1. Switch to the game server that’s closest to you

The error code 3-0x0001000B in Rainbow Six Siege is usually related to network connection, especially when the server you’re connected to is very far from that of Ubisoft. To see if this is a problem for you, you can do the following to switch the server you connect to in Rainbow Six Siege manually:

4. Then press the Ctrl and the S keys on your keyboard to save the change.

Try Rainbow Six Siege again to see if the error code 3-0x0001000B persists. If so, please move on.

2. Try the Google DNS instead of the default one

As mentioned, the error code 3-0x0001000B in Rainbow Six Siege could relate to your network connection, especially if the default DNS server provided by your ISP (Internet Service Provider) is not stable enough. In that case, we’d suggest you first flush the DNS cache, and then switch to the default DNS server from Google.

To do so:

1: Flush your DNS

By flushing your DNS, your DNS cache will be cleared. When your PC needs to access a website, it’ll need to obtain the address from the DNS server again. This may fix the error code 3-0x0001000B in Rainbow Six Siege if the DNS cache data is invalid or corrupt. Here’s how:

1. Press the Windows logo key and R on your keyboard to invoke the Run box.
2. Type cmd, then press Shift and Enter at the same time. If prompted for permission, click Yes.
   
3. Copy ipconfig /flushdns, and paste it in the pop-up window. Then press Enter.
   
4. Your DNS cache is successfully cleared.
   

2: Switch to a public DNS server

Then use the Google DNS server instead:

1. On your taskbar, right-click the network icon, then click Open Network & Internet settings.
   
2. Click Change adapter options.
   
3. Right-click the network you’re using, then click Properties.
   
4. Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
   
5. Select Use the following DNS server addresses, fill in the Google DNS server addresses as below, then click OK.
   
   Preferred DNS server: 8.8.8.8
   Alternate DNS server: 8.8.4.4
   
   

When the above changes are made, launch Rainbow Six Siege again to see if the error code 3-0x0001000B remains. If so, please move on.

3. Disable possible conflicting programs

Steam, Ubisoft, and Epci Games Launcher can be a bit sensitive about certain programs running in the background. Here’s a list of software that could most likely cause the error code 3-0x0001000B in Rainbow Six Siege:

• MSI Afterburner
