Satisfactory Server Common Issues & Troubleshooting Guide

​

Connection Issues

​

Players Can’t Connect to Server

• “Failed to connect” errors
• Server not appearing in browser
• Connection timeout during join attempts

​

Check Server Status

1. Verify server is running in control panel
2. Check server console for error messages
3. Confirm startup completed successfully
4. Test local connection first

​

Port Configuration

1. Verify port 7777 is open (UDP)
2. Check beacon port 15000 (UDP)
3. Confirm query port 15777 (UDP)
4. Test port accessibility with online tools

​

Network Troubleshooting

# Test server connectivity
ping your-server-ip
telnet your-server-ip 7777

​

Server Not Showing in Browser

​

Steam Server Registration

• Wait 5-10 minutes for new servers to appear
• Restart server to re-register with Steam
• Check Steam server status at steamstat.us
• Verify beacon port is properly configured

​

Server Configuration

# Ensure proper server settings
[/Script/FactoryGame.FGServerSubsystem]
mServerName=Your Factory Server
mServerDescription=Welcome to our factory!

​

Version Mismatch Errors

​

Client-Server Version Sync

1. Update Satisfactory through Steam
2. Verify game files integrity
3. Check server version with administrator
4. Coordinate updates with all players

​

Performance Problems

​

Factory Lag and Low FPS

• Server FPS below 20-30
• Stuttering during factory operation
• Delayed player actions and building

​

Factory Optimization

1. Reduce active machines - Use power switches for unused areas
2. Simplify belt networks - Avoid complex routing
3. Remove decorative elements - Focus on functionality
4. Implement factory zones - Separate production areas

​

Server Resource Allocation

# Performance optimization settings
[/Script/FactoryGame.FGServerSubsystem]
mAutoPause=True
mAutoSaveInterval=600
mNetworkQuality=3

​

Memory Issues and Crashes

​

Memory Management

1. Increase server RAM allocation (16GB+ recommended)
2. Enable auto-pause when no players online
3. Regular server restarts - Daily during low-activity hours
4. Monitor memory usage trends

​

Save File Optimization

# Clean up save files
# Remove old autosaves
# Compress backup files
# Monitor save file sizes

​

Factory Performance Degradation

• Machines running slowly
• Belt throughput issues
• Power grid instability

​

Production Line Analysis

1. Identify bottlenecks - Check machine efficiency
2. Optimize belt routing - Direct paths preferred
3. Balance power consumption - Add generators as needed
4. Review factory layout - Minimize transport distances

​

Multiplayer Coordination Issues

​

Player Desynchronization

• Players see different factory states
• Building conflicts and overlaps
• Inventory synchronization problems

​

Synchronization Fixes

1. Coordinate building times - Avoid simultaneous construction
2. Regular save/reload - Resync server state
3. Stable connections - Ensure all players have good ping
4. Restart server if desync persists

​

Building Conflicts

​

Conflict Prevention

1. Assign factory zones - Designate areas per player
2. Communication protocols - Use voice chat during building
3. Planning sessions - Coordinate major construction
4. Version control - Save before major changes

​

Resource Management Disputes

​

Resource Coordination

1. Establish resource zones - Designate mining areas
2. Shared storage systems - Central resource hubs
3. Production assignments - Divide manufacturing roles
4. Communication tools - Discord or in-game chat

​

Save File and World Issues

​

Corrupted Save Files

• Server won’t load world
• Missing factory sections
• Player progress lost

​

Save File Recovery

1. Stop server immediately when corruption detected
2. Restore from backup - Use most recent clean save
3. Check save file integrity - Verify file sizes
4. Test world loading before going live

​

Backup Strategy

# Automated backup script example
# Daily backups with rotation
# Test restore procedures
# Multiple backup locations

​

World Generation Problems

​

World Troubleshooting

1. Verify save file compatibility with server version
2. Check world size and complexity
3. Monitor loading times - Large worlds take longer
4. Consider world reset if severely corrupted

​

Mod-Related Issues

​

Mod Compatibility Problems

• Server crashes with mods enabled
• Players can’t connect with different mods
• Factory elements not working properly

​

Mod Synchronization

1. Ensure identical mod lists - All players need same mods
2. Check mod versions - Update to latest compatible versions
3. Test mod combinations - Verify compatibility
4. Remove problematic mods - Identify and disable conflicting mods

​

Mod Performance Impact

​

Mod Optimization

1. Audit installed mods - Remove unnecessary ones
2. Monitor mod performance - Check resource usage
3. Update mods regularly - Latest versions often perform better
4. Use performance-friendly mods - Choose optimized alternatives

​

Update and Maintenance Issues

​

Server Won’t Update

​

Manual Update Process

# Stop server first
# Run SteamCMD update
steamcmd +force_install_dir ./satisfactory_server/ +login anonymous +app_update 1690800 +quit

​

Update Verification

1. Check server version after update
2. Verify file integrity - Ensure complete download
3. Test server startup - Confirm successful update
4. Backup before updates - Always save working configuration

​

Configuration Reset After Updates

​

Configuration Preservation

1. Backup config files before updates
2. Document custom settings for easy restoration
3. Compare configs after updates
4. Restore custom settings if overwritten

​

Factory-Specific Problems

​

Production Line Failures

• Machines not producing items
• Belt flow interruptions
• Resource shortages

​

Production Troubleshooting

1. Check power supply - Ensure adequate power generation
2. Verify resource flow - Trace belt paths for blockages
3. Machine efficiency - Check for overclocking issues
4. Recipe verification - Ensure correct inputs available

​

Belt System Issues

​

Belt Optimization

1. Reduce belt complexity - Simplify routing where possible
2. Check belt capacity - Ensure adequate throughput
3. Monitor item flow - Identify bottlenecks
4. Use smart splitters - Optimize resource distribution

​

Power Grid Problems

​

Power Troubleshooting

1. Calculate power demand - Ensure sufficient generation
2. Check power line connections - Verify grid connectivity
3. Monitor power consumption - Identify high-usage areas
4. Implement power switches - Control factory sections

​
