Do not factory Reset!!!

Unfortunately you provided this important information very late.

Factory reset was the solution that was suggested in the forum for all past issues with Chromecast. Im sure many have already tried this.

[Kels2]

What happens if I have already factory reset my Chromecast?

[JohanP]

I did already a factory reset on 1 of my 3 impacted Chromecast devices. Waiting impatiently on a fix and instructions for the device I performed the factory reset on . Like that much watching tv in my bed 😉

[SammyE]

I am getting the same error on my chromecast 

How long will it take to be sorted? 

[awpoole]

hi I'm not very good at technology and unfortunately I have factory reset both of my second generation Chromecast as I did not see this come up on any of your troubles shooting as it was telling me to try a factory reset, so can you please tell me how to resolve this.

[flameofthewest]

Oops I did the factory reset before this problem was announced. Fingers crossed there is a resolution soon

[virgoz]

Please can you notify me when the authentication fix is available for Chromecast Audio.

[Pica77]

Consulta yo tengo entendido que mi equipo es 3ra generación y también dejo de funcionar anoche y no lo pude. Conectar más!!  

[Xtradeep]

So is that why my chromecast says it can't be authenticated?

[Max98]

I followed your guide in the help center.

So I did reset the chromecast. 

please help asap!

[Patrizio]

Nice... But I have already made a factory reset, cause is the first thing we try after restart it and the router so... Please fix also for the people made the reset. Thanks

[Bicienz]

Any news?

[Danzadanzis]

Hello, I didn't know what was going on, so I listened to Google and tried a factory reset. Can you advise me what to do now? Please

[Sean2025]

Change the date to 7 march and you will able to reconnect to WiFi but when you try to cast you are going to have this message untrusted device firmware outdated issue 

[Sean2025]

So I wait a firmware update or anything to work Google 

[Alfredocastelli]

No se puede configurar Chromecast 

[Sean2025]

Or I buy a Xiaomi stick it's more cheaper 

[Chatice]

Chromecast parou de transmitir, ao tentar reconectar manda atualizar o app home, já atualizei, reinstalei, recetei e nada . Vou tentar ascender uma vela agora, cadê a solução?

[Patrizio]

Is a world problem from yesterday. Here the same in Italy. Google is working to fix.

Somewhat late to get the warning of not to perform a factory-reseting of the device now... 👎

[Leandro73]

De repente, no conecta mi smartphone con el aparato del chromecast. Andaba siempre muy bien por años. Y de repente no lo ouedo hacer andar. Intenté todo tipo de reinicio: la aplicación de Home, el reinicio del aparato, cambió de tv.. Todo y no funciona. Lo reconoce hasta que me sale un cartel de que no puede reconocer el chromecast.. Como que no está autorizado.. Muy raro 

[Adlfg]

Any news regarding this issue? It's been 24 hours now..

[Larryot]

Kinda pointless to red banner "do not factory reset your device" when it's in the list of troubleshoot solutions. I'd imagine most people have done that at this stage, it only serves to spook people. 

[Danzadanzis]

Please, how do I change the date to March 7th? I'm not at all tech-savvy. Please advise me.

[Cynlee]

I can’t figure out how to change the date either on my iPhone - but we really shouldn’t have to 

[Cynlee]

Go to General/settings/ date & time/ set manually - unfortunately this did not work for me in my ipad 

[Danzadanzis]

Please, how do I change the date to March 7th? I'm not at all tech-savvy. Please advise me.

[Sean2025]

On settings On a android phone search date put the phone on march 7 and reconnect the Chromecast 

[Erasmus]

Why this? Would the problem be solved? 

[oitaus78]

I already done Factory reset for 2 chromecast. Impossible to reconect. After changed the system date on 5th March the instalation works. Thanks

[Wen2]

Already factory reset five times grrr

[Sean2025]

I have doing so but it's dangerous because it's possible to brik the device

[Jen26]

This has been going on since 6pm yesterday! I have spent the last 24hours trying to resolve this myself with rebooting everything and trying to contact you , I’ve been in a virtual queue all day for it to just disappear at the last minute! I need the chromcasts working . What is the solution please ?!?

[FortisNAD]

Too little too late, factory reset was performed out of frustration on lack of communication and availability for support!

[Jen26]

How will you keep us updated ? As if it wasn’t for coming online to try to get a solution myself I wouldn’t have even seen this message !!! 

[oitaus78]

Both chromecast are reseted. The wifi router too. Hope to recover all after fix and instructions. All the day I reseted devices, installed, unistaled the Google Home. 

[Rw6]

What is your expected time range to have this fixed?

[Kels2]

I have managed to get Chromecast reconnected, unable to stream anything but at least it's back online.

I have Samsung device went into settings

General settings and manually reset the date went back on to home and connected Chromecast straight away.

Thanks for the help just waiting for fix now.x

Hello all!

I just wanted to say that's really a pitty not able to manage SSL certificate properly on millions of devices that we, customers, bought.

I also wanted to point out the poor communication from Google linked to this issue.

I spent almost 2 hours to debug it and to understand that the issue was not coming from my side.

I'm really upset.

I wanted you to know.

Regards

[sherik]

How did you determine it's a SSL Certificate issue?
