I can't call ASP.NET Web API from Android over LAN

I have created API service in ASP.NET. I have configured it to make it accessible from another devices in the same LAN. I am sure it works because I am able to visit my website from Android device or emulator. The problem is that I can't call this API from my app in both Android physical device and emulator. I am using "http:\192.168.1.133:2920\api\notes\create" address on device and "http:\10.0.2.2:2920\api\notes\create" on emulator. I have configured also firewall on PC. I know it passes connection because I can execute request from Android web browser. I am sure that the address which I am using in app is 100% correct (I've checked it in debugger). I have also set breakpoint in ASP.NET to see if the action in controller was called, but wasn't. Here is the code from my Android app:

public void sendCommand(final Command command)
    {
        Thread thread = new Thread(new Runnable() {

            @Override
            public void run() {
                try  {
                    HttpURLConnection urlConnection;
                    String data = command.getJson();
                    //Connect
                    urlConnection = (HttpURLConnection) ((new URL(_serverAddress + command.getUri()).openConnection()));
                    urlConnection.setDoOutput(true);
                    urlConnection.setRequestProperty("Content-Type", "application/json");
                    urlConnection.setRequestProperty("Accept", "application/json");
                    urlConnection.setRequestMethod("POST");
                    urlConnection.connect();

                    //Write
                    OutputStream outputStream = urlConnection.getOutputStream();
                    BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
                    writer.write(data);
                    writer.close();
                    outputStream.close();

                    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));

                    String line = null;
                    StringBuilder sb = new StringBuilder();

                    while ((line = bufferedReader.readLine()) != null) {
                        sb.append(line);
                    }

                    bufferedReader.close();

                } catch (Exception e) {
                    e.printStackTrace();
                    Log.e("sendCommand", e.getMessage());
                    return;
                }
            }
        });

        thread.start();
    }

Of course I have added required permissions. Here is my AndroidManifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://ift.tt/nIICcg"
    package="test.notes">

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".NoteActivity"></activity>
    </application>

</manifest>
