3 min read 03-12-2024

Losing your network connection to a Civ VI host is frustrating. This comprehensive guide will help you diagnose and fix this common issue, getting you back to conquering the world (or at least your friends) in no time. We'll cover the most frequent causes and offer practical solutions.

Common Causes of "Connection to Host Lost" in Civ VI

Several factors can interrupt your connection to a Civilization VI multiplayer game. Let's explore the most common culprits:

1. Network Connectivity Issues

Poor Wi-Fi Signal: A weak or unstable Wi-Fi connection is a primary cause. Try moving closer to your router or connecting via Ethernet for a more stable connection. Interference from other devices can also weaken your signal.
Internet Outages: A temporary outage from your internet service provider (ISP) will obviously sever your connection. Check your internet status with another device.
Firewall or Antivirus Interference: Your firewall or antivirus software might be blocking Civ VI's network traffic. Temporarily disable them to see if this resolves the issue. Remember to re-enable them afterward.
Router Problems: Your router might be malfunctioning, overloaded, or require a reboot. Try restarting your router and modem.
NAT Type: A strict NAT type can prevent connections. Forward the necessary ports for Civ VI in your router settings (details below).

2. Game-Specific Problems

Outdated Game Version: Ensure all players are running the same, up-to-date version of Civ VI. Game updates often include network stability fixes.
Mods and DLC: Conflicting mods or missing DLC can cause connection problems. Try disabling mods or ensuring everyone has the same DLC installed.
Game Bugs: Occasionally, bugs in Civ VI itself can lead to connection drops. Check the official Civ VI forums or Steam Community Hub for known issues and potential workarounds.
Server Issues: Rarely, issues with the game's servers can cause connection problems. Check the 2K Games support site for service status updates.

3. Player-Specific Issues

Background Processes: Other programs consuming significant bandwidth (like streaming or large downloads) can interfere. Close unnecessary applications.
Overloaded Computer: If your computer is struggling to handle the game, this can affect network performance. Close unnecessary programs and consider upgrading your hardware if needed.

Troubleshooting Steps: How to Reconnect to Your Civ VI Game

Let's tackle these problems systematically:

1. Check Your Basic Network Connection

Restart your computer and router: This simple step often resolves temporary glitches.
Test your internet connection: Use a speed test website (like Ookla's Speedtest) to confirm your internet is working correctly.
Connect via Ethernet: If using Wi-Fi, try connecting your computer directly to your router with an Ethernet cable for a more reliable connection.

2. Configure Your Router (Port Forwarding)

Port forwarding can improve your NAT type, allowing for smoother connections. The necessary ports for Civ VI are:

UDP: 27015-27030, 3478, 4380
TCP: 27015-27030

Consult your router's manual for instructions on how to forward these ports. This varies depending on your router's make and model.

3. Investigate Software Conflicts

Temporarily disable your firewall and antivirus: Check if this resolves the issue. If it does, add Civ VI as an exception in your security software.
Check for game updates: Make sure your game is fully updated.
Disable mods: Try playing without mods to see if they're causing the problem.

4. Optimize Your System

Close unnecessary applications: Free up system resources by closing programs you aren't actively using.
Check for background processes: Identify and close anything using significant bandwidth.

5. Seek Community Support

Check online forums: The Civ VI forums and Steam community hubs are great resources for troubleshooting common problems. Search for similar issues and see if others have found solutions.
Contact 2K Support: If all else fails, contact 2K Games support for assistance.

Preventing Future Connection Issues

Maintain a strong internet connection: Upgrade your internet plan if necessary or optimize your home network.
Keep your game updated: Regularly check for updates to ensure optimal performance and stability.
Manage mods carefully: Only use reputable mods and ensure compatibility.
Monitor your system resources: Keep an eye on your computer's performance to prevent overloading.

By following these troubleshooting steps, you should be able to resolve most "connection to host lost" errors in Civilization VI and get back to enjoying the game. Remember to check each step systematically, and don't hesitate to seek help from the online community or 2K support if you're still having trouble.
