Не удается подключиться к локальному серверу XMPP с помощью aSmack

Question

Я пытаюсь подключиться к локальным XMPP сервер (Vysper) из Android App, используя этот код:

// ... 
ConnectionConfiguration connectionConfig = new ConnectionConfiguration("192.168.1.107", 5222); 

// load file from "Pictures" directory from Internal Memory 
File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); 
file.mkdirs(); 
connectionConfig.setSecurityMode(ConnectionConfiguration.SecurityMode.required); 
System.setProperty("javax.net.ssl.trustStore", file + "/clientkeystore"); 

Log.i("Info", file.getAbsolutePath()); 

XMPPConnection connection = new XMPPTCPConnection(connectionConfig); 
SASLAuthentication.supportSASLMechanism("PLAIN", 0); 

connection.connect(); 
//... 

Это трассировки стека:

Я использую aSmack 4.0.6 и Android API 19.

разрешение Android сети и права доступа к файлам был предоставлен:

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

Что не так?

Ваш журнал ошибок говорит, что вы есть Log.e, что пусто, так что проверить, что Log первый:
