POST request not sending data - fixed

I've been programming in Android Studio for a short amount of time and have been trying to send JSON to an IIS server in a few different ways (Retrofit2, Volley, HttpClient...) but my IIS APP is not getting it right New rows are not introduced in Mysql BBDD.

This method is from my IIS APP which receives a Json, converts it to Object, then makes a query to my BBDD and brings in new rows.

 public String Post([FromBody] Empleado empleado)
    {}

This method works great as I have tried it from an IIS console application and it works fine

Two examples of what I've done in Android Studio:

Volley:

public class MainActivity extends AppCompatActivity {

TextView textView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    enviarDatos();
}

public void enviarDatos(){
    String url ="http://...myurl";
    textView = (TextView)findViewById(R.id.text);

    try {
        RequestQueue requestQueue = Volley.newRequestQueue(this);
        final org.json.JSONObject jsonBody = new org.json.JSONObject();

        jsonBody.put("idTag",112353);
        jsonBody.put("Longitud","1253");
        jsonBody.put("Latitud","Test");

        JsonObjectRequest request = new JsonObjectRequest
                (Request.Method.POST, url, jsonBody, new Response.Listener<JSONObject>() {

                    @Override
                    public void onResponse(JSONObject response) {
                        textView.setText(response.toString());
                    }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        // TODO Auto-generated method stub
                        textView.setText(error.toString());
                    }
                });

        requestQueue.add(request);
    } catch (JSONException e) {
        e.printStackTrace();
    }
}
}

AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />

Any help would be appreciated, thanks for your comment, sorry for my bad english

EDIT: Finally it works! Seems like there was some problem with my URL port, so I changed it and it works fine now.
