Has your outdated Chromecast instantly developed an issue?
You are not alone it appears.
Many customers of second-generation Chromecast and Chromecast Audio streaming gadgets have found that their beloved dongles have gone belly-up and are exhibiting error messages corresponding to:
“Untrusted system: [name] could not be verified. This might be brought on by outdated firmware.”

And what has the standard tech consumer learnt over time if a chunk of {hardware} is not working correctly? Why, do a manufacturing unit reset in fact!
Woah! Cease proper there – as a result of Google is advising Chromecast homeowners to not make the error of considering that performing a manufacturing unit reset on their Chromecasts will repair the difficulty.

Certainly, Google goes on to elucidate that in case you carry out a manufacturing unit reset whereas attempting to troubleshoot the difficulty together with your Chromecast, chances are you’ll end up unable to re-setup your system.
Google says it’s engaged on the difficulty, and can maintain customers up to date through its Nest Neighborhood web page when it has extra to share.
The unique “untrusted system” downside seems to be linked to an intermediate Certificates Authority (CA) that expired on Sunday 9 March 2025. When initially issued the certificates was set to run out after ten years and – yup! – it appears no-one at Google has renewed it for the reason that launch of the Chromecast.
This has meant that Google’s servers can not authenticate that older Chromecasts are real, and ends in the show of the error message.
In accordance with a report in The Verge some Chromecast customers have acquired an apology e mail from Google for the inconvenience:
We’re contacting you due to a disruption affecting Chromecast (2nd gen) and Chromecast Audio gadgets. We apologize for the difficulty and perceive your frustration. We’re working to roll out a repair as quickly as potential and can share updates and steerage on the Nest Neighborhood web page. We recognize your endurance as we resolve this situation.
I feel it is protected to foretell that Google ought to have the ability to repair the issue, though it could take longer than just some days. Little doubt the dearth of a repair will go away some customers disgruntled or baffled as to why they don’t seem to be capable of stream their favorite movies and TV exhibits for the previous couple of days.
