Problem connecting to SITL (MavProxy, MissionPlanner)

[copter_pro]

Hi,

I successfully launch SITL, even managed to control it via Android tablet.
However, I fail to connect to it via local app like MavProxy or MissionPlanner.

In MavProxy I enter "mavproxy.exe --master tcp:127.0.0.1:5760"
Error response: "Failed to connect to tcp:127.0.0.1:5760 : [Errno 10061]" which means that SITL rejected connection.

In MissionPlanner via TCP I got same error, UDP hangs forever

I also tried MissionPlanner 1.2.90 - same result.

Win 7RC1
Vagrant 1.8
ArduCopter 3.4-dev <a1f151a7>
Mission Planner 1.3.39
MavProxy 1.5
