Project Zomboid Server Troubleshooting
Fix common PZ server problems — sandbox not applying, mod errors, connection issues.
Sandbox Changes Not Applying
Delete map_sand.bin from the save folder and restart. This forces the server to reload sandbox settings.

"Failed to Connect"

- Verify password if set
Can't Become Admin
