Had the same problem since last night until now 😮‍💨

[arnaupg86]

Mismo problema desde ayer a última hora de la tarde, tanto para Chromecast como Chromecast Audio.

[Brumby66]

Change the date on your phone to the 7th March and it completes the setup 

It still doesn't stream but Google says they're working on it

[Rashed206]

Same problem, I thought it was only my device

[CrookedBadge]

Google seem to be aware of the issue, and are working on fixes, both for people who haven't factory reset Chromecast and for those who have.

It has been 2nd day since the issue happened, there's no feedback or even a notice to know what's going and if they are really trying to work it out, but i hope they can fix it soon. 

[fm4]

same problem. stesso problema ! ho contattato l'assistenza dicono che stanno lavorando per risolvere. google service contatcted inchat tel me they are working but at the moment they don't now when.

[Kernel64]

Funny how google can just lock us out. I was thinking about upgrading to a google tv but not anymore.

[BadFlash]

It’s a SSL certificate valid for 10 years that simply expired … now , do I want to wait for a fix that can come within 25 hours to a month or more ?  Or no fix ?  

[FedeCecco]

For those that are stuck with a Chromecast bricked because of a factory reset and cannot reconfigure it back, do this: change your phone or tablet date back to 1st of march, before the problem with the certificate started.

Then in Google home you should now be able to complete the configuration. You won't be able to cast anything else than your screen, but at least you wouldn't have a bricked device.

[Anonymous]

Efectivamente, cambiando la fecha del teléfono google home puede configurar el Chromecast Audio, aunque  sigue sin funcionar. Gracias, en cualquier caso

[Carebear00]

Thank you! This worked

[Wd1980]

Same here, all 4 tvs and all 4 chromecasts have gone off. 

All saying can't communicate with chromecast

[Kit2000]

Same here kmt😡

[pawan2]

facing same problem. it is very irrirating could not sleep because of thinking about it. Google plz solve it asap.

[Pepet]

A mi em passa el mateix desde ahir

[Mortimerca]

I have the same problem with my 2nd Gen Chromecast. Im fron Argentina.

[Slavitch]

You absolute idiots.  You need to ship replacement devices to everyone affected.  Your own instructions told people to factory reset the device.  Now they are bricked due to your negligence.  You broke it you fix it.  Replace every device or expect a class action lawsuit filed this week.

[vilourdes]

The procedure said to reset to factory. What do I do now. Is there a problem if i followed your original instructions? 

[TimBob]

Thanks, pal. Your online troubleshooting page includes factory reset as a step.

How 'bout this as a suggestion to the Google team: Do Not F-ck Up Chromecast. Oh, too late?

[raeckell]

HOLA. QUIERO SOLUCIONES

[Tameracabrera]

Add me to that notification same problem #

[LP9]

Det gick inte att autentisera Chromecast. 

[Lily7]

A mí me pasa lo mismo desde ayer.

¿Alguien sabe cómo solucionarlo? ¿Y ese alguien sería tan amable de compartir esa solución?

Gracias!

[Itlab19]

I am using Chromecast sense 3 years but since 2 days I found an error when I connect YouTube with Chromecast I reset the device and then when I trying to connect with home app see error we could not syndicate your Chromecast. Please help 

[alebensadon]

Since yesterday, many users with Chromecast devices reported an error when trying to configure the device in the Home app.
The error is authentication.
Something like this: ""Your Chromecast could not be authenticated. Go to support.google.com/chromecast for more help troubleshooting this issue."
It is a global problem for Google with Chromecast devices.
Error reports have been reported from several countries on 5 continents. 
Probably due to a firmware error.
Let's hope they solve it soon.

[MagdaGwarda]

Yes!!!! Since yesterday evening I have this problem ,though my chromecast is old ..have to buy new..but looks like not only me struggling !!! Hopefully it will back to normal soon ! Last episode waiting to be watched 😭

[Lom]

I threw away three hours fixing it, in vain. Nothing we can do, it seems. 

[Lom]

Thanks for your answer. 

[Arunodaya]

I am have been trying to troubleshoot and break my head since whole of the evening today. Tried restting multiple times but the error remains same. Thought of buying a new one as well but not getting it anywhere available online. Its kind of scary for me. Hope Google takes it on priority to fix this issue at the earliest. 

[NeilJames]

This worked for me: 

https://mensfeld.pl/2025/03/bringing-your-chromecast-back/

[ZM22]

I was able to restore connection. Great research.

[Beitler575]

Worked for me too! Thank you so much 

[NeilJames]

Apparently, they're working on a fix. Those who followed the troubleshooting guide for Chromecast will find the instructions just make it more difficult..

[Lom]

Yes, wasted a lot of time.. 

[vjrocks87]

is there anything we can pin for notification? so we keep getting update? i love my chromecast and dont want to throw away. 😞 its working fine just not casting it. 

[Jimlaad]

Follow the link posted by NeilJames below, the fix works.

[svgulab]

I am from India I am also facing the authentication issue for the last 12 hours

[harpreet4483]

I am also from India and facing same issues of authentication error from last 10 hrs

[Cb14]

I am also having that issue, I have tried with 3 chromecast and noticed that the ones made in China are the ones that are not being able to authenticate but I have another one made in Thailand and it is working at the moment, they all are the same model NC2-6A5
