Hola reinicie mi dispositivo ya que como no funcionaba pensé que era algún error por favor necesito asesoría para volver activar mi dispositivo, agradecida 

[uanidemalaga]

Parece un fallo global, un error con los certificados de seguridad solo para la 2nd Gen curiosamenta la 1st Gen funciona 😕 

[Alhrik]

Well oops.  I have already factory reset the Chromecast that suddenly stopped working, since this was the fix for many issues in the past. Looking forward to a fix. 

[Neb32]

When troubleshooting, first thing is reboot. Second is factory reset. Too late. A notification in the home app would have been helpful. What's my options now that my devices have been factory reset? 

[Allan_t]

Need som help regarding Chromecast

Have been using them for years now but within 2 days at least 4 have stopped working.

I have tried to factory reset two of them but during the setup is says connecter but only to to can't connect to Chromecast.

Have also tried to restart the router. Nothing seems to work....this simply can't be an coincidence.

[Derik64]

Its a bug. The certificate is expired and google is working on the problem. Same issue with my 3 Chromecast Audios. 

[Chicafresa]

Google made a statement and this is a known google issue. No one with a 2nd gen can use them right now. This link explains in more detail and if you like me reset your device to fix it, there is advice on how to remedy that issue. Good Luck!

[Aebav]

Of course MOST of us have factory reseted the device.

What should we do??

[Momo4]

I already factory reset because that is what google told me to for troubleshooting. I then found out it was an error affecting everyone. What can I do? This is a rude way to try to get people to buy the new version.

[Geen1]

Please let me know how to reset it up as I reset the chromecast (using Android to Smart Tv, from Google Home app, thanks

[JDL1103]

I have 3 Chromecast devices that are not working since yesterday afternoon. I rebooted one and did not work. All show offline in Home app. I factory reset one and can't reconnect to Home app as it indicates "Can't Authenticate". My account shows 2 cases being worked on but no info as to status to get my 3 devices up and running again for streaming of video & audio.

Please advise ASAP as many of home's entertainment is Google operated w/devices & HUB.

[DLHOUGHTON]

Come on Google this isn't good enough. You tell us 3 hours ago not to reset our Chromecast yet online that's the first thing it tells you to do. If mine is broken from doing a reset I expect a whole new Chromecast in the mail thanks 

[Greenpeace]

What message appears in your screen? I did everything already. 

[NotUrMomma]

I know. It really sucks the Lama’s ass. I’ve tried just about everything.. No Google recommendations from me!

[Julesxxx]

[Abz05]

Same problem here aparently it’s a problem world wide with chromecast

[Jess36]

Yo también lo restableci de fabrica, ya que es lo primero que te dije Google que debes hacer. Espero que Google se encargue de resolver este desastre y que mi Chromecast funcione, pese a haberlo reseteado.

[Carsten-1002]

I can't get chromecast to connect to router. It's been working fine for years but suddenly it stops connecting. I've tried turning chromecast and router on and off. Please help in advance, thanks Carsten.

[Skcarsane]

[Irena]

I have the same problem. it was working fine for years but from yesterday it suddenly stopped.

[Jk3ebk]

Unable to cast with chrome cast is there any fix yet?

[Sanya]

I’ve reset my chromecast, updated my phone, updated my apps, made sure my local network access is on, and I still receive this message:

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 privacy settings and try again. 

Local network access is definitely on. i don’t know how else to solve this issue. My phone used to connect no problem. Chrome cast light is white, both devices on same wifi

[Jensa]

[Klacasse1968]

How much longer?? It's been 7+ hrs

[Abz05]

I have already done a felactory reset trying to fix the issue is that going to be bad?

[cawauk]

Same issue here. Logging a message so Google can extrapolate an rough number of how many users they've impacted.

[Olby10]

Hello? 24hrs here.... should you say something or is just a trick to make us bought a new device?

[anglophile]

How, exactly, will we be informed if we factory reset the Chromecast. 

I am sure many many people did so because we were following the Help screen list of what to do to resolve the issue.

[Hurte]

Estoy de vacaciones y contaba con este dispositivo, den una respuesta a los usuarios o empiecen a regalar Google TV para todos 

[Adav]

So you guys wait a full day after JillG tells us to factory reset... to tell us to NOT factory reset... Too late.

[Stef69]

Exactement le même problème depuis hier soir...

[Marymartins]

Altere a data para o dia 07 de março

Feche o house e todos os aplicativos após a alteração da data e tente novamente 

[Skcarsane]
