That's not how certificates work unfortunately.  They are a security measure that should be renewed periodically.  Where they dropped the ball was not renewing it before it expired.

[Danielmm]

Certificares needs to expire

[Danielmm]

Certificates needs to expire. 

[TamCaviar]

tijdens de launch in, 2015 zijn er al meer dan 100 miljoen chromecast 2nd gen verkocht, dit liet Google weten..

dit certificaten probleem is echt niet leuk, achterstallig onderhoud, na 4 dagen nog geen enkele update of bruikbare  oplossing..

why🤷... 

[michiel3000]

These things happen.

[Jimmy53]

What they want is us to buy the New device. The Google Streamer which is a lot more expensive. They kniwingly ruined Chromecast .

[Dizzy1]

that completely flies in the face of planned obsolesence.
sure this certificate issue was a slip, but do not think that this is not baked in... they already have selected the end date for the 2nd gen.

[HarryE1965]

sjonge denk je nu echt dat het nalatigheid is? Zelfs al heb je nog zulke goede checks dan nog kan er gewoon iets fout gaan. Het is niet zo simpel en zwart wit als jij het nu doet voorkomen. Me dunkt dat ze bij Google wel professionals in dienst hebben. Alleen in dromenland heb je perfecte grip op alle processen

[Greasewolf]

1̶0̶0̶0̶s̶

Try 10000000s

[RobzillaRock]

How many customers were affected? Thousands? Prove it!  It would be a shame if someone were involved in foul play. Get their rocks off that way before they go back to a miserable life again.  

[Djb200]

What are you talking about?  It's not a murder mystery. Google messed up. And yesterday 100s of thousands will have been affected.

[NedDefiance]

No! Certificates should have a reasonable expiration date. What needs to be done is a check for expiration and updates. 

[1ml]

Like they care. If it hadn't made the news they wouldn't have done anything.

[Poofox]

For real. I already reset mine so I hope they come up with a fix soon

[FahadKhan911]

Try to update your device date to 1st March 2025 and then connect chromecast to get updated.it will be working after taking time to update.

[Lauwinter59]

de qué modo nos harán saber cuándo estará lista la solución? 

[Mojy]

It has been over a week now.

[Stillhere]

Global outgage.

Probably millions were affected.

[dasman1]

Saya hanya ingin di perbaiki saja

[LearnbyHeart7]

Mine is still not working...in NC.  They just installed Google Fiber in our neighborhood and then my 2 Chromecasts went out.  

[MJ18]

Claro una certificación que Google "olvido" renovar..

[CostasV1969]

Hello my friend. I think is not so easy. Google stopped selling Chromecast devices and they decided to stopped to support it.

[ccouto]

stop support is one thing, enter in my home and destroy silently, without adivise me in advance is another.

[Heidi5]

No se lo cree nadie verdad

[Jimmy53]

Eso fue premeditado para obligarnos a comprar el nuevo dispositivo, el Google Streamer el cual es mucho más costoso. Esa gente no da puntada sin dedal.

[56Fe]

Podian poner la caducidad en 100 años si querian evitar eso

[Dipkingen]

Must be easy to fix ...

[LittleTyke]

One would think so, but the issue is now at least 24 hours old and there's no sign of a fix from Google. I went to Argos today and bought the Amazon Firestick HD.

[Dado1979]

LOL 

[Greeneyedjade]

Please let me know if you know a way to cast to it from a Google phone

[Linrick04]

If the cert becomes past due and a new product is on the horizon?

[solea]

Oui le certificat SSL ils ont oublié de faire la MAJ pour les Chromecast 

[kockaslasen]

There are a lot of chinese clones on Amazon and AliBaba - I'll buy one of those instead.

[underwhelmed]

I renew certificates everyday, would they like me to take over?

[DVDMike]

It really doesn’t matter what the specific cause was, just that the outage is due to a problem at Google and there is nothing a user can do but complain. 
an expired certificate would indeed be an unforgivable mistake by a company such as Google, if indeed that’s the root cause. Imagine if Google mail went down for all customers because of an expired certificate? This would make the nightly news and Google executives would be brought before Congress to account—and that from a service that most Americans use for free.

i truly don’t believe a a certificate was really to blame. It’d be fixed by now if that were the only reason. A company like Google doesn’t let certificates expire unless they want to. 

but again, the cause is internal to Google. While interesting to those of us in the tech world, the users are not meant to care why. Users just want things to work. In the grand scheme of things why is way down the list to most users since users cannot fix the issue on their own. 

[EddieRock]

In this day and age, a root certificate should never need to be maintained by humans. This should 100% be automated! I am floored that Google was affected by this. 

[RichBerke]

10 year certs are reasonable. There just needs to be a way to move over to a newer cert. Almost no end user can, nor should have to, mess around with this.  Power off and power on should be the process, but it's not yet available. 

[PlagueSD]

Expired cert. That should only take a few mins to fix. Takes us about 30 minutes to update expired certificates where I work. 

[BadFlash]

There’s like 100M Chromecast certificates to resign … not sure how google will fix this .  Use a unique common certificate ?  Generate a new self-signed certificate on the fly ?  Generate a unique firmware for each Chromecast so they can have a unique certificate ?

[Albe1983]

Something that even smallest companies doesn't forget... what a mess Google... just after Pixel 4a, time to think to an alternative.
