C'è un problema generalizzato con i Chromecast e lo stanno sistemando, le indicazioni di Google sono di non resettare il device ma che provvederanno a dare le indicazioni per il ripristino anche per chi avesse resettato. Al momento non si sa ancora niente

[Vangelis678]

When are you going to fix this??? It's been almost a week....very poor customer experience... especially from a company like google!!!

[graciela1973]

No funciona, y como a muchos nos paso, el lunes lo resetee a fabrica.   Nos va a servir cuando solucionen el problema? 

[Ivanespichan]

ya lo reinicie y ahora que perdi mi dispositivo

[Elias_91]

Ya van casi 3 días sin funcionar los Chromecast, cuánto van a tarde en solucionarlo? Si querían que actualicemos a dispositivos mas nuevos hubiesen avisado con tiempo que los volverían obsoletos.

[Giorgia23]

Buongiorno ho collegato chromcast alla televisione, procedo con l’app e al momento della connessione mi dice che è collegato e poi che si è verificato un errore perché nella privacy del mio telefono non ho attiva “ la rete locale” quando invece è fleggata. Mi potreste aiutare? 
grazie

Ciao, anch'io come molti da domenica non riesco più a collegare il mio chromecast, prima di comprare uno nuovo vorrei aspettare per vedere se c'è una soluzione. 

[Fcancel]

Lo stesso anch'io, scoprire a posteriori che non bisognava fare reset ad impostazioni di fabbrica non è bello

[Ckirkham1]

The certification key that expired did not expire on earlier models. 

Unless you fix this problem very soon a lot of people are going to walk away from Google in any form certainly for casting people are going to buy a fire stick from your competitor.

[Jayneslilgirl]

Ive just got in from Currys and done just that

[Jayneslilgirl]

Too late. Only way to view anything here is streaming through my Chromecasts around the house. I was going to upgrade them but not now. Tired of paying for the different platforms but being unable to watch anything... so just got in from buying Firesticks 

[Sprint46]

Hola, el Chromecast no funciona, es imposible de autenticar con la aplicación.

Que demonios está pasando?

Por qué no está solucionado ya el problema?

Esto es ridículo.

[Nanohananoha]

iPhoneもAndroidからもですが、突然TVで動画などが見れなくなりました。　　クロムキャストもWi-FiもiPhoneもアプリも全て全て正常です。再起動したり手を尽くしていますが　何故か信号がキャッチ出来ないとエラーが出て接続出来なくなりました。お手上げです。疲れてしまい　どーする事もできません。🆘下さい！

[Sebshs]

Have you Chromecast 2? If yes, see thread

[Ykiki123890]

何か障害が起きてるみたいですね。私も今週からいきなり見れなくなりました。初期化とかもしちゃったんですよね…見れるようになるのでしょうか。

[Nanohananoha]

コメントありがとうございます。

電源を入れ直したり  初期化、アプリの再ダウンロード  様々な方法を試したのですが改善されないので困ってまして…

[Listo23y]

Lo reinicie rápidamente y no va luego me entero que no había que reiniciarlo ,que pasara ahora

I am trying to connect my Chromecast device, but I get the following message. What could it mean?

"Device authentication for your Chromecast was not successful'

[Christyg42]

I'm having the same problem with my chromecasts hurry up google and fix it 

[Bishoppine]

Same problem.  Apparently Chromecast firmware included an expriation date of 9 March 2025.  Any fix out there?  Thanks.

[Oggyoggy]

Change dáte your phone 2024

This is not a fix for the streaming Issue. It is online suitable to reconnect to your WLAN in case you made a reset.

Hallo zusammen, 

seit dem letzten Wochenende funktioniert unser Cromecast nicht mehr.

Wir haben ein älteres Fernsehmodell und der Cromecast ist die einzige Möglichkeit bei uns zu streamen. Wir lange wird es denn dauern, bis Google das Problem behoben hat? Denn wir bezahlen ja derzeit monatlich Amazon Prime und Disney+ und können beides nicht nutzen.

[Ashamed]

du wirst hier keine ante bekommen. Google hält sich komplett bedeckt, weil sie genau wissen, was der Fehler ist und weil es immens schwer ist, da die meisten Nutzer ihr Gerät schon auf die Werkseinstellungen zurück gesetzt haben.  Davon wird jetzt aber ja abgeraten, obwohl auf der Hilfsseite ja nachwievor dies als erster Schritt empfohlen wird, wenn ein Problem besteht. Ein Nutzer auf Reddit, der sehr viel Zeit und Engagement in die Sache steckt und verschiedene Anleitungen zur Problembehebung gibt, schreibt als Zeitspanne auf jeden Fall von einer Woche. Alle findet man auf deutsch eigentlich gar keine Hilfe, schon gar nicht von Google 

[Ashamed]

verstell mal dein Datum in die Vergangenheit, also vor Sonntag und versuche ob Home dein Gerät erkennt. So ist es zumindest wieder in deinem Wlan und wird erkannt und gibt die Meldung wegen der Firmware an. Streamen geht aber trotzdem nicht. Das Gerät ist aber immerhin wieder "vorhanden". Datum wieder aktualisieren nicht vergessen

[Mira2]

I try to recounting the chromecast put I can’t and received this message 

Mira TV may be set up, but we could not communicate with it from your iPhone. Make sure that you have enabled local network access in your iPhone’s privacy settings. Then try again.

Please solve this issue 

thank you

[MPL-Consulting]

I’ve already done a factory reset bevor I read this. Can you please help me?
🫶🙏

[Shabby]

Same here, I have removed it from home 😞 I thought it would be easily setup as usual.  I've been using it for many years.   But this time. I can't authenticate to set it up.  Let me know if you find any answers to fix it back up

[BasilBox]

It’s currently not working because a recent update or something 

[CookieHappyCat]

Follow my post, it's working @CookieHappyCat

I'm sure I'm not the only one but after years of using the Chromecast dongle, the first we always do when it quits working is reset it to factory and it usually fixes it... so, to tell us not to do it 2 or 3 days after the fact, well, it's a waste of breath.  I've already started looking for replacements TV boxes... one's on the way and we will replace the other as soon as we that it works. This was a huge let down from Google.
