3 min read 01-03-2025

Multiplayer games often present unique challenges. One common frustration in Baldur's Gate 3 (BG3) is encountering the "unable to perform NAT punch 62" error. This prevents you from connecting to your friends or joining online games. This article will guide you through troubleshooting this issue. We'll cover several solutions, so let's get started and get you back to adventuring in the Forgotten Realms!

Understanding the "Unable to Perform NAT Punch 62" Error

The "unable to perform NAT punch 62" error in BG3 signals a problem with your network configuration. NAT (Network Address Translation) is a technique that allows multiple devices on a private network (like your home Wi-Fi) to share a single public IP address. A "NAT punch" is an attempt to directly connect two devices behind NAT firewalls. When this fails (error 62), it means the connection can't be established. This is usually due to firewall restrictions or network configuration issues on either your end or your friend's.

Common Causes and Troubleshooting Steps

Here's a breakdown of the most common reasons for this error and how to address them:

1. Firewall and Router Settings

Check your Firewall: Firewalls often block incoming connections. Temporarily disable your Windows Firewall (or your equivalent macOS firewall) to see if this solves the problem. If it does, you'll need to configure your firewall to allow BG3 through. Look for settings related to "exceptions," "allowed applications," or "ports." You might need to specifically allow UDP and TCP traffic on ports used by BG3. (Note: While disabling your firewall helps diagnose the problem, re-enable it afterward for security reasons.)
Port Forwarding: More permanently, you can forward the necessary ports on your router. This allows incoming connections to reach your computer directly. The specific ports used by BG3 might vary slightly, so consult the game's official support documentation or online forums for the most up-to-date information. Your router's manual will guide you through the port forwarding process.
Router Restart: Sometimes a simple router restart can resolve temporary network glitches. Unplug your router, wait 30 seconds, and plug it back in.

2. Network Configuration Issues

UPnP (Universal Plug and Play): UPnP is a feature that automatically configures your router to forward ports. Ensure UPnP is enabled on your router. Consult your router's manual for instructions on how to enable it.
DMZ (Demilitarized Zone): As a last resort, you can place your computer in the DMZ of your router. This exposes your computer to the internet, so only do this if you've exhausted other options and understand the security implications. Consult your router's manual for instructions.
Check for Network Interference: Wireless interference from other devices can sometimes disrupt connections. Try moving closer to your router or temporarily disabling other devices to see if this improves connectivity.

3. Game and Launcher Issues

Verify Game Files: Corrupted game files can lead to connection issues. Use the game launcher's built-in functionality to verify or repair the game files. This ensures that all game files are intact and up-to-date.
Update Drivers: Outdated network drivers can create problems. Update your network adapter drivers to the latest versions from the manufacturer's website.
Restart Your Computer: A simple restart can often solve minor software glitches affecting your network connection.

4. Friend's Network Configuration

If the problem persists, ask your friend to check their firewall, router settings, and network configuration using the steps above. The problem might lie on their end.

5. Server Issues (Rare)

While less common, server-side issues with BG3 can sometimes cause connection problems. Check the game's official website or social media channels for any announcements of ongoing server maintenance or outages.

Advanced Troubleshooting Steps

If the above steps fail, consider these more advanced options:

Static IP Address: Assign your computer a static IP address within your home network. This can sometimes improve network stability.
Contact Your ISP: If you suspect a problem with your internet service provider (ISP), contact their technical support for assistance.
Consult BG3 Forums: Search the official Larian Studios forums or other reputable gaming communities for discussions regarding the "unable to perform NAT punch 62" error. Other players may have encountered and solved the same issue.

Preventing Future Connection Issues

Keep your software updated: Regularly update your operating system, network drivers, and the game itself.
Monitor your network: Regularly check for network interference or performance issues.
Use a wired connection: A wired Ethernet connection is generally more stable than Wi-Fi, reducing the likelihood of connection problems.

By systematically working through these troubleshooting steps, you should be able to resolve the "unable to perform NAT punch 62" error and rejoin your friends in the world of Baldur's Gate 3. Remember to consult your router's manual for specific instructions on port forwarding and other network settings. Good luck, and happy adventuring!
