The cause of server issues isn’t always immediately obvious. The best place to start is the server output: if you set up TerraTech Worlds using the Game Server Installer, you’ll find it at C:\ZapX-GameServers\terratech-worlds\logs\server.log. Restarts after crashes are logged by the installer in logs\supervisor.log.
If your server doesn’t appear in the server list, first check whether it’s running and has finished starting up. Check server.log to confirm. The first startup takes about 30 seconds while the planet loads. Then check that the ports are open in the Windows firewall and your VPS’s network firewall. You can find out which ports TerraTech Worlds needs in TerraTech Worlds: Set up a server on your VPS. Also make sure there aren’t any filters active in the server list that could be hiding your server.
Start the server via Remote Desktop using the TerraTech Worlds (terratech-worlds) - Start shortcut and check server.log. Common causes include an error in dedicated_server_config.json (the file is JSON, so even a missing comma is enough), a port already in use by another program, or insufficient memory. If you’ve changed the configuration in server\dedicated_server_config.json, try reverting the change to see if that fixes the issue.
Nothing ends a good session faster than an unexpected crash. Possible causes include an outdated server version, an overloaded VPS, or a misconfiguration. The installer automatically restarts your server after a crash. If it crashes several times in quick succession, the installer gives up. You’ll then need to fix the cause and start the server yourself.
An outdated server can cause crashes, unexpected behavior, or startup issues, and often prevents players from connecting with a newer game version. Updates aren’t installed automatically. Open the Game Server Installer again and select TerraTech Worlds; it will then show Update. Alternatively, use the TerraTech Worlds (terratech-worlds) - Update shortcut on your VPS.
In TerraTech Worlds, the server name in the installer is the name of the save. If you changed it, the server will start with a different save. Run the installer again with the old name to load your existing world.
Issues like lag or delays often occur when the configuration isn’t right or the VPS doesn’t have enough resources.
Unsuitable settings can increase resource usage and cause lag. Check the values in server\dedicated_server_config.json, such as the player limit (8 maximum). Stop the server before editing the file. Change the port, player limit, password, save, and planet through the installer, which overwrites these values every time it runs.
TerraTech Worlds needs at least 6 GB of memory. The operating system and other programs on your VPS need additional resources. You can check how heavily your VPS is being used under Monitoring in the ZapX dashboard. If memory or CPU usage is consistently maxed out, upgrading your VPS may help. Find out more in Upgrade, downgrade, renewal, and cancellation.
Ping spikes and lag are usually caused by limited VPS resources, a high number of players, or a server location far from your players. First, check usage under Monitoring. If you suspect routing issues, Diagnose network issues with WinMTR/MTR can help. If you’re still having trouble, contact our support team.
Game servers are occasionally targeted by DDoS attacks, which 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 TerraTech Worlds (terratech-worlds) - Backup shortcut to back up your worlds and settings as a ZIP file at any time, and the TerraTech Worlds (terratech-worlds) - Restore shortcut to restore them. Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. Find out more in Daily backups, restoring, and locked actions.
These steps should help you resolve the 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! 🙂
