How to Fix Rainbow Six Siege Error 3-0x0001000B

The Ubisoft support website is of no help at all in regards to error code 3-0x0001000B. All it says is it means you’ve been disconnected, but that’s of little help. It isn’t necessarily true, based on one fix that’s been confirmed to work for some people.

Whatever’s causing the Rainbow Six Siege 3-0x0001000B error for you could be one of a few things. Before launching into full “troubleshooting mode,” though, be sure to check the Siege‘s server status.

How to Check Rainbow Six Siege Server Status

Make sure the game’s servers aren’t going through issues or undergoing maintenance through the official Siege server status page. It’s segmented by platform, and gives breakdowns for connectivity, matchmaking, and authentication.

You should also check out the game on Downdetector just to see if others have been seeing the same problem over the past few hours or days. If everything seems clear on the server status page and Downdetector, it’s time to get cracking on actively trying to fix it.

Error Code 3-0x0001000B Fixes

Clear Out Ubisoft Processes and Relaunch the Game

The first and most basic solution is to exit the game and close out any Ubisoft-related processes, then relaunch it to see if you can connect properly.

  1. Press Ctrl + Alt + Del keys and click “Task Manager.”
  2. Hunt down processes that seem related to the Ubisoft Connect application under “Background processes”.
    • These typically start with the letter “U” and have the Ubisoft logo to the left.
  3. Select any relevant processes and click “End task” to close them.

This solution isn’t a permanent one, but it might do if you don’t frequently get this error. Heck, it might sort it out every time. If you’re getting this error frequently, though, you should probably do a little bit more than close out its processes and relaunch each time.

Reinstall or Verify the Integrity of Rainbow Six Siege’s Game Files

If you’re getting this error on console rather than PC, then reinstalling is the option here. It might be even if you’re playing on PC, but you have another option if you’re running Siege through Steam: verifying its files.

  1. Right-click on Rainbow Six Siege in your Steam library.
  2. Select “Properties.”
  3. Click the “Installed Files” tab.
  4. Click on “Verify integrity of game files” to start.

From here, Steam will check Siege‘s files against its database to confirm that they’re not corrupted or having other issues. If it finds that the game’s files are all in order, this won’t help fix error code 3-0x0001000B.

Restart Your Modem/Router

Primarily you want to restart your modem, but you’ll want to restart your router too for this process. Though you may have a modem/router combo unit. In any case, unplug your modem/router for at least 10 seconds and then plug it/them in again. Once your internet is back up, try to launch Rainbow Six Siege again to see if the error has been fixed.

Update Your Graphics Card Driver

This is the one solution that makes this seem like the 3-0x0001000B error code isn’t necessarily related to your internet connection. It seems silly to recommend it for something that seems like an internet problem, but this has actually worked for some people and it just might for you, too.

Check to see if you’re running the latest GPU driver and download it from either the Nvidia website or AMD website, depending on which sort of graphics card you’re running.
