Older Chromecast devices are failing to connect globally

Many Google Chromecast users reported issues with their older devices over the weekend. Users on Reddit stated that their 2nd generation Chromecast and Chromecast Audio devices cannot authenticate when trying to connect. Affected users have tried common troubleshooting methods, such as restarting and factory resetting their devices, but these have not resolved the problem. The issue appears to be linked to the verification firmware and affects only older models. Google has not commented on the situation, and there are no announcements about dropping support for these devices. Newer models, like the Chromecast 3rd Gen and Chromecast Ultra, continue to function normally.
