Secure connection to the websocket server

[Flysink]

I have a problem with connection through protocol scheme wss, my certificate comodo positivessl
Standard js query:

let socket = new WebSocket("wss://server:port");

error: failed: Error in connection establishment: net::ERR_CERT_COMMON_NAME_INVALID

I also tried:

QList<QSslCertificate> ca = sslConfiguration.caCertificates();
 ca.append(QSslCertificate(byte,QSsl::Pem));
 sslConfiguration.setCaCertificates(ca);

error: in connection establishment: net::ERR_CONNECTION_CLOSED

when i am trying to connect ,on the server there are no errors and signals about connection
and

qDebug() << sslConfiguration.peerCertificate();

here's what happens

QSslCertificate("", "", "922M4Y88sgT3gBhY721Cfc==", (), (), QMap(), QDateTime(Invalid), QDateTime(Invalid))

QSslConfiguration sslConfiguration;
 QFile certFile(QStringLiteral(":/ct/local.crt"));
 QFile keyFile(QStringLiteral(":/ct/local.key"));
 certFile.open(QIODevice::ReadOnly);
 keyFile.open(QIODevice::ReadOnly);
 QSslCertificate certificate(&certFile, QSsl::Pem);
 QSslKey sslKey(&keyFile, QSsl::Rsa, QSsl::Pem);
 sslConfiguration.setPeerVerifyMode(QSslSocket::VerifyNone);
 sslConfiguration.setLocalCertificate(certificate);
 sslConfiguration.setPrivateKey(sslKey);
 sslConfiguration.setProtocol(QSsl::TlsV1SslV3);
 wtServer->setSslConfiguration(sslConfiguration);

objConnect.append(QObject::connect(wtServer, &QWebSocketServer::newConnection, this, &Server::newUser));
objConnect.append(QObject::connect(wtServer, &QWebSocketServer::sslErrors, this, &Server::onSslError));
objConnect.append(QObject::connect(wtServer, &QWebSocketServer::closed, this, &Server::close));

What is the possible cause?
