The “NAT-Punch 66” error typically relates to network issues that prevent a game from establishing a stable connection. This can be due to several factors, including your network configuration, firewall settings, or issues with the game’s servers.

Common Causes

  1. Network Configuration: The error might arise from how your network is set up, particularly if Network Address Translation (NAT) settings are too strict.
  2. Firewall Settings: Firewalls can block the necessary ports that Baldur’s Gate 3 requires for online play.

Adjust Firewall Settings

  1. Allow the Game Through Firewall: Ensure that your firewall allows Baldur’s Gate 3 to communicate through both private and public networks.

Optimize Network Settings

  1. Use a Wired Connection: If possible, use a wired connection instead of Wi-Fi for a more stable connection.
