'We couldn't authenticate your Chromecast"

Within last couple days, unable to cast (Netflix). After factory reset the Chromecast, seems all is good. Device found and select to connect. But, keep getting "... couldn't authenticate your Chromecast"

Same here. At sunday Netflix gave an error after trying to connect to Chromecast. Yesterday (monday) I noticed that nothing could connect to Chromecast. Did a reset, now can't get it to work with Google Home due to authentication failure. Tested at friend's place with her wifi to make sure it's not my home network that's at fault, but no good, same error. My guess is that Google pushed an update that broke Chromecast for some people. Question is, how to get it fixed, as in current state my Chromecast cannot access internet for updates.

Chromecast 2

Edit: In case someone's actually reading these I'm doing an edit. Reason wasn't Google breaking Chromecast with update. Things broke because they didn't update - a certificate inside Chromecast expired.

Anche a me da ieri da il seguente errore: "Impossibile autenticare il dispositivo Chromecast. Visita il sito support.google.com/chromecast per ricevere assistenza per la risoluzione del problema. Ok"

Ho provato a resettare la Chromecast, riavviare il cellulare, il router, reinstallare app Google home e il problema rimane sempre. Google fatti viva a darci spiegazioni! Grazie

Chromecast said not to reset to factory settings, if already done so we have to wait until they’ll fixed the issue and then they will advice us what to do 👍

I'm in the same boat. I changed my WiFi and had problem with both chromecasts, but managed to get the bedroom one working fine, tried livingroom again and no good. This was Sunday. Finally thought I'd try a factory reset after waiting for support to phone me back on Sunday and this morning, still waiting, and apparently chat doesn't exist on the link in the app?

Now seeing I shouldn't have done the reset, going by what someone above has said, so that's grand 😏

I had the same issue but if you reset you phone/ipad date to before 9 March, you should be able to set-up chromecast.. but that being said, it is still not connecting to netflix for me

Milo20 — Tue, 11 Mar 2025 13:16:59 GMT

Doing this did work for me to add it back into the home app. But like you I am still unable to cast to it.
