I can't connect ardupilot plane. "Mavlink Connecting..."

I downloaded the mission planner simulation and set up the sitl. After doing all the operations correctly, I started the coatcopter.
But I want to open mission planner with plane but I am having a connection problem.

first I write the following command for the connection.

dronekit-sitl plane-3.3.0 --home=-35.363261,149.165230,584,353

Then I try to connect over mavproxy with the command below, but the “mavlink connecting …” warning is always displayed and it is not connected. --master tcp: --sitl --out --out

I ran the same code above on the coatcopter. In the meantime, the Mission Planner application is connected as UDP and 57600.

Where am I making a mistake please can you help?

You are better off compiling the SITL yourself. And you should decide if you want to use plane or copter. You mention plane in the commands and on the text but you also talk about copter and you posted on a copter thread.

What is it Plane or Copter???
And please update to 4.0.7 or 4.0.9
