Google is actively addressing a technical issue that has left many Chromecast users unable to stream content on their televisions for a second consecutive day.

The problem specifically affects the second-generation Chromecast model, part of a product line that has sold over 100 million units worldwide. Users have reported being unable to connect their devices to their TVs, preventing them from accessing streaming services like Netflix and YouTube. Chromecast Audio devices have also been impacted.

In a post on the Google Nest support forum, the company advised users not to attempt a factory reset on affected devices, warning that doing so could complicate the issue."

Do not factory reset your device—we will keep you all updated when the fix rolls out," the company stated. "If you have already factory reset your device, we will provide instructions to set your device back up as soon as possible."

However, some users on social media pointed out that this advice came too late, as many had already attempted a factory reset to troubleshoot the issue.

"Factory reset is literally the first thing I did when my Chromecast stopped working," one user wrote on X. Another commented, "Google asking everyone to please not factory reset their Chromecast after hours, when it's one of the most common fixes, is hilarious."

Chromecast devices allow users to stream videos, music, and other content wirelessly from their phones, tablets, or laptops to a TV. They also enable users to cast web browser tabs via Google Chrome.

Reports of connectivity issues began on Sunday evening, with users encountering error messages stating their devices could not be authenticated, their connections had failed, or that their Chromecast was "untrusted."

Last August, Google announced plans to discontinue Chromecast and transition to a new Google TV system. Despite this, the company had assured users that existing Chromecast devices would continue receiving support.

According to The Register, the issue may stem from an expired authentication certificate, though Google has yet to confirm this. The BBC has reached out to the company for further clarification.
