I can confirm that the workarounds posted on Reddit and elsewhere will indeed restore Gen2 casting from Android devices and Chrome browser (sorry, iPhone users). Had mine back up 'n running by Monday morning. Not perfect, but for those who are impatient (and tech-savvy enough), it's a viable option until Google issues a proper security certificate fix.

[Mtaylor09]

The google Home app recommended the facoty reset!!  What are we supposed to do now?

[Technoidatx]

Too late. I already did a factory reset. 

[annie888]

uggh -  too late!  factory reset done 2x!

[plchris00]

Oh, thank goodness. I thought I was loosing my mind! Although,  in a attempt to fix it, I did factory reset it. 🫣

[Marielaale]

Hola, el aviso de no resetear el Google crhomecast llego tarde, ya por razones obvias de que no informaron que era una caída global, realice el reseteo. Ahora no puedo usarlo. Que pasos debo seguir para que funcione?

[mhill]

I'm upset that the 1st gen Chromecast won't work anymore. Mine is perfectly fine, but doesn't work now because Google decided to stop supporting it so that we have to buy something else! I will not be replacing it with a Google product!

[Flaxxq]

Please fix, Chromecast Audio not working.

[Di007]

Thank you

[DaveBro]

Thank you for addressing this. While the community has alternatives for the 2nd Gen Chromecast, the Chromecast Audio remains quite unique and difficult to replace. I hope to be able to use mine again!

And please if the support group has any leverage, tell them to put out a new replacement for the Chromecast Audio. If it is $50 or under it will sell a lot. Heck, I'd buy five myself!!

[Anonymous]

I already factory reset now when I try to set up it won't authorise 

[jkwrvcdb]

I reset one of my devices the morning of the incident. Please provide a solution for that scenario as well?

[Wooshu]

Seriously, folks. CC Gen 2 & audio are cheap gadgets released 10 years ago this September & long since discontinued. It's amazing they're supported at all. 

[letoute]

Chromecast Audio was rather special en good!  When connected with optical cable to a good Hifi stereo amplifier and good speakers, sound was amazing.... There are streamers on the market, yes.... but much bigger and more expensive....   By the way, you can stil find Chromecast audio new in box and sealed on Ebay! Bought my 3e one four months ago!  Millions of users!

[TEXAS25]

Please send another email update when fixed. 

[Zorg-Eex]

Thank you for jumping on this and sending out the notice quickly.

[enahardy]

i hope this gets fixed ASAP. its been really disruptive with my kids daily streaming usage.

[NoobNeels]

While they are looking at the code, please check on the setting up a new device code. It really sucks to add a device on a dual band wifi. Have to try several times before it accepts the connection 

[abouabla]

You're making a big mistake, Google. Why did you do that to your customers?

What can we do now?

[memx]

Rule #1 - if you create a new CA, you are responsible for updates to all devices that use that CA. The update MUST be automated.

This wouldn't capture devices that have been unplugged..

It's a tricky problem to solve. How do you ensure the device is getting it's CA updates from a valid source? (ie: Not an hacker)

[Idky]

Well I just got notified about and I had no idea you guys had broken it so I had already done a factory reset.  I expect a fix soon.  

[bmksharif]

I did reset my Chromecast 2 to factory so please advise how to fix this issue so when the correction is made mine will work, thnx 

[kapoorabhinav]

To undo your reset (so the device is back at earlier date so that it can be "verified" and connected to your wifi again [and can wait for a solution by Google]) you could apply the following steps:

- Set the clock of your mobile phone manually to March 7 (i.e. at least the day before the problem occured) > Settings clock, date/time > disable automatic date/time setting and change manually to March 7
- Start your Chromecast ("CC") and reset it again
- Now restart the connecting process with CC from Google Home
- The CC will boot up and "verify" with your device again, connect to your wifi again and the stanard screens will show on your TV again
- Now your CC is back alive except for the fact that it won't let you stream anything due to the existing certification problem at Google but it can now wait for Google's fix to come
- Don't forget to switch on "Automatic time/date" of your mobile phone again

I tried these steps and it worked for me..

[StrangeCat]

Super. This is good advice.

[Emusk]

Also do not except sweets from strangers 

[Me-again]

"Except"? I think you meant "accept "??

[Doc_Abhishek]

@GoogleNestTeam whats the update guys?? Its already been 3 days. Please do something about this issue asap..

[FredT100]

Replaced mine cheaply with a Roku Express. The only thing I miss about Chromecast is the nice wallpapers 

[Batty876]

To Kate

factory reset mine 

Do I just bin it now

[kapoorabhinav]

this is basic monitoring process gap/issue.. we expect to have better monitoring solution in place.. did not expected it from GOOGLE... 

[Eko1]

Holy molly, the endless reply to this. Leave me alone google!!!! Just work

[fairweatherfan]

Thank you for your tardy notice.

Because it failed and there was no guidance until March 12, I purchased another device. Will you be reimbursing me for this now unnecessary purchase which was caused by the emergency failure? 

[JuliCamara87]

Team. I have already done a factory reset because I had no idea what was going on. Can you please instruct me how to reactivate my chrome cast please? 

[namansonkhiya]

We couldn't authenticate your Chromecast.

Any help regarding above issue ?

[Emusk]

Has it started ticking yet?

[camillyv]

Não estou conseguindo finalizar a confirmação do meu dispositivo 

[rfumis]

Também não estou conseguindo. Já tentei resetar, tirar e recolocar na tomada, nada.

[BinaPS]

Mesmo acontece aqui. Parou de transmitir hoje por volta das 16h (horário de Brasília).  Resetei  chromecast, modem e celular. Nada funcionou.

[Kris_1992]

O meu também apagou. 

Deixou de mostrar as minhas fotos. 

Pensei que tinha perdido a ligação ao Home e fez uma restauração e já não consigo a ligação ao Home.

[Al2507]

Lo mismo. Dejo de funcionar. Al reinstalar da error de autenticacion.
