Unable to connect to SITL

[DanWilson00]

I have successfully built and run PX4 SITL in Windows 10 Bash and get:
INFO [simulator] Waiting for initial data on UDP port 14560. Please start the flight simulator to proceed..
TCPView confirms that PX4 is connected to localhost and port 14560

I have then done the following:

• Downloaded/installed UE4
• Downloaded/built the dependencies
• Downloaded/built Airsim in VS2015
• Created a new project, added an environment, copied the Airsim plugin files to the project, enabled the plugin
• Modified settings.json to not use serial
• Ran the UE4 project in VS2015 and changed to SimGameMode
• Pressed play

The simulator doesn't connect to the SITL and UE4 hangs until I stop running the project from VS2015 (see below)

Am I missing something?

Modify LocalHostIp to something different than 127.0.0.1, for example 127.0.0.2, that worked for me. Matching IPs makes it use connectLocalUdp which actually starts a server instead of listening, therefore the bind error if the PX4 firmware is already running

That worked, thanks sirluzelot!
