Many Rainbow Six: Siege players report issues with online functions during the game. More specifically, players may experience slow server connections, failed connection attempts or even connection errors.
In this article, we’re going to show how to fix general connection bugs in Tom Clancy’s Rainbow Six: Siege.
How can I fix Rainbow Six: Siege connection errors?
1. Check your firewall/antivirus
One common cause for connection issues in Rainbow Six: Siege can be your antivirus software. Sometimes your antivirus or firewall can block the game from accessing the Internet and cause the network issues to appear.
To fix the problem, you need to be sure that the game is allowed to access the Internet, so add the game to the list of exclusions in your antivirus and firewall.
If that doesn’t work, you might want to try disabling certain antivirus features or completely disable your antivirus.
Some users reported that disabling their antivirus doesn’t solve the problem, and if that’s the case, you might have to uninstall your antivirus.
Once you uninstall the antivirus, check if the issue is still there. If removing the antivirus solves the issue, your next step would be to consider a new antivirus solution.
There are many antivirus software in 2021 that come with integrated game modes. These are specifically created to optimize your gaming while keeping you protected.
Once your antivirus is in game mode, you will not get intrusive notifications, and some non essential functionalities will be paused in order to let you use more resources on the game.
Of course, real-time protection is always on, and all threats are being taken care of as soon as they are detected.
2. Consider using a VPN
Several users reported that they fixed the problem with Rainbow Six: Siege simply by using a VPN like Speedify. According to them, using a VPN solved their connection problems, so you might want to try that as well.
As far as gameplay is concerned, you won’t have to worry about lag spikes, lag, or general disconnections anymore since SPeedify regulates your Internet connection to provide a steadier flow.
Speedify uses a variety of techniques to fix lost and corrupted packets, so match issues with Rainbow Six: Siege will now be a thing of the past.
In fact, all common drawbacks of using VPNs, such as reduced bandwidth, are also something you will not experience while using Speedify.
3. Forward your ports
You will need to forward these ports to your computer’s IP address for the best possible connection:
- Uplay PC:
- TCP: 80, 443, 14000, 14008.

6. Change your server
Many users reported high ping while playing Rainbow Six: Siege. This can be caused because you’re connecting to an automatically picked server.
The server is usually picked based on your ping, and sometimes it might connect you to a server that is far away causing unnecessary lag.
This can be a big problem, but you can fix this issue simply by making changes to a single file. To do that, follow these steps:
- There you should see a list of servers along with their abbreviations.
- Select the server you want, for example wus would be US West, and change the DataCenterHint value accordingly.
- In our example, we would just have to make the following change DataCenterHint=wus and save the file.
After changing the server, start the game again and check if the issue is resolved. For best performance, be sure to select the server that is closest to you.
It’s worth mentioning that you might have to repeat this solution several times in order to successfully change your server.

However, you can easily check if your game files are damaged and repair them right from Steam. Once the process is finished, start the game again and check if the problem is still there.
