- TCP: 13000, 13005, 13200, 14000, 14001, 14008, 14020, 14021, 14022, 14023, 14024

Advanced PC Solutions: Temporarily disable firewall and antivirus software to test if security applications are blocking Rainbow Six Siege. Add game executables to whitelists. For persistent issues, try DNS changes to Google (8.8.8.8) or Cloudflare (1.1.1.1) DNS servers.
Common Mistake Avoidance: Never forward all ports or disable all security measures permanently. Only make specific changes and revert if ineffective. Document each modification for easy troubleshooting reversal.
Server Status and Advanced Diagnostics
When all local troubleshooting fails, the matchmaking issue likely originates from Ubisoft’s servers. Before making complex network changes, always verify server status.
Monitor Rainbow Six Siege server status through Ubisoft’s official status page, which provides real-time information about global server conditions across all platforms.
The status dashboard displays detailed server health metrics for regional data centers, indicating whether other players are experiencing similar error code 2-0x0000D00A issues simultaneously.
If server status appears normal but problems persist, contact Ubisoft support with detailed troubleshooting information: platform, error code, steps attempted, and network configuration details.
Final Resolution Path: When independent troubleshooting proves ineffective, Ubisoft support can provide platform-specific diagnostics and escalate to network engineering teams for server-side investigation. Maintain detailed notes of all attempted solutions for support efficiency.
