Google's 10-year-old Chromecast is suddenly broken - here's what's going on

Google's second-generation Chromecast and Chromecast Audio devices are experiencing an "Untrusted Device" error.

The issue is affecting all owners of the devices, and Google is actively working on a fix. Google is asking users not to factory reset their devices and await a fix.

The issue may be linked to an expired certificate. Google has apologized for the error and will provide updates through its Nest Community.
