Rainbow Six Siege Server Connection Error | How to Fix

There is currently a major, widespread outage for Rainbow Six Siege that is likely the cause of your connection error. Do not try to troubleshoot your own internet right now.

The issue is on Ubisoft’s end, and standard fixes (like restarting your router or reinstalling the game) will not work.

⚠️ Critical Update: Security Breach & Server Shutdown

As of December 27–28, 2025, Ubisoft has reportedly taken the Rainbow Six Siege servers offline intentionally.

• The Cause: A massive security breach occurred where hackers were manipulating the game to grant players billions of credits, rare skins, and even arbitrarily banning or unbanning accounts.

• The Response: To stop the damage, Ubisoft has pulled the plug on the servers across all platforms (PC, PlayStation, Xbox).

• Your Account: It is highly recommended that you do not attempt to log in repeatedly while this is happening, to ensure your account data remains safe during the rollback or fix.

How to Check for Updates

Since this is an evolving situation, you should check these official sources before trying to play again:

1. Ubisoft Service Status: Rainbow Six Siege Status Page

2. Twitter/X: Check @UbisoftSupportor@Rainbow6Gamefor real-time announcements.

Standard Troubleshooting (Only for after servers return)

Once Ubisoft confirms the servers are back online, if you still have issues, you can try these standard steps:

1. Verify Game Files:

   • Steam: Right-click game > Properties > Installed Files > “Verify integrity of game files”.

   • Ubisoft Connect: Game properties > “Verify files”.

2. Flush DNS:

   • Open Command Prompt as Admin and type ipconfig /flushdns.

3. Change Data Center:

   • If you are on PC, check your GameSettings.ini file (in Documents/My Games/Rainbow Six - Siege) to ensure DataCenterHint is set to default or your specific region (e.g., playfab/centralindia or playfab/southeastasia depending on your location).
