The dreaded "Unable to Perform NAT Punch 62" error in Baldur's Gate 3 can completely halt your multiplayer experience. This frustrating message prevents you from connecting to online games, leaving you stranded from cooperative adventures. This guide will provide you with various solutions to overcome this obstacle and get back to exploring Faerûn with friends.

Understanding the NAT Punch 62 Error

The "NAT Punch 62" error in BG3 indicates a problem with your Network Address Translation (NAT) settings. Your NAT acts as a gateway between your local network and the internet. This error means the game can't establish the necessary connection between your computer and other players' systems. This is often due to a strict or moderate NAT type.

What Causes NAT Punch 62?

Several factors can contribute to the "Unable to Perform NAT Punch 62" error:

Firewall Restrictions: Your firewall (Windows Firewall, antivirus software) might be blocking the necessary ports for BG3.
Router Configuration: Your router's NAT settings might be overly restrictive, preventing connection establishment.
Network Interference: Other devices or applications on your network might interfere with BG3's connection.
ISP Restrictions: Your internet service provider (ISP) might have restrictions that hinder the game's connectivity.
Outdated Network Drivers: Outdated or corrupted network drivers can cause connection issues.

Troubleshooting Steps for NAT Punch 62 Error

Let's dive into the steps you can take to resolve the "Unable to Perform NAT Punch 62" error:

1. Check Your Firewall and Antivirus Software

Temporarily Disable: Temporarily disable your firewall and antivirus software. Try launching BG3. If it works, you know the issue stems from these programs.
Add Exceptions: If disabling isn't an option, add Baldur's Gate 3 to your firewall and antivirus exceptions list. This allows the game to bypass security restrictions. The specific ports needed might vary, so consult the game's official support documentation or online forums for the exact ports to allow.

2. Configure Your Router Settings

Port Forwarding: Port forwarding allows specific ports to be directed to your computer. Consult your router's manual for instructions on how to forward ports for BG3 (usually UDP and TCP ports).
NAT Type: Check your router's settings to determine your NAT type. Aim for an "Open" NAT type for optimal online gaming. Some routers have options to adjust this.
DMZ: As a last resort, consider placing your computer in the DMZ (Demilitarized Zone). This exposes your computer to the internet, making it more vulnerable. Only do this if other solutions fail, and prioritize security measures afterwards.

3. Examine Your Network Connection

Restart Your Router and Computer: A simple restart often fixes temporary network glitches.
Check for Network Interference: Disconnect other devices from your network to eliminate interference. Close unnecessary applications consuming bandwidth.
Check Your Internet Connection: Ensure you have a stable and working internet connection.

4. Update Your Network Drivers

Device Manager: Go to your Device Manager (search for it in the Windows search bar). Expand the "Network adapters" section, right-click on your network adapter, and select "Update driver."
Manufacturer's Website: Download the latest drivers from your network adapter manufacturer's website.

5. Contact Your ISP

If none of the above steps work, your ISP might be the culprit. Contact your ISP's technical support for assistance. They might be applying restrictions that prevent BG3's connection.

6. Verify Game Files

Steam/GOG/Launcher: Depending on your platform (Steam, GOG, etc.), verify the integrity of your game files. Corrupted game files can cause various connectivity problems. This often involves a built-in option within the platform's game management.

7. Consider Using a VPN

A Virtual Private Network (VPN) can sometimes help bypass network restrictions, allowing for a successful connection. However, this is not always guaranteed.
