Google has apologized to its users for a widespread outage affecting certain Chromecast models, which has been causing "Untrusted device" errors when trying to cast content. The tech giant has acknowledged the issue and promised to roll out a fix as soon as possible.

The issue, which started over the weekend, has been causing frustration among Chromecast users who have been unable to cast content to their devices. Google has emailed affected users, apologizing for the disruption and assuring them that the company is working on a solution. The email, titled "Important information about your Chromecast," states that the company is "working to roll out a fix as soon as possible" and will share updates and guidance on the Nest Community page.

When reached for comment, Google acknowledged the issue and said it would share more information as it became available. A Google Nest Community Manager later confirmed that the team had "identified the cause of the issue" and was working on a fix, although the company has not disclosed what caused the problem.

One Reddit user has speculated that the issue may be related to an expired certificate baked into the Chromecast, which became invalid after March 9th, 2025. While this has not been officially confirmed by Google, it provides a possible explanation for the sudden onset of the issue.

The Chromecast outage is a significant issue for Google, which has been investing heavily in its smart home ecosystem. The company's Chromecast devices are popular among users who rely on them to stream content to their TVs and other devices. Any disruption to this service can have a significant impact on user experience and loyalty.

Google's prompt apology and promise to fix the issue as soon as possible are likely to be seen as a positive step by users. However, the company will need to move quickly to resolve the issue and prevent further disruption to its users. The incident highlights the importance of robust testing and quality assurance processes to prevent such issues from occurring in the first place.

As the smart home market continues to grow, incidents like this Chromecast outage serve as a reminder of the importance of reliability and stability in connected devices. Google's response to this issue will be closely watched by users and industry observers alike, and will likely have implications for the company's reputation and market position in the smart home space.
