HttpHostConnectException ConnectException connection refused ErrnoException

Habe ich ein Netzwerk von Prozessen in meine Anwendung ein, wo diese Ausnahme tritt auf, und ich weiß nicht, wie dieses Problem zu beheben. Ich bereits angewendet, bestimmte Berechtigungen in mein manifest, und hier ist Sie die Berechtigungen habe ich für meine ganzen app:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

und die URI, die ich verwende, ist von unserem server in Ihre Globale IP-Adresse ist bereits. Es funktioniert im browser, aber in der app, diese Ausnahme kommt. Hier ist der stack trace:

Jede Hilfe wird geschätzt. Danke.

EDIT:
Okay, also hier ist mein Programm:

public static String getRequest(String path){
    String url = http://xxx.xx.xxx.xxx:8080/SampleApi/sample-apis; //Global URL of the API
    String username = "sampleuname";
    String password = "samplepass";

    CredentialsProvider credProvider = new BasicCredentialsProvider();
    credProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
            new UsernamePasswordCredentials(username, password));

    try{
        DefaultHttpClient httpClient = new DefaultHttpClient();
        httpClient.setCredentialsProvider(credProvider);
        HttpGet httpGet = new HttpGet(url + path);
        HttpResponse httpResponse = httpClient.execute(httpGet); //Okay, so the stack trace is pointing in this line

        HttpEntity httpEntity = httpResponse.getEntity();
        if(httpEntity != null){ 
            inStream = httpEntity.getContent(); 
            String jsonString = convertStreamToString(inStream);
            return jsonString;
        }
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return "Request NULL";
}

und meine Berufung Asynctask:

public class LoginTask extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... path) {
        Log.d(Constant.TAG_LOGIN, path[0]);

        String apiRequestReturn = Utility.getRequest(path[0]); //So here's the other line pointed by the stack trace where I called Utility
        if (apiRequestReturn.equals("")) {
            Log.d(Constant.TAG_LOGIN, "WebService request is null");
            return null;
        } else {
            Log.d(Constant.TAG_LOGIN, "WebService request has data");
            return apiRequestReturn;
        }
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(null);

        //JSON PARSING
    }
}
