ejabberd和smack握手失敗了

Question

我在我的雲服務器上運行ejabberd，我認為它運行良好，因為我可以使用pidgin從我的PC連接到它。（ejabberdctl connected-users-number在我連接時回答1，在我離線時回答0。）

現在我嘗試使用smack包從我的android應用程序連接到if，並且我得到IOException：

javax.net.ssl.SSLHandshakeException: Handshake failed

Caused by: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0xb897c858: Failure in SSL library, usually a protocol error
error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (external/openssl/ssl/s23_clnt.c:795 0xacf6bf89:0x00000000)
W/System.err﹕ at com.android.org.conscrypt.NativeCrypto.SSL_do_handshake(Native Method)
W/System.err﹕ at com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:318)

這是我的應用程序代碼：

XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setSecurityMode(ConnectionConfiguration.SecurityMode.required);
config.setConnectTimeout(30000);
config.setUsernameAndPassword(username + "@" + service, password);
config.setServiceName(service);
config.setHost(host);
config.setCompressionEnabled(true);
config.setPort(port);
config.setDebuggerEnabled(true);
config.setSocketFactory(SSLSocketFactory.getDefault());

SmackConfiguration.DEBUG = true;
try {
    TLSUtils.acceptAllCertificates(config);
    XMPPTCPConnection connection = new XMPPTCPConnection(config.build());
    connection.connect();
    connection.login();

} catch (SmackException ex) {
    ex.printStackTrace();
    chatClient.setConnection(null);
} catch(IOException ex){
    ex.printStackTrace();
    chatClient.setConnection(null);                 
} catch ( XMPPException ex){
    ex.printStackTrace();
    chatClient.setConnection(null);                 
}catch (NoSuchAlgorithmException ex) {
    ex.printStackTrace();
    chatClient.setConnection(null);
}catch (KeyManagementException ex) {
    ex.printStackTrace();
    chatClient.setConnection(null);
}
return null;

我真的很感激任何幫助!!

如果服務器中未啟用SSL，請禁用SSL。 要禁用，

config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
