Google Fixes Chromecast (2nd Gen) and Chromecast Audio Outage – Here’s What You Need to Know

Google Fixes Chromecast – Here’s What You Need to Know

In early March 2025, numerous users of second-generation Chromecast and Chromecast Audio devices encountered significant issues, rendering their devices inoperative. The problems began around March 9, when users reported receiving “Untrusted device” errors, preventing them from casting content. This disruption was widely attributed to an expired authentication certificate within the affected devices.

Google promptly acknowledged the issue and assured users that a fix was underway. On March 13, the company announced the rollout of an update designed to resolve the problem for most users. They advised users to keep their devices connected to Wi-Fi to receive the update automatically. However, Google cautioned against performing a factory reset during this period, as it could complicate the restoration process.

Despite these warnings, some users attempted factory resets, leading to further complications, including difficulties in reconfiguring their devices. In response, Google released an additional update on March 17, specifically targeting devices that had been factory reset. This update required users to update their Google Home app to the latest version—3.30.1.6 for Android and 3.30.106 for iOS—to facilitate the reconfiguration of their Chromecast devices.

To ensure your Chromecast (2nd gen) or Chromecast Audio device functions correctly, verify that it has received the latest firmware update. If issues persist, updating the Google Home app and attempting to reconfigure the device is recommended. Google has expressed regret for the inconvenience caused and is committed to restoring full functionality to all affected users.

If you own a Chromecast (2nd Gen) or Chromecast Audio, here’s what you need to do:

1. If you didn’t factory reset your device:

   • Your Chromecast should now work automatically.
   • If it’s still not working, check the firmware version in the Google Home app.
   • If needed, restart the device to trigger the update.

2. If you did a factory reset:

   • You must update the Google Home app to the latest version:
     • Android: 3.30.1.6
     • iOS: 3.30.106
   • After updating, reconfigure your Chromecast.

Google is rolling out the Google Home app update gradually, so if you don’t see it yet, wait a few days.

Next Steps:
✔️ Keep your device connected to Wi-Fi.
✔️ Check for updates in Google Home app.
✔️ Avoid resetting your device again.
