How to create a Star Rupture server: complete 2026 guide

You're hooked on Star Rupture and want to take on Arcadia-7 with your buddies? Good news: the game supports dedicated servers from early access. This guide shows you the two methods available to create a server — free self-hosting (but technical) and managed hosting (simple and stable).

Why create your own Star Rupture server?

Before diving into the technical side, it's worth recalling what you gain from running your own server:

• Play with your friends anytime, without having to coordinate schedules. Anyone connects whenever they want, the base is always there.
• Control the gameplay settings: difficulty, Rupture frequency, resources, passwords. You tailor the experience to your group.
• Server available 24/7 without leaving your PC on (with a dedicated host only). Your base evolves even while you sleep.
• No host dependency. In a classic local session, if the host disconnects, everyone gets kicked. With a dedicated server, players keep playing together.

Concretely, you have 3 ways to play Star Rupture in coop:

We'll detail the last two options, which correspond to real servers.

Method 1 — Create a Star Rupture server via self-hosting

This method is free: you use your own PC as a server. Handy for testing, heavy to maintain day to day.

Prerequisites

Before you dive in, make sure you have:

• A Windows 10/11 PC powerful enough (8 GB of RAM minimum for the server alone, 16 GB if you also want to play on it)
• Steam installed with your Star Rupture account linked
• Admin access to your internet router (to open ports)
• A stable connection with at least 5 Mbps upload
• Patience: first-time configuration takes 30 to 45 minutes

Step 1: Install StarRupture Dedicated Server

The dedicated server is distributed for free by Creepy Jar via Steam. To install it:

1. Open Steam and switch to Library mode
2. In the left sidebar, click the dropdown at the top (usually "Games")
3. Check "Tools" to make Steam tools appear
4. Look for "StarRupture Dedicated Server" in the list
5. Right-click on it, then "Install"

The tool installs in your usual Steam folder (by default C:\Program Files (x86)\Steam\steamapps\common\StarRuptureDedicatedServer).

Step 2: Set up the launch batch file

The server is launched via a .bat file that you have to create. Navigate to the install folder and create a new text file you'll rename start-server.bat. Open it with an editor (Notepad++, VS Code) and paste:

@echo off
StarRuptureServer.exe -ServerName="My RP server" -Port=27015 -Password="password" -MaxPlayers=4
pause

Adjust the settings:

• ServerName: name shown to your friends
• Port: 27015 by default, leave as is unless special case
• Password: access password (leave empty for open server)
• MaxPlayers: 4 maximum, game limit

Save. You can now launch the server by double-clicking this .bat file.

Step 3: Open the ports on the router

This is the step that blocks 90% of beginners. Your server runs on your PC, but without port forwarding, your friends can't connect from outside.

Generic procedure (adapt to your router):

1. Log into your router's interface (often 192.168.1.1)
2. Look for the section "NAT" or "Port forwarding"
3. Create a rule:
   • External port: 27015 (TCP and UDP)
   • Internal port: 27015
   • Destination IP: your PC's local IP (ipconfig command in cmd to find it)
4. Confirm and reboot your router

Also remember to allow the server in your Windows firewall (Windows Defender shows a prompt on first run).

Step 4: Launch the server and grab the IP

Double-click start-server.bat. A console window opens with the boot logs. If everything's OK, you'll see a line like:

[INFO] Server listening on port 27015
[INFO] Steam authentication successful

To get your public IP (the one your friends will use), go to whatismyip.com. This IP looks like 82.123.45.67.

Step 5: Join the server from the game

On the player side:

1. Launch Star Rupture
2. Main menu → "Multiplayer" → "Join by IP"
3. Enter the host's public IP + port (format 82.123.45.67:27015)
4. Enter the password if defined
5. Click "Connect"

You're on your server. Enjoy!

Method 2 — Create a Star Rupture server via a host (recommended)

This method is paid (from €7.99/month at Lordhosting), but it eliminates all the issues of self-hosting. The server runs 24/7 on dedicated infrastructure, with a fixed IP and anti-DDoS protection.

Step 1: Pick your plan

On Lordhosting, three plans are available depending on your needs:

All plans include anti-DDoS, Pterodactyl panel in English, automatic backups and 7/7 support.

Step 2: Deployment in a few clicks

After ordering, your server is provisioned automatically in under 2 minutes. You receive by email:

• The IP and port for connection
• Your credentials to access the Pterodactyl panel
• A link to the web panel: https://game.lordhosting.fr

No Wings to install, no files to upload manually. The server is ready to start.

Step 3: Steam / Steam Guard authentication

Star Rupture requires Steam authentication on the server side to download the game files and validate multiplayer sessions.

From the Pterodactyl panel:

1. "Startup" tab
2. Fill in the variables:
   • Steam Username: your Steam ID (ideally create a dedicated server Steam account)
   • Steam Password: your password
   • Steam Guard Code: if Steam Guard is active, enter the code received by email

The server then downloads the Star Rupture files from Steam (about 8 GB) and runs the configuration. This first setup takes 5 to 10 minutes.

Step 4: Start the server and grab the IP

1. "Console" tab in the panel
2. Click "Start" (green button)
3. Watch the logs: you should see Server is now online after 30 to 60 seconds
4. The IP and port show up in the top banner of the panel (format 82.66.18.xx:27015)

That's the address you'll share with your friends.

Step 5: Create and launch your first session

While you're the server admin, you set up the initial session from the panel or from the game:

• Configuration file: Resources/Server/ServerConfig.txt accessible via the panel's File Manager
• Adjustable settings: session name, difficulty, Rupture frequency, starting resources, map size

Save, restart the server from the console, and the session loads with your settings.

Step 6: Join the server as a player

On the client side (your friends and you):

1. Launch Star Rupture
2. "Multiplayer" menu → "Join by IP"
3. Paste the IP and port provided by the panel
4. Enter the password if you set one
5. Click "Connect"

That's it. You're online.

Advantages of this method

• ✅ Available 24/7, even when your PC is off
• ✅ Fixed IP, no surprise at every restart
• ✅ Technical support available (Discord, tickets)
• ✅ Deployment in minutes, no network configuration
• ✅ Anti-DDoS included, your sessions no longer stop because of outside attacks
• ✅ Pterodactyl panel in English: restart, monitor RAM, read logs in 1 click

Known bugs and solutions

Early access comes with its share of small issues. Here are the most frequent ones and their workarounds.

"More than one server" bug after restart

Symptom: after a server restart, the console shows Error: more than one server running and the server refuses to start.

Solution: this is an orphan Steam process that wasn't killed. On the Pterodactyl panel, run a "Force Stop" from the console, wait 30 seconds, then restart normally. On a self-hosting PC, open the Task Manager and end all StarRuptureServer.exe processes before restarting.

Empty session after restart

Symptom: you restart the server and your base + world seem to have disappeared. You spawn in a fresh session.

Solution: this is a save-loading bug. The save isn't lost, just not selected. Leave the session, then from the Star Rupture main menu, pick "Load session" and choose your most recent save. On a dedicated server, the right save sits in Resources/Saves/ accessible via the panel's File Manager.

IP connection error

Symptom: your friends can't connect, message Connection timed out or Server not responding.

Self-hosting solution: check that ports 27015 TCP and UDP are properly forwarded on your router, and that the Windows firewall allows StarRuptureServer.exe. Test the port with yougetsignal.com/tools/open-ports/.

Host solution: check that you're using the public IP provided by the panel, not the internal IP. If the problem persists, open a support ticket: Lordhosting responds in under 30 min on Discord.
