Big Walk Connection Error Caused by Date and Time

The useful answer
Set the PC or console date, time and timezone to automatic, then restart Big Walk. An incorrect system clock can prevent secure session connections.

Step by step
- Open system date and time settings.
- Enable automatic time and timezone.
- Synchronize now.
- Restart the game and retry the live code.
Why players get stuck here
This is easy to miss on Switch 2 or a console that has been offline because every other network setting can look correct.
Why an incorrect clock blocks multiplayer
Online session security depends on timestamps. A device can browse the web normally yet reject hosting and joining when its clock is far from online time. Enable automatic date, time and timezone, force a synchronization and perform a full restart.
If every player has accurate time but only one still fails, move on to version matching and network checks; do not keep regenerating codes as the only test.
Verify it before moving on
Change one variable at a time, then retest from a fresh session. That makes it clear which fix worked and avoids turning a connection, audio or input problem into several overlapping problems.
