QtSsl 出现the remote host closed connection 问题

刚开始学QtSsl 一直找不到什么例子 好不容易看到个 问题是 运行的时候 Client出现了the remote host closed connection的问题 代码如下：
ClientExample::ClientExample(QObject *parent):
QObject(parent)
{

}

void ClientExample::run()
{
QString hostName = ""127.0.0.1"";
quint16 port = 23333;

QByteArray cert;QSslSocket client_socket;QFile file_cert(""c:\Ssl\bin\servercert.pem"");if(file_cert.open(QIODevice::ReadOnly)){    qDebug()<<""Cert is Ok"";    cert = file_cert.readAll();    file_cert.close();}else{    qDebug()<<file_cert.errorString();}QSslCertificate ssl_cert(cert);client_socket.addCaCertificate(ssl_cert);client_socket.connectToHostEncrypted(hostName port);qDebug()<<""Client has connect the IP""<<hostName<<port;if(client_socket.waitForEncrypted(-1)){    qDebug()<<""Connected"";    client_socket.write(""Hello World!"");    if(client_socket.waitForBytesWritten(-1))        qDebug()<<""Message sent"";    else        qDebug().nospace()<<""Error: Coulen't send message (""<<qPrintable(client_socket.errorString())<<"")"";    while(!client_socket.waitForDisconnected()){        QThread::msleep(10);        qDebug()<<""Disconnected"";    }}else{    qDebug().nospace()<<""Error: Couldn't not establish encrypted connection (""<<qPrintable(client_socket.errorString())<<"")"";}this->deleteLater();QThread::currentThread()->quit();qApp->exit();

}

解决方案

你发起的连接，被server拒绝了，是否允许你连接

解决方案二：
才发现 例题的server里面 加了个 QMAKE_CXXFLAGS += -std=c++11......
