Thank you I've 3 Chromecast audios in my home it was a joy this morning one works the other one that was connected the same as the one that works doesn't. 

Sadly I removed the third one off the Google home app and now it won't come back although it's connecting to my internet. Shame this headache still goes on. 

Still I'll count my blessings out of three one works Yeee Haaa!

[MB1f23]

Hello, I factory reset it, and it still isn't working. Can I get some assistance? 

[Demy]

Please fix it as soon as possible 

[Lebert32]

My device shows it being offline, I presume this is the same issue?

[Tbee3]

Is there an ETA for when this issue will be resolved? It has been days!!

[77calimero77]

No Solution yet for those who have factory reset ? ( Which this this action proposed when you have connection pb , so i m sur most of yhe chromecast owner have done it....)

[Apermyr]

I fixed it by charging Date on my tablet.

Date 8march.

Add device in home app.

When the add process started and stopped.

Then I manually connected to cast device wifi, and restarted the add process.

Needed to do this 2 step, since wifi does not allow internet connection with faked Date...

Hope it will work for you aswell!

[KeesHeyn]

How much more time is needed???

[Dochi]

How many more days ?  Today is already friday? Its been more than 4 days. 

[ms1304]

will google be fixing chromecasts that people eneded up resetting, considering no one knew anything about the outage?

will google actually post if there is trouble shooting????

[Cnr1]

If you change your phone date and time to when your chrome casts last worked then go on google home and re add your chrome casts, follow the set up on your device , then it will be ready for googles update, it worked for me 

[Radu32]

you piece of **bleep**....

[Ricce]

Eu fiz  a restauração de fábrica, como fasso voltar a funcionar? 

[Ank12]

Any update 

[Tcannon]

What does “connected” mean when you say “your device must be connected”?

Connected to your phone? Wifi? Google Home?

Part of the issue is that in Home, my devices say they’re not connected.

[Rozalia]

To wifi I think

[Tineke]

Ik heb inderdaad bij de eerste problemen 3 dagen geleden mijn chromcast op fabriek instellingen gezet hoe kan ik het weer opnieuw instellen?

[Rozalia]

Ja precies, dat bedoel ik ook. Ze waren veel te laat met de waarschuwing om niet naar fabrieksinstellingen te zetten, ik heb het ook gedaan en ik ben bang dat dit niet meer op te lossen is. Heb gisteren maar iets nieuws gekocht, komt vanmiddag binnen en kan ik het installeren.

[Maricarmiralles]

I thought my chromecast was broken until i read this.

[Cláudio]

Ok, fico no aguardo 

[Apermyr]

I fixed my reset with:

chansen Date on my android tablet to match 8.

Adderad new device via home app.

When it stopped!

I connected to Chrome device wifi, and startade a new add process.

Incorrect Date on device, as a wifi problem where bypassed without problem.

Status. Device configured, and I'm back with certificate problem, but cast devise connected to wifi, as if I had not performed a reset!

Might work for other!

[77calimero77]

Workef for me eather but still not working cause not update and doen't work for it purpose ... The update is automatic? When does it come , do you know ?

[Rozalia]

About the factory reset..................when the chromacast is'nt working you follow some steps and one of them is the factory reset. We all were'nt aware that it was a greater issue this time and it would'nt work. Most of us , maybe all, did the factory reset. The warning  not doing it  came much too late

[pactsantos]

Hello,

I have two gen 2 devices and, today, one of those start working. The other still not working.

[Jen1968]

[Jen1968]

[mark43]

[Awais6237]

How long will it take . 

[Estuaire]

Toujours en bug aujourd'hui 

[Eduard]

After resetting the settings. The device does not connect.

[Dilemma1001]

On day 1,  I was too lazy to reset my devise and checked online if there was an issue. Well done me !! hopefully my “could not be bothered” attitude saved my two fav devises. Chromecast and chromecast audio. 
Loved seeing googlenest post a message today about a fix being. Music to my ears. (Ever hopeful)

 However, after 4 days of getting messages to just only check my internet connection, Tonight, I have the same message everyone else had about an untrusted certificate. Weird that I get this message when the fix is being sent out . I know we are at times behind in Australia  but geez I miss being able to cast shows and movies and music. 
Perhaps it is time to watch those dvds I have been meaning to watch.
At least my DVD player still functions after 18 years.

Complimenti al team per la tempestività con cui sta lavorando per risolvere il problema. Facendo parte di coloro che hanno ripristinato le condizioni di fabbrica della Chromecast di seconda generazione, della quale non si riesce a portare a buon fine la riconfigurazione, confido in una soluzione in tempi rapidi che ci consenta di rimettere in funzione il dispositivo.

[EDUJACQUE]

Please, Let inform with more accuracy when we can espect to have our device working again. Its is frustrating when this is not working. It has been past 5 days now without fixing this and I have spent hours trying to find out what happend.

Thank you

[LisiMN]

E o que eu faço se restaurei as configurações de fábrica? Agora ele nem conecta, como vai receber as atualizações???

[Rafinha25]

Quando for resolvido esse problema vocês vão entrar em contato comigo como, pois estou aguardando a dias e nada de resolver 

[Pitbull]

I wish I knew this situation as I have done a factory reset 

[Anonymous]

既にリセット何度もしてしまったんですが、戻りますよね？

[ericat]

my chromecast no longer appears on Google Home. It appears connected, though. Will it receive the update, or do I have to go ahead with the silly "change date on the phone" hack?
