare poi lo streaming ci dovrà pensare google

My beloved (and nowadays rather rare) Chromecast Audio stopped working yesterday (as per your info). Unknowing of your info I reseted it today and started a new install. Google home will find it, for a brief moment it says it's connected to the wifi and my router sees it sending and receiving packages but google home states that my Iphone/IPad can't communicate with it. I have gone through the entire troubleshooting process but alas no luck.

Now I saw this. Is there a chance I can get an alert when you have solved this issue and what should I do?

[NandoAdViper]

To late, my son reset to factory... What should I do?

Il est un peu tard pour nous conseiller de ne pas réinitialiser 🙄
Votre communication est trop trop tardive 😤

[RENIE496]

Since yesterday the app does not work anymore.  I followed all instructions. Reset chromecast. Reset wifi. Reset app Google home. Check iOS update. Privacy settings. Etc etc. The app says: Could not communicate with the cast with your iPhone. 
I see more of the same issues in the posts!!!

[kj2233]

im having the same issue here…

[pbelcher]

As with everyone else I have already factory reset my device and it's not working 😢 

[Johan3]

when will this be fixed, I just spent 1h30 trying to reboot and reinstal everything before II saw this thread.

[JosiBaroli]

Chromecast parou de funcionar ontem, erro de autenticação. Já deu para perceber que o problema é geral e mundial, o assunto está em todos os fóruns na internet.

Estou aqui apenas reforçando e esperando que vcs tenham uma posição para dar aos consumidores. 

[Wany]

Nossa, é geral isso!? Como vai ficar! Quando e como será resolvido

[andbeg]

Не працює як у всіх, немає автентифікації ,цікаво чому адміністрація не реагує на звернення?Чи їм це не цікаво?

[Cmmonte]

Tengo problemas en mi Chromecast, me da error de auténticacion al buscar dispositivo.

[Lom]

Many people have the same problem. Chromecast connection failure. Does anyone or Google have a sollution?

[BadFlash]

No... google will have to provide a firmware update or disable CC authentication for affected devices.

[Milmagura]

How I know when the problem was solved?

[Crist]

Desde el día de ayer el dispositivo estaba como pegado y lo reinicié y se me borró de la aplicación de Home y ahora intento configurarla nuevamente el dispositivo y me dice que no se puede autenticar el Chromecast 

[alvarenga7udb]

Here's a notification from Google Nest Team... in a few words... we have to wait 💀 https://www.googlenestcommunity.com/t5/Streaming/Regarding-an-issue-with-Chromecast-2nd-gen-and-Chro... 

[Zarkur]

• Chrome cast non si collega e non identifica il cellulare non capisco quale sia il problema

[SuzieQnick]

Min chromecast har plötsligt ett meddelande: "tillgänglig för vissa videowebbplatser".

Vad menas med det? Det har aldrig varit problem förut. Nu kan jag inte casta varken från mobil (android) eller från dator (PC Windows).

Behöver hjälp!

[Filur]

Har samma problem. Vid kl 19 igår (9 mars) slutade båda mina Chromecast Gen 2 att fungera. Är tydligen ett globalt problem. Har att göra med att nåt certifikat har gått ut vad jag läst. Men har inte sett nån information direkt från Google eller hur dom ska lösa det. 🤔

[HerrValnöt]

I just did a factoring reset....😭

[Davidio]

Same issue. I can not use my Chrome device. I hope it will repaired soon.

[winny]

Buongiorno anche io mi sono ritrovato con lo stesso problema degli altri, purtroppo non sapendo nullo ho eseguito il ripristino delle impostazioni di fabbrica, il messaggio che compare è impossibile autentificare il dispositivo.  Attendo vostro supporto per risolvere il problema grazie.

Hi,

I have had a Chromecast audio working with a hifi system for several years.

Suddenly it does not longer connect to the local network.

I have tried resetting network and chromecast.

1. the chromecast does not seem to reset. It is solid white after reset after blinking orange, indicating that is on the network?

2. If try to set it up new, it recognizes the chromecast and goes though the stages and connectc it to the network , until just after hearing the connecting sound after connecting process has finished, then error message comes up as described in 3 below.

3. The error message that comes up is that my iphone will not connect until I have allowed google home access to local network, which it has when I go through my general system settings.

4. I have tried to connect to the chromecast network directly without success. I see the chromecast wifi network but also get a error message here.

Does this mean the device has failed? It seems very strange that it suddenly no longer is able to reset properly and not connect anymore.

Anyone else with the same problem or who has a solution???

[KTunare]

I just ran into the same problem..... Following.

[wesmag4]

Let me know if you figure it out. I have other google products working so its definitely this particular device failing not my network or phone settings

[EC3]

Google is working on it (they say). See Reddit for more info: https://www.reddit.com/r/Chromecast/comments/1j7lhrs/comment/mgzcw4e/

Pareil bloqué depuis hier soir le 10/03, on attend la résolution….

Hi ,

Before reading this post I have factory reset my device as this was normal practice. 

Please advise on how to proceed to keep using my Google device. 

Thanks 

[Aaalexxx93]

I did factory reset mine...

[Danishmadara]

I factory reset mine like 10 times lol too late.

Anyone else in the same boat can change the date to march 6th on their phone so they can add the chrome cast again and hopefully receive the fix

[Martin721]

Well. Here I tried to change the date to 6 march, but with no succes...

Ive gotten very disapointed with google, and how they make customer service.

Will certainly look for another device to watch tv..

Thanks for nothing google

[moisie]

You surely will never encounter a situation like this with another device from a different developer, I'm sure ...

[Antonio64]

Hello there,
