Fix Timeout Error

__Outdated Guide as of Release of Satisfactory 1.0__

Satisfactory currently has a known bug where the server times out. Here are a few steps to help fix this issue:

Legacy Timeout Error Analysis

Historical context for pre-1.0 Satisfactory networking issues (may not apply to current game):

Historical Timeout Causes

• Network Timeout: Connection between client and server interrupted or too slow
• Server Response: Server took too long to respond to client requests
• Configuration Issues: Network settings not optimized for connection type
• Hardware Limitations: Server or client hardware couldn't handle connection load
• Mod Conflicts: Some mods introduced network latency issues

Client-Side Network Optimization

Accessing Configuration Files

Modify your local game configuration to improve network stability:

1. Locate Config Directory:
• Steam: %LOCALAPPDATA%/FactoryGame/Saved/Config/Windows/
• Epic Games: %LOCALAPPDATA%/FactoryGame/Saved/Config/Windows/
• Alternative Method: Press Win + R, paste the path, and press Enter.
2. Backup Files: Always backup configuration files before modifying them.
3. Edit with Caution: Incorrect settings can prevent game from starting.

Engine.ini Modifications

Open Engine.ini and locate [/Script/OnlineSubsystemUtils.IpNetDriver] section:

[/Script/OnlineSubsystemUtils.IpNetDriver]
MaxClientRate=120000
MaxInternetClientRate=120000
InitialConnectTimeout=300.0
ConnectionTimeout=300.0

Parameter Explanations

• MaxClientRate: Maximum bandwidth for local network (120000 recommended).
• MaxInternetClientRate: Maximum bandwidth for internet connections (120000 recommended).
• InitialConnectTimeout: Time in seconds before initial connection attempt fails (300 seconds = 5 minutes).
• ConnectionTimeout: Time in seconds before established connection is considered lost (300 seconds = 5 minutes).

Game.ini Network Settings

Open Game.ini and add or modify [/Script/Engine.GameNetworkManager] section:

[/Script/Engine.GameNetworkManager]
TotalNetBandwidth=104857600
MaxDynamicBandwidth=104857600
MinDynamicBandwidth=10485760

Bandwidth Configuration

• TotalNetBandwidth: Total network capacity in bytes/second (104857600 = 100 MB/s = 1 Gbps).
• MaxDynamicBandwidth: Maximum dynamic bandwidth allocation.
• MinDynamicBandwidth: Minimum bandwidth allocation for stable connection.
• Adjustment: Lower values for slower connections, higher values for gigabit networks.

Scalability.ini Network Quality

Open Scalability.ini and modify [NetworkQuality@3] section:

[NetworkQuality@3]
TotalNetBandwidth=104857600
MaxDynamicBandwidth=104857600
MinDynamicBandwidth=10485760

Quality Settings

• Network Quality Level: Adjust based on connection stability (1-5 scale).
• Bandwidth Consistency: Higher values provide smoother gameplay but use more data.
• Latency Tolerance: Higher tolerance for unstable connections, lower for fast stable networks.

Server-Side Optimization

Dedicated Server Configuration

• Tick Rate: Set server tick rate to 120 for smooth gameplay.
• Timeout Values: Increase timeout values for players with slower connections.
• Bandwidth Limits: Set appropriate bandwidth limits per player.
• Network Quality: Configure server network quality to match average player connection.

Server Command Line Options

• Multihome: -multihome=IP_ADDRESS (Use carefully, can cause API issues in 1.0).
• Port Configuration: Ensure Port 7777 is properly forwarded.
• Max Players: Set appropriate player limit for server hardware.
• Log Level: Increase logging for debugging timeout issues.

Common Timeout Scenarios

Connection Timeout During Load

• Symptom: Timeout when server has many players or large factories.
• Cause: Server CPU or network cannot handle load.
• Solution:
• Reduce player count or factory complexity.
• Increase timeout values in configuration files.
• Upgrade server hardware if necessary.
• Reduce mod count, especially performance-heavy mods.

Timeout on Startup

• Symptom: Server fails to respond to initial connection attempts.
• Cause: Server hardware insufficient or configuration issues.
• Solution:
• Check server logs for specific error messages.
• Verify server meets minimum hardware requirements.
• Check for corrupted save files.
• Restart server service/application.
• Review recent server configuration changes.

Timeout During Gameplay

• Symptom: Disconnection during active gameplay despite good connection.
• Cause: Network instability or client configuration issues.
• Solution:
• Verify client configuration files are correct.
• Check internet connection stability.
• Disable VPNs or proxies that may interfere.
• Close bandwidth-intensive applications.
• Test with different network connection if available.

Advanced Troubleshooting

Diagnostic Commands

• Network Test: Run ping and traceroute to server to identify network issues.
• Port Check: Verify Port 7777 is accessible from your location.
• Bandwidth Test: Test available bandwidth to server location.
• Firewall Verification: Confirm no firewall is blocking connections.

Mod-Specific Timeout Issues

• Mod Conflicts: Some mods introduce network latency or timeout issues.
• SML (Satisfactory Mod Loader): Ensure SML is updated to latest version.
• Mod Dependencies: Verify all mod dependencies are installed and compatible.
• Performance Mods: Some mods significantly increase server load and network traffic.
• Mod Removal: Test vanilla (no mods) to isolate mod-related timeout issues.

Network Environment Issues

• ISP Throttling: Some ISPs throttle continuous connections.
• Network Congestion: High-traffic periods may cause timeouts.
• Router Configuration: Quality of Service (QoS) settings may interfere.
• WiFi Interference: Use wired connection when possible for stability.
• VPN/Proxy: These can introduce additional latency and timeout issues.

Best Prevention Practices

Regular Maintenance

• Server Restarts: Schedule regular restarts to clear memory and network issues.
• Configuration Reviews: Regularly review and update network settings.
• Mod Updates: Keep all mods updated to latest compatible versions.
• Performance Monitoring: Monitor server performance metrics for developing issues.

Configuration Optimization

• Balanced Settings: Choose settings appropriate for your connection type.
• Conservative Timeouts: Use longer timeout values for stability.
• Appropriate Bandwidth: Set bandwidth based on actual network capacity.
• Regular Testing: Test connections after configuration changes.

Transition to Satisfactory 1.0

In September 2024, Satisfactory 1.0 introduced major networking changes that obsolete most of the information in this historical guide:

• Port Changes: Port 7777 replaced old ports (15777, 15000) as the primary connection port
• TLS Encryption: New authentication system replaced basic token-based auth
• In-Game Server Manager: Dedicated servers now use integrated in-game management instead of external tools
• EOS Authentication: Epic Online Services integration for secure player identity

When to Use This Historical Guide

This legacy information may still be useful in these specific scenarios:

• Early Access Servers: Running older pre-1.0 dedicated servers with original networking model
• Single-Player Testing: Testing connection configurations in single-player mode
• Understanding Changes: Learning how pre-1.0 differed from 1.0 for educational purposes
• Legacy Systems: Maintaining or troubleshooting older hardware/software configurations
