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.

[Kurtmieville]

Same with my chromecast audio

[Landotter]

They may have quietly ended support. Ridiculous.

[Vikingnorse]

Same here.  The entire house is set up to stream to Chromecast audio devices.  Tried resetting and updating Home as well - no luck, and now a reset device that can't authenticate?

Everything has worked fine for YEARS without any changes or adjustments.  Hope is not a push to force people to buy Google speakers as Chromecast Audio was a perfect setup - no need to drop support when it simply works.

[Red_Acrobat]

I am receiving this error on I believe a generation 1 Chromecast...  If they're going to stop supporting a device. I hope that they replace it in some capacity or give us a discount on the next device.

[Tookie]

I’m having the same problem. I restarted the chromecast, my router, updated the app, etc. and now it won’t connect at all. So frustrating! 

[Red_Acrobat]

I'm seeing a lot of this across the board right now.  It looks like my Chromecast audio is also affected.  Fingers crossed, that it's a mistake and they'll push out an update.  My biggest fear is that they stopped supporting all these devices since they stopped making them.

[FnewDevs]

Same here, started this morning with Chromecast could not authenticate if you try to set it up after removing and adding as suggested by previous posts when this happened 2 years ago 

[Landotter]

It looks like this is a certificate glitch and should be fixed but if it isn't fixed I guess I'm just going to go and get a Bluetooth dongle and suffer the slightly less fidelity.

[Neve]

My chromecast has been working for years, and now all of a sudden since around 5pm it stopped working. It keeps saying it can't authenticate 

[Isildork]

Same here

[NerKer]

Same here

[morf]

Same for me. Saw all my chromecast offline. Already done a reset of all chromecast. When I try to add them with google home it says they are untrested devices. Good job google! Please don't update anything..it is worst everytime!

[Oog]

Same here.

[Lilahnz]

Mines just dome the same this morning too

[sammi]

Same for me...useless

[Emma10]

I have the same problem, any possible solution?

[sammi]

A similar problem occurred a few years ago. It recommends reboots of pretty much everything. However, this didn't work for me.

[Eaa2]

Same here.. both devices.  

[EstebanB]

Mismo problema. Espero alguien publique la solución. Ya probé todo

[JGoo]

Me too

[Jonboy22]

Same here 

[DropbearRob]

Same here multiple devices. Except mine aren't gen 1. Mine doesn't say untrusted device. Mine says unable to authenticate device. 

But the result is the same. No working Chromecast. 

[NeilJames]

My Chromecast stopped casting, so I am going through all the ways to try to reconnect it. After unplugging/resetting/rebooting the device, deleting the Home and adding a new one, I am trying to setup the original device, but after Google Home finding and identifying the Chromecast, it fails repeatedly with the above message being displayed.  It is a 3rd gen model (without the remote). 

Has anyone discovered a fix for this? I did call Google support, but the call was disconnected due to a poor signal.

Any advice gratefully received,

Neil

[Hds]

The same 😤

[Mama1422]

Same for me 😬 no solution! 

[Binkie123]

And another one...

[Kellyk44444]

Pareil ... 

[XiaoC]

Same here, I have 2 and both are doing same

[GRUNDDAL68]

I am experiencing the exact same problems rigtig now

[BarbaraNunes]

Estamos extamente com o mesmo problema. O nosso é cde 2° geração, será que desatualizou?

[Imai]

Same here. Try everything. So frustrating.

[Laila15]

Same problem

[Bhorta]

Same here, with two 2nd gen  😢

[Kat1919]

Ok I have the same issue currently. Good to know it's not just mine. 

[j_aires12]

Mesma coisa aqui. De repente parou de transmitir e nao conecta mais aparecendo a mesma mensagem 

[Elenapanema]

I have the same problem right now 

[GhulamGGL]

Same Problem 

[Hds]

Hope that they don't stop support the Chromecast Service without telling....🙄

[MattQ]

Same.  I was literally using my Chromecast Audio this morning to stream Spotify.
It looks like someone in the datacenter finally pulled the plug on Chromecast.  I know they ended the product in 2019 and said they'd keep releasing updates until September 2025 but it looks like a TLS security certificate on the device finally expired or something and they didn't update it to a new one.  Now we all throw them away because Google won't allow us to transition it to the OpenSource community and maintain it ourselves. What a waste.
