Why your Chromecast showing an “Untrusted device” error

Reports indicate that owners of the second-generation Chromecast and Chromecast Audio devices are encountering an “Untrusted device” error, preventing them from casting content. This issue emerged today, drawing attention to concerns over the devices’ support status, according to 9to5Google.

Users have shared screenshots of the error on Reddit, displaying the message: “Untrusted device” followed by “couldn’t be verified. This could be caused by outdated device firmware.” Many users fear that Google may have deprecated these older models, similar to the original Chromecast announced in 2023.

At least one community member reported contacting Google support, who acknowledged the issue and noted that a fix is forthcoming. Google has not provided any official comment regarding the situation. The company discontinued the Chromecast line in August 2022 but committed to continued software and security updates for its latest devices.

The error has rendered the affected models unusable for streaming audio and video content. Users experience the same “Untrusted device” message across all apps, including YouTube, when attempting to cast. The only option available is to close the error dialog, with no workarounds, reboots, or resets resolving the issue. However, the screensaver functionality, which displays Google Photos and other visuals, remains operational.

Newer models, like the Chromecast (3rd gen) and Ultra, appear unaffected by this issue. The current “Untrusted device” alert has prompted speculation that Google may have bricked the older devices or is signaling an end-of-life announcement. However, experts suggest that this is likely just a bug, as Google has made no similar deprecation announcements for these models as it did for the original Chromecast in May 2023, which still functions today.

Both the Chromecast (2nd gen) and Chromecast Audio were launched in September 2015 and run on 1.56.x firmware. As users await a resolution, many express disappointment if these iconic devices are approaching obsolescence.
