The first is the connection server code
public static XMPPConnection getXMPPConnection(String server, int port){
try{
// get service connection
ConnectionConfiguration config = new ConnectionConfiguration(server, port);
config.setReconnectionAllowed(true);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setSendPresence(true);
SASLAuthentication.supportSASLMechanism("PLAIN", 0);
//SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);
XMPPConnection connection = new XMPPTCPConnection(config);
connection.connect();
return connection;
}catch (Exception e){
}
return null;
}
then going to log in
XMPPConnection connection = XMPPUtil.getXMPPConnection(loginData.ServerIP);
if(!connection.isAuthenticated() && connection.isConnected()){
connection.login(usrn,pasw);
Presence presence = new Presence(Presence.Type.available);
presence.setMode(Presence.Mode.available);
connection.sendPacket(presence);
DataWarehouse.setXMPPConnection(getApplicationContext(),connection);
}
When connection.login(usrn,pasw) begins run, an exception is thrown

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
