Col vostro messaggio Ho notato che è stato rilasciato un aggiornamento di Google Home ho creduto per un attimo che avesse risolto la situazione ma purtroppo pur identificando il dispositivo Chromecast ancora non riesce a connettersi 😭

[Cieleia]

Há alguma previsão de quando haverá essa correção?

[rcdude7378]

Bring back Chromecast Audio!!!

[Ryno]

Thank you.I missed my device very much.Please work diligently to fix the problem.

[Iamerin]

Have already tried to  factory reset device. Will you send through troubleshoot details please?
Thanks

[Zidac34]

How will we get the answer?

[Chrisbear]

Hopefully on this forum page, bookmark it 🙂

[PietroDietro]

2 days (and counting) seems like a really long time to diagnose and fix and expired certificate issue!??

[Shessoofancy]

Been off for like a week, I thought it was my actual unit, swapped to another one (I have 4) and that was was fine. So idk what’s up 

[Nvga]

Qual a previsão pra resolver isso? 

[Brettmura]

Any timeline on the repair

[rcdude7378]

 You had me digging out this old usb-c to mini Jack adapter I think I got with my pixel 1.

[Emusk]

Just jacking it noice

[Richard-J]

As you should be aware, your own trouble shooting procedure says to factory reset.  You need to accept responsibility for your poor quality trouble shooting procedures and fix this issue.

[Betoraf]

Agradezco que se preocupen y ocupen como corresponde, pero Mi Paciencia y la de casi todo el Mundo se va a terminar pronto, en especial la mía y eso que soy una persona muyyy paciente, den una pronta fecha de solución o acepten que no la hay, nosotros veremos y nos organizamos para ver qué fin va a tener todo esto, saludos 

[Nourothman]

When should we expect a fix?

[Fletch64]

First I got "Untrusted device" with no solution. I did a factory reset and not can't connect at all. 

[lilianamartini]

Por favor mantengan al tanto de las novedades. He reseteado a fábrica el Chromecast y actualmente no tengo forma de configurarlo por no poder conectarme al dispositivo.

[jshawsworld]

Still not fixed?

[Adolfopatarroyo]

They should have told us this 2 days before because it's already a bit late.(Please do not factory reset your device)

[Betoraf]

I appreciate your concern and attention as it deserves, but my patience and that of almost everyone is running out, but mine worries me and I am a very patient person, give a quick solution or accept that there is none, we will organize and see what end we give to all this, this is translated with your translator and I hope you understand it, the next message will be in Chinese, Japanese, Arameo and so on until you understand it, greetings

[Betoraf]

我感谢你的关心和关注，这是应得的，但我的耐心和几乎所有人的耐心都快用完了，但我的耐心让我很担心，我是一个非常有耐心的人，给出一个快速的解决方案或接受没有解决方案，我们会组织起来，看看我们能给这一切带来什么结果，这是用你的翻译翻译的，我希望你能理解，下一条消息将以中文、日语、阿拉姆语等形式出现，直到你理解为止，问候

[Pablozky]

¿Existe alguna novedad o tiempo estimado de solución? Si ya indicaron que encontraron el problema, luego de 2 dias sin poder utilizar el dispositivo, el cual en mi caso poseo 2 Chromecast de Segunda Generación que estan inoperativo, deben indicar al menos un tiempo estimado de solución al ya conocer el problema y su complejidad.

PD: En la app Google Home almacenan los dispositivos vinculados en cada cuenta Google, donde se detalla la información de los dispositivos. Podrían implementar un sistema de notificaciones en la misma App que nos indique este tipo de problema o que nos redirija a esta web, ya que no es correcto que los usuarios se enteren de esta incidencia a traves de otros usuarios y no directamente de Google.

[Betoraf]

J'apprécie votre sollicitude et votre attention comme elle le mérite, mais ma patience et celle de presque tout le monde s'épuise, mais la mienne m'inquiète et je suis une personne très patiente, donnez une solution rapide ou acceptez qu'il n'y en ait pas, nous nous organiserons et verrons quelle fin nous donnons à tout cela, ceci est traduit avec votre traducteur et j'espère que vous le comprenez, le prochain message sera en chinois, japonais, araméen et ainsi de suite jusqu'à ce que vous le compreniez, salutations

[nachobkcc]

Google already showed their customers how inoperative they can get when support is needed. So, why will you people keep waiting for an official solution.
A developer already came up with a fix (reddit).
I don't know if I can share the link here, but you can always google it. I just followed instructions and got it working.

[johnnyzero2]

Yes, the Reddit fix you're referring to (actually a clever workaround) will restore Gen2 casting for Android devices & Chrome browser. Worked for me. It's not perfect, but it will suffice until Google issues a proper security certificate fix.

Here's the link:

[brookwithnoe]

Unfortunately, this did not work for me

Workarounds

Although it's on Google to fix this issue properly, I've found a few workarounds that might get you up and running again, depending on the device you're trying to cast from. Note that I'm editing this comment frequently to refine the instructions and add new ones.

Fix casting from Android (GUI method)

1. Download and install this Activity Manager app. I am not affiliated with it, but it's open source and seems to work as advertised. Note that you can download an APK directly from that page—you don't need to install F-Droid if you don't want to.
2. Launch the app and select "Intent launcher" from the dropdown in the upper right.
3. Tap the edit icon next to "Action" and paste in com.google.android.gms.cast.settings.CastSettingsCollapsingDebugAction. Leave all other fields blank. On Android 11 and below, use CastSettingsDebugAction instead of CastSettingsCollapsingDebugAction.
4. Tap the checkmark in the lower right.
5. In the settings panel that pops up, scroll down to "Connection" and enable "Bypass Device Auth".

This should fix casting from apps and partially fix the Google Home app. (It now shows me the Chromecast's status, but things like changing the name still don't work.)

Fix casting from Android (ADB method)

1. Connect to your sender device (the phone or tablet you're casting from) using ADB.

2. Run the following:

   adb shell am start-activity -a com.google.android.gms.cast.settings.CastSettingsCollapsingDebugAction

   On Android 11 and below, use CastSettingsDebugAction instead of CastSettingsCollapsingDebugAction.

3. In the settings panel that pops up, scroll down to "Connection" and enable "Bypass Device Auth".

As above, this should fix casting but not necessarily the Google Home app.

Fix casting from Chrome and other Chrome-derived browsers

1. Download this file (which is just the CAs that have expired in PEM format), or copy the text into Notepad and save it as chromecast-ica-3-4.pem. [UPDATED March 11th to also include the Chromecast Audio intermediate. I changed the name from chromecast-ica-3.pem to indicate the difference. Big thanks to /u/meatbox for getting a copy of the Audio cert.]
2. Launch Chrome with the command-line switch --cast-developer-certificate-path=chromecast-ica-3-4.pem by following the instructions for your OS here. On Windows, you might need to pass the full path to the downloaded file instead of just chromecast-ica-3-4.pem. (Thanks, /u/yossarian_vive!) For more detailed Windows instructions, see /u/FreeSpeech90's excellent reply.

Note that, while running with that switch, Chrome will show a notification stating "You are using an unsupported command-line flag". Seeing that is a good sign, but it doesn't necessarily mean you've specified the path properly. If casting still doesn't work, double-check the path and file name.

This adds the expired certificate as a root of trust, which bypasses expiration date checks.

i cant find "Intent launcher" in appen kun "IntentResolver", need help!

[nachobkcc]

You'll Finde "Intent luncher" inside "activity manager app", an app inside f-droid
