As with all games with an internet connection, Rainbow Six Siege will occasionally experience connection errors. More confusingly, many error codes are a random collection of numbers and letters.
This is the case with Rainbow Six Siege error code 3-0x0001000B, which seems to be preventing players from joining online matches. As it turns out, code 3-0x0001000B has a common cause and a very simple solution.
Rainbow Six Error Code 3-0x0001000B Fix
According to Ubisoft Support, the Rainbow Six error code 3-0x0001000B appears when there is a problem connecting to the Ubisoft servers. This code usually appears along with general connection errors during server downtime or maintenance.
Even if you can't jump into the game, this news is good: error code 3-0x0001000B is a so-called server-side issue. Since everything is fine with your local game client, you don't have to do anything to fix this issue. Instead, you'll just have to wait for Ubisoft to get the servers back up and running.
Any time you experience connection errors, it's worth checking the official Rainbow 6 server status page. There you can see if there are scheduled maintenance or unscheduled outages. If so, you can rule out any issues with your PC or console. Other than that, it might be worth checking out DownDetector, as its user-submitted reports often point to connectivity issues ahead of the official server status pages.
Of course, it cannot be said that error code 3-0x0001000B is always based on server failures. In the event that this code appears outside of scheduled maintenance or downtime, Ubisoft Support recommends that players troubleshoot their internet connection.
If error code 3-0x0001000B is preventing you from joining Rainbow Six, you need to wait until the servers stabilize. There is a high chance of scheduled maintenance or unexpected server failure. Hold on tight and you'll be back in the game before you know it. In the meantime, learn how to upgrade the PS4 version of R6 Siege to PS5.
