Secure connections and time-limited credentials depend on a reasonably accurate clock. A player with a date far in the past or future may reject certificates or present expired access information even when the entered username is correct.
Look beyond the displayed hour
Check the year, date and time zone, then use automatic time synchronisation where supported. A wrong time zone can confuse programme listings even when the underlying clock is close. Those are related but distinct settings.
Reconnect after correction
Restart the affected app once so it can establish a fresh connection. Do not repeatedly clear storage before testing the corrected clock. Saved credentials and favourites may be unrelated to the original failure.
Watch for recurrence
If the date resets after every power interruption, consult the device manufacturer's troubleshooting guidance. A service password change will not repair a device that cannot retain or synchronise its time correctly.
