QSslSocket can not receive readyRead single

Same implementation file, Classes created by multiple threads will fail.  

bytesAvailable return 0

Use the entire class for TLS validation， my code client.

connect(&server, SIGNAL(connected()), this, SLOT(connectedToHost()));

connect(&server, SIGNAL(disconnected()), this, SLOT(serverDisconnect()));

connect(&server, SIGNAL(readyRead()), this, SLOT(readData()));

connect(&server, SIGNAL(sslErrors(QList<QSslError>)), this, SLOT(sslErrors(QList<QSslError>)));

server.setPrivateKey("certificates/client.key");

server.setLocalCertificate("certificates/client.crt"); server.setPeerVerifyMode(QSslSocket::VerifyNone); server.setProtocol(QSsl::TlsV1_2);

The ReadyRead error code cannot be received, the Success code can be received, and other signals can be received in both codes.

Wireshark receives a message packet from the server.

error code:

QCoreApplication a(argc, argv);

QtConcurrent::run([](){ Link link; link.connectToServer(); QThread::sleep(3); }); 

return a.exec();

success code:

QCoreApplication a(argc, argv); Link link; link.connectToServer(); return a.exec();
