1. Check if Rainbow Six Siege is down or has other server issues

Ubisoft has an official server status page for Rainbow Six Siege that you can check. If everything is marked as “no issues” then, we need to start applying fixes on your end.

2. Restart the game

If it’s your first time getting the error, then try restarting the game. If this error has happened multiple times already, then, you can skip to the next step, because we do not want to further damage your account with leave penalties.

3. Check your internet connection

The following check-ups are advised:

• Update your Network drivers.
• Turn off your router for 3-5 minutes (unplug it from the power source).
• Firewall / VPN / Antivirus interference: disable them all if you use any of them, for testing purposes. If the error disappears, you need to set exceptions for R6S in your software.
• Test your connection stability on CloudFlare. Jitter is probably the most important part of this test.
• Check if any programs in the background are consuming too much of your Internet speed. Use the Ctrl+Alt+Del keyboard shortcut to reach Task Manager, and in processes, you should sort programs by “Network” which will indicate if there’s anything you ought to turn off before playing Siege again.
• Switch to a cabled connection if you are using WiFi at the moment.
• Change DNS to Cloudflare or Google.

4. Verify the game files and/or reinstall Rainbow Six: Siege

Right-click Rainbow Six: Siege in your Steam Library, go to properties, and there, you will find the “Verify Integrity of Game Files” button that you should click.

Steam will check if there are any damaged or corrupted files and will replace them with new ones for you.

If this fails as well, just reinstall the game. Yes, yes, I know, it’s a huge download.
