It seems you may be having some connection issues to the Uplay servers. Please try the steps below to see if your connectivity issues resolve.
1. Internet Connection Sharing (ICS) and Virtual Private Networking (VPN) applications can also be conflicting with the game, and you will want to disable these applications to try to resolve the issue.
2. Port Forwarding
If it is not possible to shut-down your firewall you will need to configure your router and/or firewall to forward the following network ports:
Uplay
TCP: 80, 443, 13000, 13005, 13200, 14000, 14001, 14008
R6: Siege
UDP: 10000-10099, 3074, 3658
TCP: 80, 443
(Directions for configuring network ports are specific to the software and hardware being used, and can be found by visiting the manufacturer's website. Websites such as
http://www.portforward.com offer tutorials on how to open ports on your router.)
If these steps do not assist with the issues you are experiencing, please contact our Ubisoft Support for further assistance. Thank you!
