Chromecast “Untrusted Device” Error Fixed—Here’s What You Need to Know
If your older Chromecast device recently stopped working due to an “untrusted device” error, there’s good news: Google has issued a fix that should restore functionality within the next few days.
The issue, which affected the Chromecast 2nd Gen and Chromecast Audio, left many users frustrated as their devices suddenly refused to stream content. The error message read:
“Untrusted device: [name] couldn’t be verified. This could be caused by outdated device firmware.”
As reports of the issue flooded Reddit and other forums, speculation grew that Google might have quietly ended support for these aging Chromecast models. The timing of the problem didn’t help—just last month, Google stopped selling the Chromecast with Google TV, pushing users toward its new $100 Google TV Streamer.
However, Google has now confirmed that this was a bug rather than an intentional shutdown of older devices. The company shared in an email (posted on Reddit) that a fix is actively rolling out and advised users to keep their devices connected to Wi-Fi so they receive the update automatically.
Reports from 9to5Google indicate that some Chromecast owners are already seeing their devices work again, and Google expects the update to reach all affected users within a few days.
The cause of the issue remains unclear, but some users speculate that expired SSL certificates were responsible, leading to authentication failures that made Google’s servers reject the older Chromecast devices.
For now, if you were affected by this frustrating glitch, your best course of action is to wait for the fix to reach your device—and whatever you do, don’t factory reset your Chromecast, as it won’t speed up the update process.
With this fix on the way, Chromecast 2nd Gen and Chromecast Audio owners can finally get back to streaming without worrying that their devices are permanently obsolete.
