[Emijo]

Same issue from Sweden 

[sammi]

Im in Sweden as well

[Kurtmieville]

I think they know that by now. To me it seems as if a certificate has run out. The question is whether they feel like renewing it for our ancient devices.

[CaptSternn]

That would be not cool. If they did that

I could not cast at all... In home my Chromecast was offline but it was not! Tried to restart but still did not work... So I reset it and tries to set it up again, now I can not set it up! Either Google Home says it can not connect to it.. or that it fails authentication.... What is going on? This has never happened before...is my Chromecast bricked for some reason? 

[Jotaka]

I am having the same problem, never happened before.... No streaming platform was able to send and after factory reset it can't be set up

[Amitavac]

Same problem here 

[Brunella]

Stesso problema dallitalia

[Paul__C]

Same here. Not sure why Google can't be bothered to put a message up when you use their search engine - looks like nobody's Chromecast is working, anywhere in the world. I've wasted at least an hour doing factory resets, uninstalling and reinstalling Home, trying different devices, turning the WiFi router off, only to find that it's not just me.

[Amitavac]

Till yesterday it was working fine. Today morning it worked fine and suddenly it’s not working. Don’t know why. Horrible. Not able to reach out to customer care. It’s getting disconnected 

[MutzNutz]

What the f*:k

[Kloudkj]

Apparently this affects Chromecast audio and Generation 2 devices. Worked this morning then stropped.

No se puede autenticar el Chromecast

Desde el día de ayer el dispositivo estaba sin reconocer para transmitir, lo reinicié y se me borró de la aplicación de Home y ahora intento configurarla nuevamente el dispositivo y me dice que no se puede autenticar el Chromecast

[Victoringo]

Me pasa lo mismo y no encuentro la solucion 

[Tarteaga]

Me pasó lo mismo. Ya Google avisó que está trabajando en la solución. Al parecer venció el certificado original, que tenía por 10 años y deben renovarlo. Ojalá lo.areglen pronto!!! 

[Fra66]

Da ieri sera Chromecast non si collega più e non di riesce più a configurare,home trova il dispositivo ma non riesce ad autenticarlo.
