Google fixes casting issues for Chromecast devices

Google is addressing issues with Chromecast devices that prevented users from casting. The fix is being rolled out and should be completed in the next few days. The problem affected many Chromecast 2nd generation and Chromecast Audio devices, causing "untrusted device" errors. Users speculated that an expired certificate may be the cause. Google advises that devices must be connected to receive the update. Users who performed a factory reset may still face setup issues, and Google is working on a resolution.
