How do I update my ASTRONEER server?

Open the Game Server Installer again and select ASTRONEER. It will display Update. Alternatively, use the ASTRONEER (astroneer) - Update shortcut on your VPS.

Which port does an ASTRONEER server need?

The default is 7777 (UDP). The installer opens it in the Windows Firewall and, when you install from the dashboard, in your VPS's network firewall too.

Introduction

Run your own ASTRONEER server on your VPS with ZapX. You have full control over the system, and the Game Server Installer gets your server set up in just a few minutes—no Remote Desktop connection required. This guide explains what you need, how to install the server, and how to manage it afterward.

Requirements

Requirement	ASTRONEER
Operating system	Windows Server 2019 or later
Memory	at least 4 GB
Free disk space	at least 6 GB on drive C:

Info

ASTRONEER is only available for Windows in the Game Server Installer. If your VPS runs Linux, install a Windows Server template via Settings > Reinstallation. This deletes all data on your VPS. Learn more in Server Reinstallation.

Install ASTRONEER

Open your VPS in the ZapX dashboard and go to the Tools tab. Select the Game Server Installer.
Under Your server's operating system, select the Windows tile.
Under Choose game, search for ASTRONEER and select it.
Under Set up server, specify the Server name and Player slots. You can find the Game port under Advanced settings.
Click Install on this VPS, then click Start installation.

The installer downloads the ASTRONEER server via SteamCMD, sets it up, and starts it. For more details on the installation process, see the Game Server Installer guide.

Important

The first player to join a server without an owner automatically becomes its owner and admin. So make sure you connect to your server first after installation.

You can also install ASTRONEER manually using a command: Copy the command shown in the final step, connect using Remote Desktop, and run it in Windows PowerShell as an administrator. To set a join password, use this method: the script will prompt you for it without displaying it.

After installation

Once installation is complete, the installer displays your server address under How to connect. Any passwords generated by the installer are shown once under Login credentials. For instructions on how to connect, see ASTRONEER: Connect to the Server.

Your server files are located on the VPS at C:\ZapX-GameServers\astroneer\:

Folder/file	Contents
`server\`	ASTRONEER server files
`server\Astro\Saved\SaveGames\`	Saved games
`server\Astro\Saved\Config\WindowsServer\`	Settings in `AstroServerSettings.ini` and `Engine.ini`
`logs\supervisor.log`	Restarts after crashes

Info

ASTRONEER does not create a log file, and server output is not recorded either.

Start, stop, and restart the server

Your ASTRONEER server starts automatically when the VPS boots and restarts after a crash. To manage it, connect using Remote Desktop and use the desktop shortcuts:

ASTRONEER (astroneer) - Start
ASTRONEER (astroneer) - Stop
ASTRONEER (astroneer) - Restart

Configuration

ASTRONEER settings are stored in server\Astro\Saved\Config\WindowsServer\AstroServerSettings.ini, such as OwnerName or AutoSaveGameInterval. The game port is set in Engine.ini in the same folder.

Stop the server using ASTRONEER (astroneer) - Stop before editing the files, then start it again afterward. The Stop shortcut saves the world before shutting down the server. The installer rewrites the server name, player slots, join password, port, and public IP address every time it runs, including during an update.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select ASTRONEER. The installer detects the existing installation and displays Update. Alternatively, use the ASTRONEER (astroneer) - Update shortcut on the VPS. Your saved games and settings are preserved.

Ports and firewall

Port	Protocol	Use
7777	UDP	Game

The installer opens this port in the Windows Firewall. If you start the installation from the dashboard, it also opens the port in your VPS's network firewall. If you installed using a command, check the port there yourself.

The server console uses another port, which is only used by the Stop shortcut to shut down the server safely. The installer deliberately does not open this port.

Backups

Use the ASTRONEER (astroneer) - Backup shortcut to back up your saved games and server settings as a ZIP file at C:\ZapX-GameServers\_backups\astroneer\. Use ASTRONEER (astroneer) - Restore 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, Restoring Data, and Restricted Actions.

Conclusion

Your ASTRONEER server is now running on your VPS. Remember to connect first so you become the server owner. If you have questions or need help, our support team is available every day! 🙂
