Frequently Asked Questions

What does Rainbow Six Siege error code 6-0x00001000 mean?
Error 6-0x00001000 in Rainbow Six Siege means your game client timed out while trying to connect to Ubisoft's servers. It is most commonly caused by a server outage, an unstable internet connection, a firewall blocking the game, or corrupted game files.
Is error 6-0x00001000 on Ubisoft's side or mine?
It can be either. Start by checking the official Ubisoft server status page or Downdetector for Rainbow Six Siege. If widespread outages are reported, the problem is on Ubisoft's end and you need to wait. If servers are healthy, the issue is likely with your local network or game installation.
How do I fix error 6-0x00001000 on PlayStation or Xbox?
On consoles, restart the game and console, restart your router, switch to a wired Ethernet connection if possible, and manually set your DNS to 8.8.8.8 and 8.8.4.4 in your console's network settings. Also make sure your console's NAT type is set to Open or Type 2 for the best connectivity.
Will reinstalling Rainbow Six Siege delete my progress or unlocks?
No. Your operator unlocks, rank, and account progress are all saved on Ubisoft's servers and tied to your Ubisoft account. Reinstalling the game will not affect your in-game progress. You may need to reconfigure local settings or keybindings after reinstalling.
Why does error 6-0x00001000 keep coming back even after fixing it?
If this error returns repeatedly, it usually points to persistent network instability such as packet loss on your internet connection, a failing router, or ongoing issues with your ISP. Try running a packet loss test and contacting your ISP if you see consistent drops. Also check that your router firmware is up to date and that your connection hardware is functioning properly.
