Rainbow Six Siege won't connect to servers
Outage, router or software conflict
When Siege can't reach its online services, Ubisoft says the cause can be your internet provider, how your connection is shared, or software on your PC getting in the way.
How to fix it
Check Ubisoft Help for maintenance or an outage on Siege.
Turn off your router, unplug it for at least 60 seconds, then turn it back on.
Update Windows so your network drivers are current.
Do a clean boot so only essential services run.
Turn off any VPN or proxy, and test on a wired connection if you can.
