Chromecast 2nd Gen Outage: Users Facing 'Untrusted Device' Error

Thousands of users of Google's Chromecast (2nd Gen) and Chromecast Audio are experiencing connectivity issues. The error started appearing at 6 pm last Sunday, 09 Mar 2025. Users encounter errors when trying to cast content. The error shows a pop-up with an "Untrusted device" message, which states:

While Google has not officially announced the discontinuation of Chromecast (2nd Gen) or Chromecast Audio, the issue has led many users to believe that their devices are being silently phased out.

Google discontinued the Chromecast lineup in August 2024 but assured that users will still get software and security updates. However, with no immediate fix available, could this be an indication of the end for these devices?

Reports suggest that the root cause of this outage is an expired authentication certificate, making affected devices unable to verify their connection.

Despite the issue being global, newer Chromecast models, such as the Chromecast (3rd Gen) and Chromecast Ultra, remain unaffected.

Google hasn't officially acknowledged the problem yet. So, there is no timeline for when the affected devices will be back online.

As of now, there are no user-side fixes available. Restarting or resetting the Chromecast does not resolve the problem. The only option is to wait for an official fix from Google.

Will you wait for Google's update, or are you considering switching to a newer streaming device? Share your thoughts in the comments!
