How to fix Rainbow Six Siege error code 2-0x0000D00A

Ubisoft’s tactical FPS shooter Rainbow Six Siege has gained a large player base since its release in 2015. However, in its Year 7, Siege still has some glaring connection issues, such as the 2-0x0000D00A error persisting to this day. Here’s how you can fix this error.

You might see various connection issues as a player, such as the ‘Matchmaking Connection Error’ with a code: 2-0x0000D00A or something similar. Ubisoft states that this error means your connection to the matchmaking service timed out or that the connection between you and another player (or several players) could not be established. Many of these connection issues can be caused by broken game files, the game server not working properly, or your router blocking the game’s ports.

However, before starting your own troubleshooting, you should always check Rainbow Six Siege’s official service status page to see if the servers are offline or under maintenance. If you find out everything is going alright there, then you can move on to the next steps to try and fix error code 2-0x0000D00A. (Most of these steps apply to PC users, but console players can also try some of them)

How to fix matchmaking errors in Rainbow Six Siege?

1) Verify The Integrity Of Game Files

If you have purchased the game from Steam/Ubisoft connect, you can easily use this method to verify the game files. So if any files are missing or broken, they will be downloaded from the respective servers. And this fix has been very effective and popular among all PC users.

For Steam:

In your game list, right-click Rainbow Six Siege and select Properties from the context menu. Next, browse to the tab Local Files and click the button ‘Verify Game Files Integrity,’ which will start scanning your game files and automatically fix them for you.

For Ubisoft Connect:

•  Open Ubisoft Connect PC.

•  Go to the Games tab.
•  Select the game.
•  Select Properties on the left-hand side of the game overview.

•  Under Local files, choose Verify files.

•  If prompted, select Repair.

2) Restart your PC/Console and Router

While you may have heard it a lot before, restarting your router and PC/Console can sometimes fix the connection error you are facing. In addition, any software-related bugs or connections from your device to the Ubisoft server might be resolved after restarting.

3) Changing DNS:

Firstly check for your router options— login to your default gateway.
Once you’re in, from the DHCP, add the Google DNS. Then, in the DNS Server tab, configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your primary and secondary DNS servers. Then save and restart your router.

4) Port Forwarding:

Now, we’re going to do some port forwarding. We have some specific ports recommended by the Ubisoft support team.

Below are the ports you need for Rainbow Six Siege:

PC:

TCP: 13000, 13005, 13200, 14000, 14001, 14008, 14020, 14021, 14022, 14023, 14024
UDP: 6015

Console:

  • TCP: 80, 443 (Xbox) | 80, 443, 3478, 3479, 3480 (PS4)
  • UDP: 3074​, 6150, 10000-10099 (Xbox) | 3478, 3479, 3658, 6115, 10000-10099​ (PS4)

To forward port, go to the Forwarding or similar option in your router setting. Now go to Forwarding and then Add new. We need to set up the ports & the ipv4 address one by one. Now select the protocol as UDP. Restart the router after adding all the ports mentioned. Now try the game again; if nothing happens, don’t worry. This setting is still useful for high-performance players. We recommend you keep it this way.

5) DNS Flushing:

Now we’re going to Flush DNS. To do that, all you have to do is press Win+R to open the command prompt. Next, copy or write “ipconfig /flushdns” and hit Enter. You should see the following result of a successful flush.

6) Tweaking Network Settings:

After that, press the Start button and go to the settings. Once we are in, click on Network & Internet and check at the bottom of the list for Data Usage.

Remove the restriction of background data and set that to Never. Next, check the Proxy tab for the ‘Automatically detect settings’ button. If that’s off, turn it on. Next, in ethernet, you can find Change advanced sharing options. From that, turn on network discovery and save changes.

7) Checking Control Panel:

Now search for the Control Panel in the windows search bar. Navigate to Network and Sharing Center. Click on ethernet in the connection type from the Network and hit Properties. Find the IPV4 and select its properties. Next, use the following DNS server addresses.

You can confirm the setting if you want from there. Click ok. Now Flush DNS again as you did earlier. It’s recommended to restart your computer to apply the changes. By this time, your problem should be fixed. You can also reset your router; sometimes, the wrong settings get clogged up. Connecting directly via ethernet rather than through a router is always better.

8) Checking Game Server:


Let’s dive into our game-setting fille. From windows explorer, go to
Documents>My Games>Rainbow Six – Siege

Here you’ll find multiple profiles if you logged in with multiple accounts and ran Siege. First, go to your current game profile. Then, open the file called “GameSettings.ini” with your notepad and hover at the bottom.

Change your DataCenterHint. It could be ‘default’ or another region close to you that the game mistook for the required one. Change default selection to the datacentre of your choosing, then save it from the file & start the game.

Pro Tip:
If you run any antivirus program, use their game mode or restrict checking the game files. Also, try using a VPN to connect to the game. According to many players, using a VPN helped them connect to the servers.

If the above steps didn’t fix your problem, you should contact your ISP and Ubisoft about the issue.
