Overview

• An expired security certificate on March 9, 2025, caused second-generation Chromecast and Chromecast Audio devices to stop casting content.
• Affected users encountered 'untrusted device' error messages, preventing the devices from connecting to Google's backend systems.
• Google has acknowledged the issue and is working on a fix, advising users not to perform a factory reset as it will not resolve the problem.
• A workaround involving manually adjusting device dates has been shared online but is inconsistent and may not fully restore functionality.
• While the Chromecast product line was discontinued in 2023, Google has committed to resolving this issue for existing users.
