Outgoing UDP connection?

Hello,

I would like to connect QGroundControl to Mavproxy. With Mission planner that works fine using UDPCl. With QGroundControl I can’t get it to work:

I checked with tcpdump on the router, I don’t even see it trying to establish a connection.

What am I doing wrong? I understood Connect to UDP server as client · Issue #4228 · mavlink/qgroundcontrol · GitHub that it should work like this.

Thanks
Sebastian
