The causes of server issues are often not immediately obvious. ASTRONEER doesn’t create a log file, so first check whether the server is running at all: look for the AstroServer-Win64-Shipping.exe process in Task Manager. If you set up ASTRONEER using the Game Server Installer, the installer logs restarts after crashes in C:\ZapX-GameServers\astroneer\logs\supervisor.log.
If you can’t connect to your server, first check in Task Manager whether it’s running. Then check that the game port is open in the Windows Firewall and the network firewall for your VPS. For more information, see ASTRONEER: Set up a server on your VPS. The server tells the game the public IP address of your VPS, which the installer enters in AstroServerSettings.ini. If you changed anything there, run the installer again.
Start the server via Remote Desktop using the ASTRONEER (astroneer) - Start shortcut, then check in Task Manager whether the process keeps running. Common causes include a typo in AstroServerSettings.ini or Engine.ini, a port already in use by another program, or insufficient memory. If you changed the configuration, try reverting the change. If the installer gives up after multiple crashes, you’ll see this in logs\supervisor.log.
Nothing ends a good session faster than an unexpected crash. Causes can include an outdated server version, faulty additional content, an overloaded VPS, or a misconfiguration.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An outdated server can cause crashes, unexpected behavior, or startup issues, and often prevents players from connecting with a newer game version. Updates aren’t installed automatically. Open the Game Server Installer again and select ASTRONEER; it will then show Update. Alternatively, use the ASTRONEER (astroneer) - Update shortcut on your VPS.
Crashes are often caused by faulty or outdated additional content, such as mods or custom maps, especially after a game update. Try removing additional content and starting with a minimal configuration. If the issue goes away, add the content back one item at a time and test after each step. This will help you pinpoint 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 additional content overloads the system.
Unsuitable settings can lead to higher resource usage and lag. Check the values in server\Astro\Saved\Config\WindowsServer\AstroServerSettings.ini, such as the number of player slots. Stop the server before editing the file.
ASTRONEER requires at least 4 GB of memory. The operating system and other programs on the VPS need additional 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. For more information, 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 ASTRONEER (astroneer) - Backup shortcut to back up your save games and settings as a ZIP file at any time, and the ASTRONEER (astroneer) - Restore shortcut to restore a backup. 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, restoration, and restricted actions.
These steps should help you resolve your issue. If they don’t, don’t hesitate 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! 🙂
