Error Code 3-0x0001b is a connection-related issue in Rainbow Six Siege that prevents players from accessing the game’s servers. It’s worth noting that this error primarily arises due to problems with the game’s servers. These server-related issues can stem from scheduled maintenance or unexpected server outages. While Ubisoft, the developer of Rainbow Six Siege, strives to maintain stable servers, technical glitches and maintenance are inevitable.

Checking the Servers

The first step in resolving Error Code 3-0x0001b is to check the status of the Rainbow Six Siege servers. Before assuming that the error lies within your system, ensure that the servers are operational. Ubisoft often communicates server maintenance schedules through their official channels, such as social media and their website. If the servers are indeed down for maintenance, there’s little you can do other than waiting for the maintenance to conclude. However, if there’s no information about server downtime, the issue might be on your end.

Restart Your Computer

Sometimes, the solution to seemingly complex errors can be as simple as restarting your computer. Rebooting your system can refresh various background processes and clear any temporary glitches that might be causing the connection error. After the restart, launch Rainbow Six Siege again and check if the Error Code 3-0x0001b still persists. If the issue persists, it’s time to move on to the next steps.

Check Your Internet Connection

A stable and robust internet connection is essential for online gaming. Poor connectivity can lead to various errors, including Error Code 3-0x0001b. Perform a speed test to ensure that you have a sufficient download and upload speed for online gaming. If your connection is below the recommended speeds, consider upgrading your plan with your Internet Service Provider (ISP).

Reset Your Network Hardware

Network hardware, such as routers and modems, can sometimes accumulate errors over time that affect connectivity. To address this, perform a soft reset on your router by following these steps:

1. Unplug the power cable from your router.
2. Wait for approximately thirty seconds.
3. Plug the power cable back into the router.

This simple reset can often resolve connectivity issues by clearing out any temporary network glitches. Once the router is back online, check if the error persists.

Switch to a Wired Connection

While Wi-Fi offers convenience, a wired Ethernet connection is more stable for online gaming. Unlike Wi-Fi, a wired connection isn’t susceptible to signal interference or fluctuations. If you’re using Wi-Fi and encountering Error Code 3-0x0001b, consider switching to a wired connection to see if the issue is resolved.

Enable UPnP and Port Forwarding

Universal Plug and Play (UPnP) and port forwarding can help ensure that Rainbow Six Siege’s communication with the servers is seamless. UPnP allows devices on your network to automatically set up port forwarding, while manual port forwarding directs specific network traffic to the appropriate ports. For Rainbow Six Siege, the following ports need to be open:

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

Configuring these settings correctly can potentially resolve connectivity issues.

Reset Host File

Sometimes, the host file on your system can become corrupted or misconfigured, leading to connectivity problems. To reset the host file, follow these steps:

1. Press the Windows key + R to open the Run dialog.
2. Type in “cmd” and press Enter to open the Command Prompt.
3. In the Command Prompt, type “notepad C:\Windows\System32\drivers\etc\hosts” (without quotes) and press Enter.
4. If prompted to choose a program, select Notepad.
5. Delete any lines at the bottom of the file that relate to Rainbow Six Siege.
6. Save the file and close Notepad.

While server-related issues are often the main cause, it’s crucial to ensure that your own system and network are optimized for a seamless gaming experience.
