I've already done a factory update and removed the device and now it won't let me add it back ... help 

[Yve]

The fault is on their end, not yours.  They appear to be in no rush to fix it and certainly no hurry to keep their customers updated

[ccouto]

it is worst, they redirected us to an empty room, we are not talking to google but to each other,

[Raeberry]

I hope this doesn't take as long to fix as the ambient clock size did!  Watching TV on my phone is  such a pain in the  hind-end.

Getting a new casting device from another company to use on my not-smart TV is not an option for me right now. Even if I could afford it, I'm opposed to the mindset of a disposable society. Upgrades and new technology are wonderful, but I'm stubborn enough to see most things through and find fixes even with hard work. Reuse and recycle is a hill worth defending. And I used to think the "don't-be-evil" company's values aligned with that. I'm losing faith with you, Google. You used to do better, try harder.

Should I regret becoming aligned with y'all when I accepted your invitation to Gmail all those many years ago? 

Me and my bad eyes eyes just wanna watch my shows TV big, not phone small. Fix this with expediency, please. I'm getting super cranky.  Giddyap!

[ccouto]

you are not talking to google, they redirected you to an empty room

[MayoDagreat]

How will I know when it's fixed?

[Sophymills]

Do we have an update yet? I use my Chromecast to watch everything and it's basically a brick right now. 

[Xtradeep]

This is what will happen. Support for older chrome casts has ended so now they break them to force us to buy the new ones. No bloody likely. It was good when it worked but only when it actually worked.

I'm sick of waiting and pulled the bustard thing out. Im using my.laptop and a hdmi cable to tje TV. Works well,nowhere near as buggy as a chromecast amd now free from that control.

Also have a usb c to hdmi adaptor for my phone so tjats fixed as well. Screw your chromecast.

[Geen1]

HI Xtradeepm Please explain how to do this? 

[ccouto]

you have to buy an adapter USB-C  to Hdmi  

[Geen1]

ok, thanks, and what about usb? Can you please explain the steps?

[JuanGarrido]

Me suena raro lo de no restaurar ha estado de fábrica, es una reacción normal cuando algo deja de funcionar.

No se que pensar..... 

[Joni0627]

Lo reinicie desde el primer día que tuve el problema, pensando que era algo local, que va a pasar si lo reinicie??? Cuando va a estar solucionado? Es alguna estrategia para cambiar de modelo?

[Dddde]

What should I do if I had already reset it?? Any support pls!! 

[DmitryBo]

How to make sure I'll get an update from Google when issue is fixed? I factory reseted my device two days ago and can't set it up again.

[ccouto]

contact google nest support 

[Adolfopatarroyo]

I already did factory reset, it was my first way to try to fixed. So what now?

[DanVR]

Google, you had a good run but it's time for me to try other services. The way you are handling this is a good example for me to move on. 

"My mill grinds pepper and spice, your mill grinds rats and mice"

[ccouto]

this is an empty room, nobody from google is here

[jnorris854]

Has there been any further update from yesterday? I reset my chromecast thinking it was an issue with my chromecast. I have been unable to steam for 3 days now and when I try to set up the chromecast it will connect to the internet. Followed by this error: TV may be set up but we could not communicate with it from your iPhone. Make sure that you have enabled network access in your iPhone's privacy settings. Then try again. The settings are all enabled and am getting this error across 5 different devices including phones and ipads. How do we fix this?

[ccouto]

wait google fix it on their side

[envagyokajoe]

So we should have search the Internet first before trying some common sense bugfix steps like a factory reset?

[Sticky67]

There was no reason to stop selling the audiocast in the first place and the reason must have been purely for an alternate Revenue stream that wasn't disclosed. I love and I have 6 of these in my home.  Hope this doesnt come down to a class action.

[jnorris854]

he internet was working for everything else so it is definitely a chromecast issue

[Pipertstar]

Estoy encontrandome con que todo el mundo esta teniendo problemas... cuando se soluciona esto... Necesito poder seguir utilizando mi chromecast sres, no tengo dinero para comprar otro.-

[ccouto]

tiene que esperar unos dias

[LWhisper]

Let me help Google engineers solve their problem quickly:

func AuthenticateDevice(req Request) bool {
    log.Println("WARNING: Temporary solution for device authentication due to internal issue")
    return true
}

Seriously, guys, let us use the devices we bought normally. Add an offline mode to your apps that will work with any device without any authentication. 

[DrDoomToo]

Still waiting for the correction for my Chromecast Audio.

[TamaraBriosso]

Hola veo que a todos no nos funciona el chromcast? Ya queda obsoleto?? No hay más solución?? Ya no se en donde pedir ayuda para que se solucione!! Si ya no sirve más por lo menos que avisen 

[JamesPFitz]

Wellllll?  We're WWWWWWAAAAIIIITTTIIIINNNGGGGG.

[Bluegum]

Very frustrating, it's been going on way too long! Tried to change the date on the phone but that didn't work, it keeps showing that I'm offline. Wonder how long this is going to take?? we just subscribed to a new streaming company...

[AlexM1989]

I have two Chromecasts (second generation). Suddenly, both Chromecasts stopped working (they are offline). I reset one device and reconnected it using the Google Home app. Everything worked fine until the Wi-Fi connection step, but unfortunately, the connection to the Wi-Fi failed. What can I do?

My Chromecast stopped working two days ago and now when I try to reconnect it says that my device cant authenticate my Chromecast. I've rebooted and reset everything but still no connection, can someone please let me know when this issue will be fixed.

[JuanGarrido]

A mi me pasa igual. Hablan de un problema en los antiguos equipos. 

Entiendo que serán rumores

[ccouto]

in the future

[KoB_2025]

Still waiting for how to get my 2nd generation Chromecast to work after the factory reset. Any news?

[Josh_790814]

My Chromecast stopped working two days ago and now when I try to reconnect it says that my device cant authenticate my Chromecast. I've rebooted and reset everything but still no connection, can someone please let me know when this issue will be fixe...

[Tayz24]

Exactly the same issue here. Mine has been working fine, I went away for the weekend and now it won't connect or authenticate my Chromecast. I've removed it from the home app and rebooted it, unplugged it for a few mins and tried reinstalling but I have the same error message. 

[Ewfer77]

Me acabo de dar cuenta y tengo el mismo problema incluso intenté lo mismo pero no da más que que "ocurrio un error al momento de autentificar"
