HTTPS request error while using network proxy

Mozzie

hi,
I want to analyze https stream data. I create a proxy server by QTcpServer and QSslSocket, but after I set up proxy to my server and request www.example.com, I got ssl error:

	m_networkManager = new QNetworkAccessManager(this);
	QNetworkProxy proxy(QNetworkProxy::HttpProxy);
	proxy.setHostName(proxyHost);
	proxy.setPort(9999);
	m_networkManager->setProxy(proxy);

	QNetworkConfiguration networkConfiguration = m_networkManager->configuration();
	networkConfiguration.setConnectTimeout(3000);

	m_networkManager->setConfiguration(networkConfiguration);

	connect(m_networkManager, &QNetworkAccessManager::sslErrors,
			this, [this](QNetworkReply *reply, const QList<QSslError> &errors){

		qDebug() << reply << errors;
	});

QNetworkReplyHttpImpl(0x19b6e5ff990) ("The host name did not match any of the valid hosts for this certificate")

my certificate is created by openssl:

openssl genrsa -out privkey.pem 2048 
openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095 -config openssl.cnf

what does 'The host name' and the 'the valid hosts' means? and where can I find it or change it?

thank you so much!

Hi,

When you create a certificate you have to give informations like for which host it will be valid. From the looks of it, you did not do that.

@SGaist

thank you.
I am just confused about which host should match the host of the certificate i created when I use network proxy.
there is two host, one is proxy server host, and the other is the host I actually need to connect.

Usually the final target. Then it depends on your proxy.
