Rainbow Six Siege Error 3-0x0001000B: Troubleshooting Guide

The dreaded Error 3-0x0001000B in Rainbow Six Siege can be frustrating, preventing you from connecting to matches. This error typically indicates a problem with your connection to the Ubisoft servers. This guide provides a comprehensive troubleshooting approach to help you get back in the game.

Basic Connectivity Checks

Before diving into advanced solutions, start with these fundamental steps:

• Check Ubisoft Server Status: Visit the official Ubisoft server status page (search "Ubisoft server status" on Google) to see if there are any known outages or maintenance affecting Rainbow Six Siege. If servers are down, the problem isn't on your end, and you'll need to wait.
• Restart Your Router and Modem: Power cycle your networking equipment. Unplug both your router and modem, wait 30 seconds, plug the modem back in, wait for it to fully connect, then plug the router back in.
• Restart Your PC/Console: A simple reboot can often resolve temporary glitches that might be interfering with your connection.
• Check Your Internet Connection: Run a speed test to ensure you have a stable internet connection. Aim for a minimum download speed of 5 Mbps and upload speed of 1 Mbps for a decent experience. Consider contacting your ISP if your speeds are consistently lower.

Advanced Troubleshooting Steps

If the basic checks don't resolve the error, proceed with these more advanced solutions:

1. Verify Game Files: Use the game launcher (Ubisoft Connect or Steam) to verify the integrity of your game files. This will scan for and repair any corrupted or missing files that might be causing connection issues. In Ubisoft Connect, right-click on Rainbow Six Siege, select "Properties," and then "Verify Files."
2. Check Firewall/Antivirus: Your firewall or antivirus software might be blocking Rainbow Six Siege's connection to the servers. Add exceptions for the game's executable files (RainbowSix.exe, RainbowSix_Vulkan.exe if applicable) in your firewall and antivirus settings. The default install location is usually C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games\Rainbow Six Siege.
3. Port Forwarding (Advanced): While not always necessary, port forwarding can sometimes improve connection stability. Forward the following ports for Rainbow Six Siege on your router:
   • UDP: 3658, 6115, 10001, 10002, 10003, 10004, 27015
   • TCP: 80, 443
   Refer to your router's manual for instructions on how to forward ports.
4. Update Network Drivers: Outdated network drivers can cause connection problems. Update your network adapter drivers to the latest version. You can usually find these on your motherboard manufacturer's website.
5. Flush DNS Cache: Open Command Prompt as administrator and type ipconfig /flushdns, then press Enter. This clears your DNS cache, which can sometimes resolve connection issues.
