Street Fighter 6 is an incredibly popular fighting game that has captivated gamers around the world. However, like any other online game, it is not immune to technical issues. One of the most common errors that players encounter is Error Code 40200-21001. If you have been facing this error and are unsure how to fix it, you have come to the right place. In this blog post, we will provide you with a step-by-step guide on troubleshooting this error and getting back into the game.

Check NAT-Type on Windows PC


The first thing you should do when encountering Error Code 40200-21001 is to check your NAT-Type on your Windows PC. If the NAT-Type shows as "Strict," it indicates a connectivity issue that is likely causing the error. Here's how you can troubleshoot it:

  • 1. Log into your router using the Command Prompt. Open the Command Prompt by pressing the Windows key + R, then type "cmd" and press Enter.
  • 2. In the Command Prompt, type "ipconfig" and press Enter. Look for the Default Gateway IP, which will be listed under the Ethernet adapter or Wi-Fi adapter section.
  • 3. Open your preferred web browser and enter the Default Gateway IP into the address bar. This will open your router's settings page.
  • 4. Look for the UPnP (Universal Plug and Play) setting in your router's settings. Enable it if it is disabled. This will allow the game to communicate with the necessary ports and potentially resolve the connectivity issue.

Verify NAT-Type in Xbox Networking App


If you are playing Street Fighter 6 on an Xbox console, you can also check the NAT-Type using the Xbox Networking app. This will help you determine if the port opening is successful. Here's what you need to do:

  • 1. Open the Xbox Networking app on your Xbox console.
  • 2. Check the NAT-Type displayed in the app. If it shows as "Open," it means that the necessary ports are successfully opened, and there should be no connectivity issues related to the game.
  • 3. However, if you encounter Toredo errors, click on the "Fix It" button within the Xbox Networking app. This will attempt to resolve any Toredo-related errors that might be causing the connectivity issue.

Test Connectivity with Friends

After you have followed the above steps to check and potentially fix the NAT-Type and other connectivity issues, it is essential to test the game's connectivity. The best way to do this is by playing the game online with friends. Here's what you should do:

  • 1. Connect with your friends who also play Street Fighter 6.
  • 2. Create a lobby or join a lobby hosted by one of your friends.
  • 3. Play a few matches and monitor whether the NAT-Type remains "Open" and if you can play without encountering any errors. If the NAT-Type remains open, it indicates that the connectivity issue has been successfully resolved.

Troubleshooting for Xbox Users


If you are playing Street Fighter 6 on an Xbox console, there are a few additional troubleshooting steps you can take:

  • 1. Restart your Xbox console. Sometimes, a simple restart can resolve temporary connectivity issues.
  • 2. Check for any pending system updates and install them if available. Updates often include bug fixes and improvements that can resolve known issues.
  • 3. If the error persists, consider resetting your Xbox network settings. To do this, go to the Settings menu, select Network, and choose the "Advanced settings" option. From there, select "Alternate MAC address" and then "Clear." This will reset your network settings, and you will need to set up your network connection again.


Encountering Error Code 40200-21001 in Street Fighter 6 can be frustrating, but by following the troubleshooting steps outlined in this blog post, you should be able to resolve the issue. Remember to check your NAT-Type, enable UPnP in your router's settings, verify the NAT-Type using the Xbox Networking app, test connectivity with friends, and try the additional troubleshooting steps for Xbox users.
