How to Join Server
Connecting to your Factorio dedicated server is straightforward. This guide covers both direct connection and server browser methods, plus troubleshooting tips for common connection issues.
Method 1: Direct Connection (Recommended)
Use this method when you know your server's IP address and port:
- Locate your server's IP address and Game Port from your server panel
- Launch Factorio and click Multiplayer from the main menu
- Click Connect to Address
- Enter your server details in the format:
IP:PORT- Example:
123.45.67.89:34197 - For local/LAN servers:
192.168.1.100:34197
- Example:
- Click Connect
Method 2: Server Browser
Public servers appear automatically in the browser if properly configured:
- Click Multiplayer from the main menu
- Click Browse Public Games
- Use the search filter to find your server by name
- Double-click the server to connect
Note: Your server must have visibility-public set to true in server-settings.json to appear in the browser.
Mod Synchronization
Factorio automatically handles mod synchronization when connecting:
- The server will send a list of required mods
- Missing mods download automatically (if available on the mod portal)
- Incompatible client mods are temporarily disabled
- You may need to restart Factorio after mod sync completes
Troubleshooting Connection Issues
Connection Timeout: Verify the server is running and check firewall settings. Ensure ports are open on both server and router.
Mod Mismatch: If mods fail to sync, manually download them from the mod portal and place in your Factorio mods folder.
Version Mismatch: Your Factorio client version must exactly match the server version. Check the server's Factorio version and update your client if needed.
Password Protected: If prompted for a password, contact your server administrator or check your server settings file.
LAN Servers
For local network play:
- Use the server's local IP address (usually starts with 192.168.x.x or 10.x.x.x)
- No port forwarding required for LAN-only access
- Ensure all players are on the same network
