I have same issue also

[Autentication]

Same problem, my chromecast doesn't work since yesterday. I have reseted to factory values, but now it doesn't abe to autenticate.

[wicara]

The only way to get it connected again is to roll the date back on your phone to January and connect and set up the device. This will get it connected to the internet the rest is up to Google getting a fix. Remember to fix your date as nothing else will work until you do.

Today is Wednesday and still no fix.......

A good idea is to inform your user base about progress of the fix ....

[Pirses]

Despues de 3 dias los que reiniciamos seguimos sin soluciones.

[Y2]

How are we on day 3 without a fix globally?

[Rubio09lrs]

[BadFlash]

They didn’t even dare understand the issue .  It’s just the CC internal SSL certificate that expired .  That article is pure BS!

[JSFEcho]

Nothing is working. I cannot cast to any of my devices of which I have about 30. Doesn't matter how old they are. I can view the camera on my nest Max home hub, but I cannot control anything else on it. It won't even let me look at the settings. Same goes for all my other devices. Chromecast audios speakers Google homes nest homes so on and so forth. Nothing works. Unfortunately this happens all too often.

I reset the chromecast 2 nd generation... what can i do to configure again? I want a reply

[Dander2]

Sigo sin poder configurar el Chromecast. Desde el domingo 09/03/2025 que no me funciona (en 7 años jamás dejó de funcionar)
Acabo de actualizar la app Google Home a la version 3.30.1.5 y aún no me permite configurar el dispositivo.

Aguardo respuesta

Hello, I also restored it to factory settings and following the following steps I was able to reconfigure it, I managed to broadcast from the mobile to the TV again, but the image from the mobile is only partially displayed, at least I was able to reconfigure it and now I just have to wait for the update.

First of all, you need to change the date on your mobile phone to a day before March 9, 2025. From here you can reconfigure the Chromecast.

Then follow the following steps to be able to broadcast again

Fix casting from Android (GUI method)

• Download and install an activity manager app, like the free and open-source Activity Manager app.
• Launch the app and select Intent Launcher from the dropdown menu in the upper right corner.
• Tap the edit icon next to the Action field and type/paste this: com.google.android.gms.cast.settings.CastSettingsCollapsingDebugAction
  • On Android 11 and below, type/paste this instead: com.google.android.gms.cast.settings.CastSettingsDebugAction
• Leave the other fields blank, and tap the checkmark button in the lower right corner.
• In the Cast Debug settings panel that pops up, scroll down to Connection and enable Bypass Device Auth.

This workaround forces open the Cast Debug settings page and lets you enable the Bypass Device Auth option (i.e., it allows you to turn off device authentication), partially fixing the issue. You should now be able to cast from apps, and the Google Home app should also partially work.

Hola, yo tengo exactamente el mismo problema. De pronto dejo de funcionar y ahora no puedo volver a configurarlo.

[Jawii]

Lo mismo me pasa a mí. No se puede autentificar el Chromecast.ya sin muchos días esperando para una solución .

[rajatvyom]

Unfortunately reset was done already beacuse most of time only that work , issue started with not able to cast due to outdated firmware warning not its gettimg setup and says cant communicate to chromecast

[Rhawk51]

[line-johannesen]

[Stef69]

Pareil pour moi depuis dimanche à 18h...

[Nanar]

Same here since a couple of days...

[Zyra]

Same here! What is happening?

[CookieHappyCat]

See this post.

It's not the final solution, but it might help you 

[Camelot1]

Same here for the past 2days

[Mariola21a]

Will that be fix at all? I spent 3 days and 2 phones (android and iPhone) and tones of different apps to figure out what's going on. You should have better way of letting ppl know that problem is on your side. Had no clue about this website. Waisted 3 days and now know one can give us an ultimate time when problem will be resolved.
