The causes of server issues aren’t always immediately obvious. The first place to look is the server output: if you set up Battle Grounds III using the Game Server Installer, you’ll find it at C:\ZapX-GameServers\battle-grounds-iii\logs\server.log. The installer logs restarts after crashes in logs\supervisor.log.
If your server doesn’t appear in the server list, first check that it’s running and has loaded the map. Check server.log to confirm. Next, make sure port 27015 (TCP and UDP) is open in the Windows Firewall and in your VPS’s network firewall. For details, see Battle Grounds III: Set up a server on your VPS. Also make sure there are no filters enabled in the server list that could hide your server.
Start the server via Remote Desktop using the Battle Grounds III (battle-grounds-iii) - Start shortcut and monitor server.log. Common causes include a typo in server.cfg, a port already in use by another program, or insufficient memory. If you’ve changed the configuration, try reverting the change to see if that fixes the issue.
Nothing ends a good session faster than an unexpected crash. Causes may include an outdated server version, faulty custom content, an overloaded VPS, or a misconfiguration. The installer automatically restarts your server after a crash. If it crashes several times in a short period, the installer gives up. You’ll then need to fix the cause and restart the server yourself.
An outdated server can cause crashes, unexpected behavior, or startup issues, and often prevents players with a newer game version from connecting. Updates aren’t installed automatically. Open the Game Server Installer again and select Battle Grounds III; it will then show Update. Alternatively, use the Battle Grounds III (battle-grounds-iii) - Update shortcut on your VPS. An update resets server.cfg and permissions.res, so back up your changes first using the backup shortcut.
Crashes are often caused by faulty or outdated custom content, such as mods or custom maps, especially after a game update. Try removing any custom content and starting with a minimal configuration. If that fixes the issue, add the content back one step at a time, testing after each step. This helps you pinpoint exactly what’s causing the problem.
Issues such as lag or delays often occur when the configuration isn’t suitable, the VPS doesn’t have enough resources, or custom content overloads the system.
Unsuitable settings can lead to higher resource usage and lag. Check the settings in server\bg3\cfg\server.cfg. Stop the server before editing the file. Keep in mind that an update resets server.cfg to the supplied version.
Battle Grounds III requires at least 3 GB of memory. The operating system and other programs on the VPS need additional resources. You can check your VPS’s resource usage in the ZapX dashboard under Monitoring. If memory or CPU usage is consistently maxed out, upgrading your VPS can help. For details, see Upgrade, downgrade, renewal, and cancellation.
Ping spikes and lag are usually caused by limited VPS resources, a high player count, or a server location far from your players. First, check resource usage under Monitoring. If you suspect routing issues, see Diagnose network issues with WinMTR/MTR. If you still need help, contact our support team.
Game servers are sometimes targeted by DDoS attacks that flood the server with traffic. Your VPS is protected by our DDoS protection. You can view past attacks in the DDoS Manager for your VPS in the ZapX dashboard, if it’s available at your location. If you suspect an attack is causing issues, contact our support team.
Regular backups can save you a lot of stress. Use the Battle Grounds III (battle-grounds-iii) - Backup shortcut to back up your server settings, admin roles, and ban lists to a ZIP file at any time. Use Battle Grounds III (battle-grounds-iii) - Restore to restore a backup. In addition, your entire VPS is backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. Learn more in Daily backups, restoration, and restricted actions.
These steps should help you resolve your issue. If they don’t, feel free to contact our support team: simply start a support chat in your ZapX customer account. We’re here for you every day and happy to help! 🙂
