Hi dracarolrocha,

Thanks for posting in the community. I'm sorry you're having trouble casting to your Chromecast. I understand how frustrating that can be, and I'm here to help.

To help us troubleshoot effectively, could you please provide the following information?

What Chromecast model do you have?
What operating system is your phone or tablet running (Android, iOS, etc.)?
What version of the Google Home app are you using?
When you say it "shows images," what exactly do you see on your TV screen? (e.g., Chromecast backdrop, error message)
Is the Chromecast plugged directly into a wall outlet, or is it powered by the TV's USB port?
How far is the Chromecast from your Wi-Fi router?
Are you using the same Google account in the Google Home app that was used to set up the Chromecast?

I look forward to your response so we can get this resolved.

Regards,

Kevin

Chromecast Audio - cannot authenticate

Navrig — Sun, 09 Mar 2025 17:28:44 GMT

I have a Chromecast Audio I have been using for years. It has always been setup in the same place.

We haven't used it as much as we used to but this afternoon I decided I wanted to stream some music. Although Spotify offered it as a device for casting it could not connect (this was from my phone). I tried several times. Spotify on my Chromebook couldn't see the Chromecast Audio.

So I reset the Chromecast Audio - pressing the reset button so the LED cycled white/amber (flashing)/white (steady).

Then I tried to add it to Home using the app on my phone. I get the error shown in the attached sccreenshot.

I have tried 3 times to do this and get the same message each time. The link offered doesn't seem to suggest any solution.

Casting from VLC, Pocket Casts, or SomaFM worked great. But Google Home stopped connecting so no volume control. I reset the device to add it again and I'm getting an error: We couldn't authenticate your Chromecast Audio.

Is this device no longer supported?

Chromecast non trusted anymore

matthieubrucher — Sun, 09 Mar 2025 17:31:04 GMT

Hi,

I just came back home to see that I can't cast to my TV anymore. It was working this morning, but now, my phone says that the ChromeCast (old model) has an untrusted firmware? What is going on Google? Are dropping support again without warning?

Julie_K — Sun, 09 Mar 2025 17:33:39 GMT

I get the same issue with my chromecast mid cast, an i get the same error after resetting and trying to reconnect

Re: Chromecast non trusted anymore

Julie_K — Sun, 09 Mar 2025 17:36:44 GMT

Same happened to me mid cast

Re: Chromecast non trusted anymore

Kurtmieville — Sun, 09 Mar 2025 17:37:18 GMT

Same here.

Re: Chromecast Audio - cannot authenticate

Bob_bob — Sun, 09 Mar 2025 17:37:29 GMT

Have the same problem, yet where is the support on this one?

Re: Trying to re-setup my Chromecast Audio and We couldn't authenticate your Chromecast Audio."

Kurtmieville — Sun, 09 Mar 2025 17:37:59 GMT

Same with my chromecast audio

Re: Chromecast non trusted anymore

Santoshcattavar — Sun, 09 Mar 2025 17:38:12 GMT

Even I am getting this issue. It says could not authenticate.

Gingerphil — Sun, 09 Mar 2025 17:39:27 GMT

Funny, I just started having issues with my Chromecast audio too.

Tried a reset of the device and now cannot add due to some authentication issue.

Re: Chromecast non trusted anymore

JillG — Mon, 10 Mar 2025 16:07:32 GMT

Hi @matthieubrucher and all,

I will escalate this to our Chromecast team.

~~In the meantime please try to restart or reset your Chromecasts.How to factory reset your Chromecast or Google TV Streamer - Android - Streaming Help~~

Can you let us know the device you are using, your region and the Cast firmware version. (Device info, Tech info)

Thanks!

Re: Chromecast Audio - cannot authenticate

Kurtmieville — Sun, 09 Mar 2025 17:41:31 GMT

Same here. It seems they shut down the older Chromecasts around 6 pm CET. Got the same problem all of a sudden on one second generation Chromecast and three Chromecasts audio. Our whole video/audio set up is gone.

Re: Chromecast non trusted anymore

Sandy28 — Sun, 09 Mar 2025 17:42:29 GMT

Também aconteceu o mesmo por aqui

Re: Trying to re-setup my Chromecast Audio and We couldn't authenticate your Chromecast Audio."

Landotter — Sun, 09 Mar 2025 17:42:30 GMT

They may have quietly ended support. Ridiculous.

Re: Chromecast non trusted anymore

Julie_K — Sun, 09 Mar 2025 18:00:46 GMT

I get the same error after reset, that they cant accept the device.

Im in Jutland, Denmark, and i am using Chromecast model NC2-6A5 (i think its a gen 2)

We also have a Chromecast Ultra, which works fine - so it seems to be an older gen problem??

Re: Chromecast non trusted anymore

Carstenk — Sun, 09 Mar 2025 17:46:43 GMT

Same here. Stopped working all of a sudden and refuses to setup even from scratch. "Can't authenticate your Chromecast". What's happening???
