How can i connect MAVProxy (in server) to QgroundControl (in local)

I need to connect MAVProxy running in my server to QgroundControl in my local, so i tried to do this way:

1. Server side:
- run DroneKit: `dronekit-sitl copter` (by default listen to 5760 port)
- run MAVProxy: `mavproxy.py --quadcopter --master tcp:127.0.0.1:5760 --sitl 127.0.0.1:5501 --out 127.0.0.1:14550 --out 127.0.0.1:14551`
- add my local output to MAVProxy: `output add my_local_ip_addr:14550`

2. Local side:

- Just running Qgroundcontrol (who listen by default to 14550 port).
**But no connexion shown from my QgroundControl.**
- I also tried to send command to my SITL from mavproxy:
`python simple_goto.py --connect udp:my_server_ip_addr:14550`
** But i have a connexion issue **

Start by reproducing the server and local setup with the listed DroneKit SITL, MAVProxy, and QGroundControl commands. Check MAVProxy's master and output endpoints, then verify whether QGroundControl receives traffic on port 14550. Done means the local QGroundControl connection is shown and the simple_goto connection no longer fails.
