Failed to connect to localhost port 80: Connection refused

Unity WWW class can connect to outside servers, but cannot connect to localhost.
I have a crossdomain.xml in the localhost root.
It is the PHP.EXE built in web server. It does work with other browsers. Unity 5.3.0f4

Can you help me why it doesn’t work?

`
public class AppManager : MonoBehaviour {

public string url = "http://localhost";
public Text Result;
public Text Error;

void Start() {
	StartCoroutine(CallURL());
}

IEnumerator CallURL() {
    WWW www = new WWW(url);
    print("www started");
    yield return www;
    print(www.error);
    print(www.text);
    Result.text = www.text;
    Error.text = www.error;
}

}

After investing six hours into this matter I have the following solution:
It seems PHP.EXE default built in web server is refusing to answer to Unity 3D editor or built EXE files.
One solution is to use EasyPHP or WAMP to start an Apache server and that will give a proper answer to Unity 3D too.
Merry Christmas BTW :slight_smile:

You can use PHP’s built-in web server, but you need to make PHP listen on all interfaces using a command-line argument: -S 0.0.0.0:80
