The causes of server issues aren’t always immediately obvious. The best place to start is the server output: if you set up Craftopia using the Game Server Installer, you can find it at C:\ZapX-GameServers\craftopia\logs\server.log. The installer logs restarts after crashes in logs\supervisor.log.
Craftopia doesn’t appear in a server list, so you connect directly using the IP address and port. If that doesn’t work, first check server.log to see whether the server is running and has finished starting up. The first startup takes about two minutes. Then check that the port is open in the Windows Firewall and in your VPS’s network firewall. Find out which port to use in Craftopia: Set up a server on your VPS.
Start the server via Remote Desktop using the Craftopia (craftopia) - Start shortcut and check server.log. The first startup creates the world and takes about two minutes. Common causes include a typo in ServerSetting.ini, a port already in use by another program, or insufficient memory. If you changed the configuration, try reverting the change to see if that fixes the issue.
Nothing cuts a good session short faster than an unexpected crash. Possible causes include an outdated server version, modified game files, an overloaded VPS, or an incorrect configuration. The installer automatically restarts your server after a crash. If it crashes several times in a short period, the installer stops trying. 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An outdated server can cause crashes, unexpected behavior, or startup issues, and often prevents players with a newer game version from connecting.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 Craftopia. It will then show Update. Alternatively, use the Craftopia (craftopia) - Update shortcut on your VPS.
Crashes after a change are often caused by additional or modified files in the server folder, especially after a game update. Try removing any additional content and starting with a minimal configuration. If the issue goes away, add your changes back one at a time and test after each step. This helps you pinpoint what’s causing the problem.
Issues like lag or delays often occur when the configuration isn’t suitable, the VPS doesn’t have enough resources, or too many players are online at once.
Unsuitable settings can increase resource usage and cause lag. Check the values in server\ServerSetting.ini, such as the number of player slots (maxPlayerNumber) or the enemyPoolSizeRate value. Stop the server with Craftopia (craftopia) - Stop before editing the file.
Craftopia needs at least 7 GB of memory. While the world is being created, the server alone can temporarily use around 4 GB. The operating system and other programs on the VPS also need resources. You can see how heavily your VPS is being used in the ZapX dashboard under Monitoring. If memory or CPU usage is consistently maxed out, upgrading your VPS can help. Learn more in Upgrade, downgrade, renewal, and cancellation.
Ping spikes and lag are usually caused by limited VPS resources, a large number of players, or a server location far away from your players. First, check resource usage under Monitoring. If you suspect routing issues, Diagnose network issues with WinMTR/MTR can help. If you’re still stuck, 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 problems, contact our support team.
Regular backups can save you a lot of stress. Use the Craftopia (craftopia) - Backup shortcut to save your worlds, player data, and settings as a ZIP file whenever you want. Use Craftopia (craftopia) - Restore 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. Learn more in Daily backups, restoring data, 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! 🙂
