[Stelica]

Ai reusit sa functioneze sau doar sal reinstslezi, ru am incercat metoda de instalare se conecteza dar daca vreau sa vizionez in spine ca Outdated device firmware could be the cause. 

[Danc1208]

Hi Google

thanks for the update, looking forward for the solution, so I can use my streaming services (Netflix, Disney, max, Viaplay and prime) you helped me out with saving money for I think that I don’t need to have all of the above streaming services, 

hope you have a wonderful day 

best regards 

Dan

Malheureusement j'ai déjà réinitialiser et le problème perdure !!

[Johan3]

@GoogleNestTeamit is 4 days not, just for an outdated certificate that could have been avoided. This is not acceptable for a company like google. What are you guys doing ? What is the timeline for a fix ? you are making a lot of people unhappy of google

[SrinivasuL]

Have you released the fix? 

[cstngm]

Hallo.
All my 4 Chromecasts Audio are not working.
How do i got to know, when You have resolved the problem?
with kind regards

[RyanAntonio20]

Hello Google, I'm having problems with my Chromecast. I set it to factory settings and restarted it several times. It says my Chromecast could not be authenticated. What should I do and how to solve the problem with my Chromecast?

[Josefine]

When is it expected to work again? Now we are on day 4 and still no update! 

[Leighbarlow]

4 days and still no fix. Unbelievable. My company has had to source alternative hardware for high level presentations and this has impacted us greatly. If this is how you encourage customer to upgrade then you are a joke of a company.

Will not be purchasing google products again

[Spo1805]

bonjour, une idée du délai pour obtenir le correctif ? cela fait plusieurs jours désormais que nos chromecast "anciennes générations" ne fonctionnent pas, je pense que les clients ont été plutôt patients non ? merci.

[Rv007nz]

Within New Zealand you are now in breach of the Consumers Guarantee Act.  A complaint is being filed with Commerce Commission, if a fix is not promptly forthcoming then Google needs to be replacing everyone's units.

[ゆんゆん]

リセットしてしまって、再セット出来なくなりました。

どうしたら宜しいですか？

[Zeeone]

Please help me

[Bhinda]

Not working 

[xenialjj]

It's a bit late to tell us not to factory reset or device when the only way we get this problem is to follow basic procedures and factory reset a device. Please fix this SOON. 

[corlemmers]

And the solution is......

[RENATA1]

Bonjour,

A mon avis, tout était prévu , l'arret du Chomecast était programmé, c'est pour nous inciter à acheter leur nouveau produit Google tv Streamer ( 110€ !!!!! ).

On nous prend vraiment pour des "gogo".

BRAVO GOOGLE.

[nenepapa]

時すでに遅し

電源は1度2度3度と

ルーターも含め入れ直しました。

[Hotrod9974]

I already factory reset it will I be ok 

[mikekaast]

yes, your device will be ok. Just find an old ipad, or an old android phone, set the date on your device to Mar 8, and setup your chromecast as normal from the google home app, and your all set. BUT you still cant cast anything, you will get the message:  Unauthorized device : until google fix this problem.

[Buurman]

Hi MikeKaast,

What old Androidversion wil work?

[Bottmij]

Where are we at with the fix? It’s been days since this happened, surely you have come up with a solution by now

[Hotrod9974]

I factory reset it can it be fixed 

[Villalobosjavie]

Gracias por todo

[TamTy22]

Please 🙏 help to fix my chromecast problem 

[nilyas]

Any luck bro? 

[KevinAtHome]

H i GoogleNestTeam,

would it be possible for you to open a separate thread for incoming news where only you are allowed to write ? Or is there any location, one could read about the progress without reading 5000 msgs "me too" ?

[joaop]

Hello,

I hope this message finds you well. I am writing to inquire about any updates regarding the certificate renewal for Chromecast Gen 2 devices. Are we currently awaiting budget approval for this process?

If the cost of issuing new certificates or renewing all existing ones is not approved, perhaps we could consider a less stringent security fallback for these devices instead of using RSA. This might be a more cost-effective solution.

I am just trying to assist in finding a viable solution. Could you please share any details on what might be causing the delay?

Thank you for your attention to this matter.

Best regards,
João🇵🇹
