Second-generation Chromecast and Chromecast Audio devices are facing a problem that prevents them from casting content. If you try to use an affected device, you'll see one of two errors -- either, "Untrusted device: [name] couldn't be verified. This could be caused by outdated device firmware," or "We couldn't authenticate your Chromecast."

Over the weekend, 9to5Google reported that second-gen Chromecast and Chromecast Audio devices displayed an “Untrusted device” error message, preventing users from casting audio and video content onto their screens of choice.

Chromecast (2nd Gen) and Audio users are locked out of streaming due to an "Untrusted Device" error—here's why it's happening and what to expect next.
