    I took the example code, and it says so:

    SslEchoClient::SslEchoClient(const QUrl &url, QObject *parent) :
        QObject(parent)
    {
        connect(&m_webSocket, &QWebSocket::connected, this, &SslEchoClient::onConnected);
        connect(&m_webSocket, QOverload<const QList<QSslError>&>::of(&QWebSocket::sslErrors),
                this, &SslEchoClient::onSslErrors);
        m_webSocket.open(QUrl(url));
    }
    

    There are signals and slots, I create an object of this class, but it does not connect. Why?

    You know, there is https://doc.qt.io/qt-5/qwebsocket.html#error-1 signal.
    Did you connect a slot to it to see whether you get an error?

    Also see https://doc.qt.io/qt-5/qwebsocket.html#errorString

      QWebSocket::sslErrors

      why the overload ? as far as I can see sslErrors has no alternatives to QList<QSslErrors>

        Tried to start an example "SslEchoClient", but it irzhe does not connect and does not display error messages.
        In my project I connected the status output to the button:

        #include "mainwindow.h"
        #include "ui_mainwindow.h"
        
        MainWindow::MainWindow(QWidget *parent) :
            QMainWindow(parent),
            ui(new Ui::MainWindow)
        {
            ui->setupUi(this);
        
            myUrl = "wss://ws.binaryws.com/websockets/v3?app_id=xlY2chJRk0XoSL5";
            myWebSocket.open(QUrl(myUrl));
            qDebug()<<myWebSocket.isValid()<<myWebSocket.state();
        
        }
        
        MainWindow::~MainWindow()
        {
            delete ui;
        }
        
        void MainWindow::on_testButton_clicked()
        {
            qDebug()<<myWebSocket.isValid()<<myWebSocket.state()<<myWebSocket.error();
        }
        

        Debug return:
        false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
        false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
        false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
        false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError

        Why can't I even use the example "SslEchoClient" to connect to the websocket?

          @Mikeeeeee DO YOU HAVE ANY ERRORS WHEN TRYING TO CONNECT? After calling myWebSocket.open(QUrl(myUrl).
          Did you connect a slot to https://doc.qt.io/qt-5/qwebsocket.html#error-1 as I suggested?
          Is your onSslErrors called?

            I did, but debag doesn't say it was a error:

                myUrl = "wss://ws.binaryws.com/websockets/v3?app_id=xlY2chJRk0XoSL5";
                myWebSocket.open(QUrl(myUrl));
                //myWebSocket
                qDebug()<<myWebSocket.isValid()<<myWebSocket.state();
                connect(&myWebSocket, QOverload<QAbstractSocket::SocketError>::of(&QWebSocket::error),
                    [=](QAbstractSocket::SocketError error){ qDebug()<<"i have error";});
            

            Example "SslEchoClient" also no message, means no error, but the websocket is not connected.

              Do you have an example of "SslEchoClient" connecting to a websocket?

                Found this code. It is similar to worker.
                You do not know any besoket on which it is possible to check operability?

                  If I use the program with GitHub, I get an error: "WebSocket::processHandshake: Unhandled http status code 301"
                  Please tell me why and how to fix it?

                    @Mikeeeeee If you use Google to search for "http 301" you will find https://en.wikipedia.org/wiki/HTTP_301 which tells you that 301 status code means "Moved Permanently is used for permanent URL redirection". What URL are you using?

                      Trying to connect to websocket "wss://ws.binaries.com/websockets/v3?app_id=1089".
                      Yesterday, he was connected here, and today is not connected.
                      Apparently he works on a certain time.

                        It looks like the bug of websocket. I connect to other web sites.
