Chromecast Recovery Update: Google Releases Fix for Devices Affected by Outage

In light of the recent issues that rendered many Chromecast (2nd Gen) and Chromecast Audio devices inoperative, Google has responded by providing a solution. After a week's effort, engineers at Google have implemented a fix aimed specifically at users who experienced problems following a service outage caused by an expired authentication certificate. Here’s what you need to know to get your devices up and running again.

Update: For Chromecast owners who made the decision to reset their devices, Google has issued a new update. Users are required to update the Google Home app to the latest version (3.30.1.6 for Android and 3.30.106 for iOS) in order to set up their Chromecast (2nd gen) or Chromecast Audio device again.

The rollout of this new update may take several days, so while the deployment starts today, it may not be available to everyone immediately. Keep an eye on the Google Play Store or the App Store for the latest version.

Original story: If your Chromecast stopped functioning after last week’s outage, there's good news. Google has finally rolled out a fix after a week of efforts, although users who performed a factory reset during troubleshooting might still encounter some issues.
