Same issue, happened both in beta and Live.
CPU: Intel Core i7-6700K 4 Ghz
GTX: 1070 MSI GAMING X 8GB
Motherboard: Gigabyte
RAM: 16 GB
WAN Fiber 1000/200
Open NAT
Windows 10 x64
The way it's not available at start but is after you start a training/free mode almost makes me think the game is booting up *too* fast before the war assets have a chance to load.
I discovered something. I have an open NAT and opened all portsfrom official website)
Game Ports:
TCP: 443, 80
UDP: 3075, 3074
Uplay PC:
TCP: 80, 443, 14000, 14008, 14020, 14022, 14027, 14028, 14043
and still have factions connection issue, but when i set DMZ on router trouble disappeared.
so I think that I still miss some ports because the DMZ passed everything.
