If Google remove support for this product I will remove all google products I have.  I have Google Pixel Pro 8 Mobile through work that I can replace in a few Months with an apple product.

[Sirmichu]

Are you kidding me? You just bricked milions of hardwares? 

[Chu1eta]

El ChomeCast Audio Modelo RUX-j42 no se puede conectar a la aplicación Home dice que hay un error de validación. Por lo tanto dejo de funcionar. Por favor me pueden pasar la solución. Gracias

Google cromcast not working eror untrusted device issu

[Dsnsyjpeg]

I factory reset mine before I got into this post, I thought I'm doomed for resetting it with that message. Hopefully it would be fix soon 

[deliasw]

It's taking long to fix this issue.

[ShadowWolfOne]

While I appreciate the "update", this situation is extremely aggravating. I depend on my Chromecast to cast programs to my TV everyday,  and I pay quite a bit of money in subscription costs to have access to those programs and it isn't enjoyable or practical to watch them on my tablet. Come on guys...you're telling us you don't have enough technical staffing or cumulative brainpower to have gotten these fixes figured out already?! Please get on with it! These devices aren't just a nicely...many of us depend on them and expect them to work, and if they have an issue, that the manufacturer gets the fixes figured out in a timely manner and out to us ASAP, not DAYS LATER. Until you do, it is screwing up my days and is not doing my opinion of your company any good, either. Work the issue!

[Ryno]

Please work diligently to fix the device.It's a great device.I never wanna give it up.

[RiziaBR]

Também já formatei o chromecast,  seguindo os passos da resolução de problemas.  Tem data pra concluir? 

[Scarpace]

Why does every Chromecast I buy stop working after a few years?

[johnnyzero2]

Wah. First World problems are tough.

[Ihateithere]

I wouldn't be on this page if I hadn't done a factory reset. Would have been nice to know before 

[mcroyle130]

Are you any closer to a fix? I’m about to buy a Roku at this point.

[AnnoyedwithGoog]

Same issue on first gen Chromecast 

[DWasbotten]

Is this a problem with Google Chromecast? Because my error message says my TV is not trusted because of firmware.

[Martin721]

Wonder if you will compensate people for this??? Guess not. Im depending on this to stream tv. Ive paid for this, but yeah not able to do so... you should be by law obligated to compensate people. That would also ensure you gave far better information and updates, plus fix it.

Finally why does your AI gemini advice people to purchase a newer cc, and saying it might not come up and work again??

[ominnp]

Already factory reset done during troubleshooting 

[HauntedinNY]

Too late as many people have already done that but I'm sure you know that. Sadly this is likely going to be an expensive business loss for you as many people including myself will go out and purchase something else. In today's technology one would think this wouldn't take days to correct. I love Google but this is hard to be patient for.

[OneandOnly2025]

To late, i had reset x 2 and got my other one and tried everything to fix and it kept saying not communicating with my phone and to check my phone settings. Even rebooted router. If there was any form of warning or communication from google, I wouldn't have done anything. We've been down since Sunday Australian time! Pls fix this chrome cast situation. We need the streaming device.   🤯🧘🏻‍♀️

[Jo34]

How long to this is sorted I’ve got 3 tvs and none are working it’s taking ages 

[DeborahP]

When can we expect this issue to be resolved, olease?

[twisterarg78]

Creo que Google vendió muchísimos millones de Chromecast de 1 y 2 Generación seria lo correcto darle una solución lo antes posible porque somos millones de usuario sin poder usarlo y avisaron tarde del Factory Reset, son días y se dieron cuenta hoy!, queremos una solución, Gracias con el soporte adecuado.

[Sir_McSquish]

It figures that I haven't used the v2 device in the last couple of years having upgraded to the 4k version on my other TVs... But when I decide today to set up a little exercise corner in the basement and dust off an old tv to connect the Chromecast this happens lol. Already factory reset it because why wouldn't I. Will wait and see I guess. 

[Jelly2]

lol I already did a factory reset because that's all I could find in the official support website, might want to update that. I only found this thread when I was searching for other brands to switch to as a Chromecast alternative

[Magot]

Yes, MARCH 9, ALL of US on this forum...SAY CASTING STOPPED FUNCTIONING PROPERLY!? AN UPDATE- TIME SENSITIVE REQUIRED ISSUE?

HELP!

[BethBlmt]

I have a 2nd Generation Chromecast. Serial #5830103YAFWV.  It is not working.  At all.

[Emusk]

You have the lucky serial number congrats 🎉 report to your nearest dealership for a free Tesla 

[Pamela1975]

since march 9th my chromecast stop working. I’ve tried everything, restart my router, my phone, my google home but nothing works.

Desde el día 9 de marzo pasado mi chromecast dejó de transmitir contenido, reinicié mi router wifi, cambié de TV y al final reinicié el equipo a modo fábrica, nada funciona

[Arias]

Desde el día 9 de marzo pasado mi chromecast dejó de transmitir contenido, reinicié mi router wifi, cambié de TV y al final reinicié el equipo a modo fábrica, al intentar configurarlo me aparece un error de autenticación del chromecast.

After problemless function for years it was'nt working anymore. Restarting modem and chromecast without succes I was suggested to reset factory settings. Starting is okay untill the message to download the app. Starting Google Home I succesfully start adding Chromecast to my app Home (tv screen displays a for character code) untill the message on my Phone saying that Googlecast cannot be verified.

Lots of retries all ends with the same error. What to do to make IT work again?

[Luckyvis]

Welcome to the club. Its a worldwide issue with a certificate which has not been renewed in time. Since this weekend many Chromecast gen 2 are not working anymore. Google advices not to do a factory reset but unfortunately a lot of us did including me. They are now working on the problem. 

[gilbertotron]

This might sound mad but if you set the date of your phone manually back to the 8th of March and try again it'll connect and work. 

Strange but true.

[Homealone2]

Tried this without luck. Maybe because I had already done a restart of the Chromecast?

Does anyone know when they will have a fix? And why they haven’t updated their troubleshooting guide……

[Jey666]

Not really true. By rolling back the device date you can connect the chromecast with the Google home app. However, some streaming still doesn't work. Example VLC works! Device screen casting not working!

[JJsumu]

I have exactly the same problem, before past weekend.

I'm waiting for a Google home actualitation or something

[Derri]

Same issue. Changing the date seems work to connect the chromecast to the WiFi but I cannot cast netflix or YouTube..
