Write down the complete Rainbow Six Siege error code, then check Ubisoft's service status and your platform's online service. If both are working, restart the game and router, update Rainbow Six Siege, and compare another trusted network. Use the full code, platform, time, and network result when contacting Ubisoft so the error can be matched correctly.
Take a screenshot or write down every part of the connection code. Similar messages can refer to a service outage, platform sign-in, local network, or game update, so the full code matters.
2
Check both online services
Check Rainbow Six Siege's status for your platform, then check PlayStation Network, Xbox network, Steam, or Ubisoft Connect if you use it. Wait when either service reports an incident.
Close the game and launcher completely, restart the PC or console, and sign in again with the account that owns or can access the game. Install any pending game or platform update before testing.
4
Restart the router once
Power the router off, wait about 30 seconds, turn it on, and wait for ordinary internet access to return. Do not factory-reset it or open ports just because one connection attempt failed.
5
Compare another network
Try Ethernet or one trusted mobile hotspot. If the game connects there, the original Wi-Fi, router, or internet provider path is involved. If both networks fail while other services work, stop repeating router changes.
6
Contact Ubisoft with the code
Open Rainbow Six Siege Support and include the full code, platform, country, exact time, and the result from another network. Do not send passwords, two-factor codes, or payment information.
