I own more than 8 Google devices and Google if you think I'll not change my services because the investment?

I will get new devices and move with another streaming service system.

This is unacceptable.

[CristinaC37]

Correct! I,m too! 

[CookieHappyCat]

See this post.

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

[miketaylorimage]

Love to know what devices your gonna replace them with

[Gizmo73]

Dear all, since Sunday no connection with Wifi possible, of course we did reset starts numerous times, due to absolutely no messages from Google online, that it might be an issue, which Google started off with not keeping licenses up to date. Friendly telephone customer service agent told me how at least to get the device back on the Google home. But still offline. Maybe it is time to offer other solutions. (Send over a different working device by courier?) … Or how long is it going to take to fix it?

[Petra21]

Some here 

[Johnny94]

How did you get it back on Google home after resetting? 

[Moe_Wnk]

Set the date in your phone back to 8th march manually, then go to the google home app and look for a new device and select your chromecast and follow the steps. It’s not working afterwards but it has WiFi connection again and is on the home app, but offline. Now we all have to wait for a solution, like an update from google.

[Gizmo73]

Got told to set the date back to before 9.March, then it worked, but it is still offline, authentification not possible, cannot connect to wifi.

[Moe_Wnk]

Like I said, they have to fix it. In the home app it’s offline, but it is connected as you can see on the screensaver when you turn it on. So it can get the update bug fix when they start to roll it out.

[Johnny94]

Yeah I tried setting date back with still no change to be able to reinstall on the Google home app. An having the same issue with my Google nest kitchen display also. 

[lostmom9]

Same here

[Maupo]

Ok, thank you for your answer, but, unfortunately I alraedy done the reset. What kind of other problems mah I have for this?

Thank you again

[RominaR]

Yo reestableci de fabrica y pude volver a configurar. Pero no me deja transmitir dice q está desactualizado

[dthomasdigital]

I've been slowly weaning myself of google for a while now, time to accelerate that.

[Cesky]

Buongiorno, improvvisamente la chromecast non comunica più con il telefono.

Ho provato a resettarla e a reinstallare l'applicazione Google Home ma la configurazione non va a buon fine.

L'applicazione durante la ricerca trova il dispositivo chromecast  ma al momento dell'associazione si interrompe (quando sul televisore appaiono i codici).

LEggo che è un problema di molti.

Chiedo aiuto per favore...grazie 

[Paolopsb]

Stesso problema. Ho contattato Google e mi hanno detto ci stanno lavorando e di attendere. Comunque è un problema attenzionato. Speriamo che si sbrighino 🤞

[Francesco68]

Il problema è presente dal 09/03/2025 per la scadenza di certificati, ho aperto tre segnalazioni ma nessuno mi ha mai risposto, comunque il problema riguarda tutte le Chromecast di seconda generazione (in commercio dal 2015).

Anch'io come molti, non avendo informazioni, ho ripristinato la configurazione di fabbrica e mi falliva la riconfigurazione per "impossibile autenticare il dispositivo", se vuoi puoi risolverlo modificando la data del cellulare a una data prima del 09/03, ma ti permette solo di riconfigurare la chromecast, per la visione in streeming permangono le difficoltà. Speriamo risolvano presto .... 

[Mario69]

Mi aggiungo alle vostre segnalazioni, anche a me i messaggi che compaiono sono del tipo "impossibile autenticare il dispositivo chromecast". Speriamo risolvano in fretta 

[amyikin01]

When and how we can be informed when the problem been fixed

Untrusted device Hall TV couldn't be verified. This could be caused by outdated device firmware.

I am not able to connect suddenly. 

[Vamsigurram]

Since few days we are facing issues with Chromecast while setting up the device after Reset, "It is not getting authenticated successfully". I am using this device since 2018, why authentication problem is arising now?. I have reviewed all the recent community posts, many people are facing the similar issues. What google is trying to re-invent with these devices now?

[Stef69]

Toujours le même problème depuis dimanche à 18h. Impossible d'authentifier le chromecast. Cela devient vraiment très pénible. Espérons que Google gère le problème et qu'une solution nous sera apportée dans la journée...

[Philman]

I am having exactly the same problem and Google Help hasn't been able to provide me with a solution. Not happy! 😡

After installing a new router (freebox ultra vs freebox revolution) and resetting Chromecast video gen 2 and follow google help advice's, nothing work, authentication fails ....HELP

[fmassari65]

Stesso problema. Domenica Chromecast ha smesso di funzionare. Dopo tanti tentativi ho fatto il reset di fabbrica e durante la configurazione il codice che compare sulla tv poi non compare sull'app Home sul cellulare e dopo un pò mi da questo errore ("impossibile autenticare dispositivo Chromecast"). Una vergogna!

[sbharvey374]

How long will the 2nd gen product be supported for:  See what Gemini said about this:

Google ended support for the original Chromecast (1st generation) in 2023, but the company has also discontinued production of all Chromecast models, replacing them with the Google TV Streamer, while continuing to provide software and security updates to existing devices

I was prepared to e-waste the thing after it was bricked by whatever your unintended update to google home and or Android OS for my Samsung.   I have a Linux based Server/Router and I was able to tell the device had a valid IP address and Hardware address and appeared to have the requisite ports to work.  The frustration is there is no diagnostic software to verify the kind of issue that caused the issue.  Had I had that I would then been to interrogate the Chromecast and have an error code and/or a message stating the hardware was ok, but the issues was elsewhere.   I could then wait for an update.  As a result of no really meaningful diagnostic SW I reset the Chromecast and went through the Google Home byzantine software on my Android phone connecting directly to (via Chromecast network) only to wait for failure to communicate to the Chomecast.   The Software connects successfully, then after about around several minutes of the silly graphics churning and then "the you lose" message comes up.
