(macOS) Live Playback Expiration Error

Notice

This document is a machine-translated draft and is currently undergoing review. Some content may be inaccurate or differ from the original Korean version. For the most precise information, refer to the Korean documentation.

Symptoms

When watching a live stream on macOS, the message "The playback validity period has expired." appears and viewing is unavailable.

Cause

This occurs when the computer's time zone is set to a region other than Korea (Seoul). The player incorrectly calculates the server's validity period, causing playback to be blocked.

Solution

Change the time zone to Korea (Seoul) in the macOS date and time settings.

1. Go to [System Settings] > [General] > [Date & Time].
2. Under the Time Zone section, select Korea - Seoul.
3. Restart your browser and play the live stream again.

Note

For detailed instructions on macOS date and time settings, refer to the Apple official guide.
