Too bad most of us followed the existing trouble shooting advice and have already factory reset our devices.

Wish there was a way I could have known this now that I have been trying to figure out for hours and hours why I couldn't watch TV. Just stumbled upon this forum. 

[Lerv]

I still can't authenticate my Chromecast device. Please provide instructions or resend a replacement device ASAP. Thank you.

[HauntedinNY]

That's the same message I keep getting too! Annoying as anything 😞 

[Dotgal]

Still no fix? Come on Gooooogle... I want to stream my stuff 😫 

[MarceloM1979]

Any updates on this issue? 

I've found this after factory reseting one of my chromecasts... would've been great to have a notification on my google home mini, google home app, mail, etc... 

So in any case... is there any solution in sight? I have 3 or 4 of these accross the house (toghether with many other smart controls I'm starting to fear of)

PROBE ESTA SOLUCION DE CAMBIAR FECHA DEL CELULAR A 5 DE MARZO Y FUNCIONA 

[Cc2025]

PERO NO FUNCIONA PARA CONECTAR APLICACIONES SOLO TE MUESTRA EL MODO AMBIENTE 

[Babi1998]

Poxa descaso total com o cliente, 2 dias com crianças em casa sem assistirem por que dependemos do chormecast pra transmitir os desenhos na tv, fiz o hard reset no aparelho e agora não tem oque faça ele conectar, não consigo suporte em lugar nenhum, palhaçada heim!!!

[Mcah]

This is ridiculous that it hasn't been fixed yet! 

[TrishJ]

I am still not able to connect to my Gen 2 Chromecast in New Zealand. Have tried everything and did a factory reset last night as instructed by customer services before seeing not to. Is this close to being fixed? 

[Gustavoden]

Yo reinicie a fabrica y no autenticada. Cambie la fecha de mi celular al 7 de marzo y puede autenticado. Pero al castear nada funciona. YouTube, netflix, max... 

[Semy]

Boa noite. Eu reset e agora? Mas no fim da problema.

[Cc2025]

NECESITO SOLUCION MI CHROMECAST SIGUE CON EL MISMO PROBLEMA DE NO PERMITE AUTENTICACION DEL DISPOSITIVO- SOLUCIONES NO AVISOS TARDE DE QUE NO REESTABLEZCAMOS DE FABRICA COMO YA LA MAYORIA LO HIZO- NECESITAMOS SOLUCIONES URGENTES- PARECE UN MAL CHISTE ES VERGONZOSO YA

[axmir]

When will Google fix this problem and how will users be notified, especially those of us following Google's standard troubleshooting advice and factory reset?

[Semy]

Eu resetei e parece que ficou pior... Fica informação na tela instalar o app e não instala o home da erro no fim . 

[Macoinnit]

I followed the Google troubleshooter and factory reset it after trying all other suggestions. This is a pr disaster btw

[Ckelly1960]

Will I need to check back on this site to get the fix or will it be an automatic fix??

[Semy]

Faz  2 dias sem conexão com o Chromecast 

[Maurício67]

Aparentemente há conexão no Chrome com a tv o problema me parece estar em transmitir do celular para o Chrome e consequentemente para a tv. No celular aparece uma mensagem "falha ao estabelecer uma sessão no aparelho selecionado SSCR-S4010..., eria este mesmo o problema. Temos que aguardar a solução por parte do Google??

[becca2]

Thank you! 

[Bingoman85]

Still no resolution for this... I wonder the whole point is for ppl to buy new devices... 1st they fuc*ed the Pixel 4a now old chromecasts.. Nice going Google

[NeoDC]

It’s been 2+ days since my ChromeCast got glitchy. I woke up the next day and it seemed stuck. I reset my WiFi router, did a hard reset on my phone, and reset my ChromeCast as anyone would. I tried contacting support but of course got nowhere. I now find this thread today. Google is very unprofessional in that I had to dig deep for hours to find out this is a worldwide issue. If not for this thread I’d still be wondering why I can’t stream or use my ChromeCast. Totally unacceptable. Fix it. NOW!!

[becca2]

same here! I came across this thread by accident after hours of trying to connect. 

guess we have to wait for them to miraculously contact us 

[Iamronchii]

I already reset all my devices... Please fix it tried with android and ios

[eahicok]

Thanks for the minimal update-it is ridiculous that this information has not been pushed out via the app. That way instead of trying repeatedly & resetting devices to factory reset-the information would have been available. Very poor customer service level & not what I expect from google. This is barely Roku level of service!!!!

[redwood822]

This issue has been going on since Sun morning just after the time change. How long before this issue is fixed? We might be better off starting a class action lawsuit and switching everything over to Apple devices. If Google can't get it fixed in a timely manner, time for a major boycott of everything Google and Android. 

[MessiaS10]

Que hacemos si ya reestablecimos de fabrica, tal como indica el procedimiento habitual ante estas fallas?

Cual es la fecha estimada de solución?

[Mishonio]

This is absolutely unacceptable.

a corrupt update disables all chromecast gen 2 devices (and perhaps other generations as well)

what’s the eta for a fix? What’s the defect case number? How will all impacted be compensated?

thx

[Mum1]

But late for the Do not reset msg. When all of us know that's the first step in trying to fix your buggy nonsense. So the majority of us have done so already. 

[Ravi009]

Pls post solution ASAP for the ones who did factory reset

2nd generation Chromecast model NC2-6A5: I reset the device to factory default, following the series of suggested fixes issued by Google. As others have mentioned, I could no longer connect to the device to set it up. Following the advice noted in this thread, I set the phone's date to March 6. I was able to connect to the Chromecast and get it back on WiFi, so others that mentioned a certificate expiry issue may be right. I still cannot connect to the device to stream anything, but with fingers crossed , Google will be able to push the fix to my device.

[TigaroT]

This article was impossible to find, you need to add a link to your support page with this. What do we do if we already performed a factory reset as per your support page instructions?

Edit: per the instructions in the comments. Change the date on your phone back to March 6th and you will be able to set it up. However until they fix the expired certification, the moment your chromecast connects to the Wi-Fi it will realize the date is the 10th and it's past the certification so you will not be able to stream. Hopefully when they renew this your device will be all ready to go.

[Mojo1491]

I am nowhere near an expert on this, but I followed what I read from others and it worked in order to allow the device to regain access to the Internet. Here is my experience:

I have a Gen1 CC audio and it’s not connecting. Same error “Not a trusted device” I already made the mistake and I did a factory reset.

[Tiagomartins]

Restaurar aos padrões de fábrica foi uma das primeiras coisas que todo mundo fez após passar muito tempo tentando conectar sem sucesso. Agora, mais de um dia depois da falha vocês avisam isso.

Hi There
My Chromecast stopped working from my phone and iPad yesterday.  I reconnected it and it keeps on saying enable local networks.  They are enabled.  Is this the problem you are currently trying to fix?  

[Gorgeous_LadyZ]

I have been having issues for 2 days and did a factory reset loke the original Instructions suggested. Now I'm stuck when this matter be rectified
