Hola! yo fui uno de los que restableció de fabrica el chromecast. Sigo sin poder conectarlo. Llego a la parte de establecer conexion de red wifi, luego indica conectado pero aparece una leyenda "se produjo un error" si bien es posible que se haya configurado chromecast, no pudimos comunicarnos con ese dispositivo desde tu iPhone... 

[CristinaC1987]

Devolve lá fecha al 07/03, en tu configuração, logo configurelo normalmente. Cuando finalice a configuracion, devolver los dados além atual. Ejemplo; 15/03 y luego espere mientras chromecast descarga automaticamente lá actualizacion. 

[Facuab]

Donde modifico la fecha de configuración?

[Cente]

EN EL DISPOSITIVO... CEL TABLET

[RodrigoB]

Mudou o número do chromecast mas ainda não está sendo possível autenticar

Did you do a factory reset as part of your troubleshooting procedure? If so, then you need to do this:

O meu ainda não conecta na rede wi-fi 

[supratim29d]

Issue is fixed. Please keep your TV on after connecting to your Chromcast. Google will push the update and system will automatically update and your Chromcast will start working after few restarts.

Thank you Google!

[Pranv]

What if we did factory reset as part of troubleshooting and i did the same and i face error, we couldn't authenticate your chrome device,  could you suggest if you come across this problem 

[plex123]

Change the date on your phone to before 8th of March, then configure the chromecast in Google Home app. As soon as it can connect to your WiFi it will update itself and start working again, and then you can change back the date on your phone

IGUAL

Qué pasa si restablecimos la configuración de fábrica como parte de la solución de problemas y hago lo mismo y me aparece un error, no pudimos autenticar su dispositivo Chrome, podría sugerirme si se encuentra con este problema? No puedo hacer andar el dispositivo de Chromecast 

[HMHcdn]

I have CCG2 (basic dongle)and have continued to get the Google slideshow on my (Panasonic)TV  so I know it’s connecting to my home wifi….reset the wifi when it went down on the 9th, unplugged (CC)from HDMI port in tv and back in again…still not able to cast from any streamers (Flix, Prime etc) what should I be doing? For those out there like me that are tech illiterate….thnk u!

[Magot]

I am having same exact problem! Please post if you find a solution. My chrome cast device, 2nd generation type,  is "no longer found or recognized" which it WAS able to do, before March 9th.  THX.

[Betoraf]

Gente, yo lo solucione volviendo un mes a tras el teléfono y lo pude configurar bien, hizo un actualización, después la app Google Home se me colgó un rato así que salí y volví a la app y me lo reconoció, volví la fecha como estaba y ahora lo estoy usando 

[HSchusler]

[Twin2yve]

I did a factor test, it’s still not working. 

[sbharvey374]

Did you follow these steps outlined by user: johnnyzero2

https://www.googlenestcommunity.com/t5/Streaming/Regarding-an-issue-with-Chromecast-2nd-gen-and-Chro

Leave your unit power up on your local Wi-fi network. It takes time for the google server to update the device.

En el día de hoy el chromecast apareció nuevamente en Google Home luego de lo que supongo fue una intervención del fabricante. Yo fui una de las personas que lo restableció con la configuración de fábrica pero luego de eso logré volver a conectarlo a internet.

Si bien puedo transmitir contenido desde mi celular y desde la pc noto que en google home no aparece la opción de configurar el modo ambiente, cuando quiero cambiar las imágenes que se ven por default aparece el mensaje "Solo los miembros con permiso pueden acceder". 

Tampoco funciona con el asistente de google.

He pensado en volver a configurar el chromecast pero tengo temor que luego suceda que no aparezca el dispositivo en google home.

Alguien tiene el mismo inconveniente y sabe como solucionarlo? @Chromecast2, @google

[Laurita2102]

Yo hago todo pero no conecta… desenchufo tal como me indica , instalo de nuevo Google home pero no me conecta dice q no conecta al wifi

[Cente]

RETRASA FECHA AL 7 DE MARZO Y LUEGO REINICIA DESDE CERO TODO

[Laurita2102]

Hola! Sigo intentando poder transmitir desde mi iPhone a la TV con el chromcast segunda generación y en elmultimo

oaso me dice que el chromcast no puede conectar con wifi y todo funciona bien.

que puedo hacer?

I did a factory reset on the Chromecast when the problem started on March 9th and the solution that made it work again was in two steps:
The first step was to remove the Chromecast link from Google Home. Then, I reset the Chromecast again, holding the mini button on the device for about 10 seconds. After that, I changed the date on my smartphone to March 8th, 2025 (one day before the bug). Soon after, I reinstalled Google Home and configured the Chromecast, linking it to the device. After all that, I tried to mirror the phone's screen and confirmed that the Chromecast returned to the same situation right after the bug and before I had reset the device.
The second step, after the configuration was successful, I reset my smartphone to the current date and unplugged the Chromecast from the socket for 10 seconds. I plugged it back in and the Chromecast was automatically updated via the internet and then the mirroring with the smartphone started working again. I hope this helps!

[Laurita2102]

Intenté hacerlo con el iPhone y no pude

[JML23]

Thanks for this! 
It worked for me doing this:
 - I changed my phone date 
- I factory reset the device
- i added the tv on google home via my phone  
- I turned off wifi etc cand changed the date back to correct date 
- i was then able to cast 
Fingers crossed this remains stable!

It work ty

[TrvlrsNinetales]

Hi all, I saw a comment a few days ago about what to do if you factory reset your Chromecast before the update rolled out. I couldn't find it so I thought I would make this post to help others who factory reset their device, it worked for me so hopefully it will work for you.

1 - turn off the automatic date/time on your phone and change the date to March 1st.

2 - plug in Chromecast and wait for the prompt to open the Google Home app.

3 - open Home app and start the setup of the Chromecast.

4 - the Chromecast should connect and start a couple of updates. I had an error on the app but left the Chromecast to update fully on the TV and reopened the app afterwards.

5 - turn on automatic time/date settings. My first cast with Disney+ threw up an error but worked the second try around.

Hope this post helps some 🙂

Hello thank you for the information I didn't realize that my phone was effecting one of my friends Chromecast how does that effect his Chromecast that way

[Kokholmsk]

Thank you for sharing your trip! Now my Chromecast is working again 🥳 

Google Home complaint about the update being to slow, but just be patient. Don't touch anything. It worked like a charm 

[killerfish]

Worked for me, thanks!!

[Herman2]

What a great suggestion. I receives the message that updates would take very long and quit. But even without updates this trick enabled me to reinstall Home and make my Chromecast work again after a factory reset. Many thanks

[Daimytron]

THANK YOU! THANK YOU! THANK YOU!

It really worked. Yeaaah 🤗🤗

[Marias50]

Me ha funcionado perfectamente.

Muchas gracias!!!

[Wwwillow]
