Qt QSslSocket "The certificate is self-signed and untrusted"

I want to connect to the server with QSslSocket and get soketSslError "The certificate is self-signed and not trusted" on the server, but I don't understand why I have this error.

In the first step, a file was created for the server and client with openssl

$openssl req -new -newkey rsa:1024 -keyout ca.key -x509 -days 500 -out ca.crt
$openssl req -new -newkey rsa:1024 -keyout client01.key -out client01.csr
$openssl ca -config ca.config -in  client01.csr -out client01.crt -batch

      

        
        
        
      

    

in c ++ server / client

On server:

start the server

if (listen(QHostAddress::Any,this->connectingPort)) {
        std::cout<<"Server start on port: "<<this->connectingPort<<std::endl;
        return true;
    } else {
        std::cout<<"Cant start server. "<<errorString().toStdString().c_str()<<std::endl;
        return false;
    }

      

        
        
        
      

    

incomingConnection

    QFile keyFile("ca.key");
    if (!keyFile.open(QIODevice::ReadOnly)) {
        delete this->sslSocket;
        qDebug()<<"Cant open file: "<<keyFile.fileName();
        return false;
    }
    QByteArray pasp ="qwerty";
    QSslKey key(keyFile.readAll(),QSsl::Rsa,QSsl::Pem,QSsl::PrivateKey,pasp);
    if (key.isNull()) {
        delete this->sslSocket;
        qDebug()<<"key in file "<<keyFile.fileName()<<" is empty";
        return false;
    }
    keyFile.close();

    this->sslSocket->setPrivateKey(key);
    this->sslSocket->setPeerVerifyMode(QSslSocket::VerifyPeer);
    this->sslSocket->setLocalCertificate("ca.crt");
    this->sslSocket->startServerEncryption();

      

        
        
        
      

    

on the client side:

this->sslSocket->setPeerVerifyMode(QSslSocket::VerifyPeer);


QFile keyFile("client01.key");

if (!keyFile.open(QIODevice::ReadOnly)) {
    delete this->sslSocket;
    qDebug()<<"Cant open file: "<<keyFile.fileName();
    return ;
}
QByteArray pasp ="qwerty";
QSslKey key(keyFile.readAll(),QSsl::Rsa,QSsl::Pem,QSsl::PrivateKey,pasp);
if (key.isNull()) {
    delete this->sslSocket;
    qDebug()<<"key in file "<<keyFile.fileName()<<" is empty";
    return ;
}
keyFile.close();

this->sslSocket->setPrivateKey(key);

this->sslSocket->setLocalCertificate("client01.crt");

this->sslSocket->connectToHostEncrypted("192.168.0.10",1258);

if (!this->sslSocket->waitForEncrypted()) {
    qDebug()<<"error: "<<sslSocket->errorString();
}

      

        
        
        
      

    

and when i connect to client i get server error

soket ssl error
"The certificate is self-signed, and untrusted" 
"The certificate is self-signed, and untrusted" 
socketError:  QAbstractSocket::SocketError( 13 ) 

      

        
        
        
      

    

any idea what i am doing wrong?
