Rainbow Six Siege Server Connection Error | R6 Server Outage

December 8, 2025 Freddy Error Fix 0

“Rainbow Six Siege” connection errors can be frustrating as they often leave you where you are when trying to join a match. The reason usually varies from Ubisoft’s servers being down to problems with local network configuration.

Here is a step-by-step troubleshooting guide, starting with the easiest checks.

1. First: Eliminate server outages

Before troubleshooting your own equipment, make sure Ubisoft isn’t having a bad day.

  • Official Status Page: Check the Ubisoft Service Status page.

  • Community Status: Check Downdetector or the R6Fix site to see if other players are reporting spikes in outages.

  • Twitter/X: Check @UbisoftSupport for real-time announcements.

2. Immediate “Quick Fixes”

If the servers are green (operational), try these rapid solutions:

  • Restart the Game & Launcher: Fully close Siege and Ubisoft Connect (or Steam/Epic).

  • Restart Your Router: Unplug your router for 60 seconds and plug it back in. This clears the cache and establishes a fresh connection to your ISP.

  • Switch to Wired: If you are on Wi-Fi, test with an Ethernet cable. Siege is notoriously sensitive to the micro-packet loss that happens on Wi-Fi.

3. Identify Your Error Code

Different codes point to different problems. Common ones include:

  • Error 3-0x0001000B: This is the most common connection error. It usually means the game cannot reach the primary servers.

    • Fix: Verify game files (see below) or try changing your LAN settings.

  • Error 6-0x00001000: The connection to the matchmaking service timed out.

    • Fix: Usually a server-side load issue. Restarting the queue or the game often fixes it.

  • Error 4-0xFFF0BE25: A failure to join the party/squad.

    • Fix: Everyone in the squad needs to restart their game.

4. Platform-Specific Troubleshooting

For PC Users

  • Verify Game Files:

    • Steam: Right-click Siege in Library > Properties > Installed Files > Verify integrity of game files.

    • Ubisoft Connect: Select the game > Properties > Verify files.

  • Flush DNS:

    1. Press Windows Key + R, type cmd, and press Enter.

    2. Type ipconfig /flushdns and hit Enter.

  • Check Background Apps: Background applications like VPNs, VoIP software, or torrents can trigger Siege’s anti-cheat or flood the connection. Disable them temporarily.

For Console Users (PlayStation/Xbox)

  • Power Cycle: Turn off the console completely (do not just put it in rest mode). Unplug the power cord for 2 minutes, then restart.

  • Check NAT Type: Go to your console’s network settings. You want your NAT type to be Open (Type 1 or 2). If it is Strict (Type 3), you will struggle to connect to servers and other players.

    • Fix: Enable UPnP on your router settings if you are comfortable accessing them.

5. Advanced Fix: Change DNS Servers

If you still can’t connect, your ISP’s lookup server might be struggling to find Ubisoft’s addresses. Try switching to a public DNS:

  1. Go to your Network Settings (on PC or Console).

  2. Select Manual DNS setup.

  3. Enter the following (Google DNS):

    • Primary: 8.8.8.8

    • Secondary: 8.8.4.4

If you are getting a specific error code that isn’t listed here, let me know the code (e.g., 2-0x0000C015) and I can look up the exact fix for that variation.
