[Marinasdotter]

[Rocket67]

[xerox97]

Samething happened to me. But only one of my chromecast device is not being recognized. However it is an older version. 

[Bdmack]

[xerox97]

[xerox97]

[SharnNZ]

When will Google tell us what the problem is? It’s been over 6 hours now!

[edward8]

Yes, Chromecast audio stopped working today. I did factory reset but haven't been able to get it working again using Google Home app.

[DirtyBiker]

My Chromecast failed to connect today was still connecting to the internet but could not cast anything to it so I went through the factory reset and now the home app sees it but cannot connect to it what gives Google

[Rocket67]

Exact same issue as me...

[Djb200]

Same at 3:20 am for last hour. Tried resetting Chromecast for both Android and iPad. Wasted so much time. Finally found this community so.it appears to be a failure across the board. (Black disc model).

[Greg19]

Même problème pour moi depuis hier sur chromecast audio et vidéo 2nd gen. Rien à faire j'ai tout essayé et la demande au support reste en attente

[MowokS]

I'm glad to see I'm not alone with this problem.

3 devices are unvailable to cast: 2 audio and 1 video dongles.

I tried to reset the video one but the process to reconfig fails.

I have no clue to solve that.

[Jaybalanced]

Shed TV may be set up, but we could not communicate with it from your iPad. Make sure that you have enabled local network access in your iPad’s privacy settings. Then try again. What is this for? I’ve reset everything 

[Teltel]

Chromecast not working anymore just working yesterday anf now cannot cast anymore

[Jo98]

Same 

[Malenacagnani]

No funciona mi cromecast me pide Dispositivo no confiable No se pudo verificar Dormitorio. Esto puede deberse a que el firmware del dispositivo está desactualizado. Y no pasa nada

[Campusma]

Me está pasando exactamente igual, parece ser que es un problema masivo

[Danyk69]

Estamos igual dejo de funcionar de golpe

[Teltel]

Any guide how to work the chromecast today is not working anymore cannot even find the device even we go to home apps..

And cannot even update the device coz it is no longer searchable

[Ange177]

bump, same issue

[Geoffrey07]

You are not alone, same here in the Philippines

[Rbees]

My Chromecast 2nd (or maybe 3rd generation) is not working since last few hours. I am not able to cast content from my smartphone to TV. I tried all the possible solutions given in Google support (troubleshooting) to connect it but nothing happened . 'Google Home App' is not reflecting my device title... I came to know from Reddit and other social sites that many users are facing the same problem since last many hours. Why is this happening? When will Google fix this?

[BaronSengir]

Chromecast 2gen stopped working due to a certificate error .. I tried my spare one but got the same error ... Reserved bout of them and now they can't be installed in Google home .. it connects to them but times out during installation after connecting to them...  And why do o fins out there is a problem on Reddit and trending searches on Google ... Instead from Google ... 

[Elinalis]

Mis chromecast no funcionan desde ayer. Desinstale la aplicacion de google home para reinstalarla pensanfo que asi lo solucionaba y ahira ni siquiera puedo instalarla nuevamente.

[EkuP]

Por lo que leo es un problema a nivel mundial. Ojalá lo solucionen pronto!

Have 2nd gen w/  275994 firmware, 24 Feb 25. In device info (that I can no longer access but screen capped) my Home is dimmed out/no permission. Says I have preview program (but shouldn't-do believe I opt out of everything) I didn't get the chance to click on everything else, because I was busy doing all of the resets/factory reset/reset router/hard phone reboot/uninstall-reinstall Home-so that, I am now stuck at the point of it telling me I cannot connect (strangely one time I was able to see notation that I needed to be connected to the same WiFi as my mobile device-however it clearly shows that both are connected to the same-however the CC will not complete the reconnect. It worked fine throughout the day. It is, however, as though I do not have 'control' or permission on my CC device however. BUT am the only one in the 'home' and the only Admin. I'd replied to a Diamond contact, can't remember where in this place, so am doing a stand alone post. I DID try to write down everything, and did get that screen cap-because I think that holds an answer. AI glitch or coding bug? It can't be from the update after this long of time, imo. I see this is not a locality issue, so am trying to provide as much info as I can, to maybe help this along. 

[DarkJedi]

Any idea when Google will fix the problem with the certificate for gen2 Chromecast users ? It's been down for 12 hours already. 

[Fgyhgffreddyyuh]

I get an error code S S C R-

S 4 0 1 0-2 2 0 3 -

2280-G 

[mrsilvis]

Chromcast won't connect, worked fine this morning. Tried a factory reset and now I'm getting a "cannot authenticate" error message. Fix it google. And if you killed the 2nd gen I'm taking my business elsewhere and not buying your next product 

[Anand2]

My Chromecast also having authentication problems.

[Genec67]

Same here

[Olimed73]

[Trysnail]

Wow me too . What’s the dwal

[Danishmadara]
