QNetworkAccessManager 是否支持 HTTPS 代理？

Question

I compiled OpenSSL on my Windows machine 并且能够使用 QNetworkAccessManager 进行 HTTPS 查询，但是当我尝试添加 HTTPS 代理时

QNetworkAccessManager m_nm;
connect(&m_nm, &QNetworkAccessManager::proxyAuthenticationRequired, this, &BinanceReceiver::onProxyAuthenticationRequired);
connect(&m_nm, &QNetworkAccessManager::sslErrors, this, &BinanceReceiver::onSslErrors);

QNetworkProxy m_proxy(QNetworkProxy::HttpProxy, "host.com", 3129, "user", "password");
m_nm.setProxy(m_proxy);

QNetworkRequest request;
request.setUrl(MakeUrl(url));
QNetworkReply* reply = m_nm.get(request);

QObject::connect(reply, &QNetworkReply::finished, [this, reply]()
{
    if (reply->error())
    {
        netLogger.error(reply->errorString());
    }
    else
    {
        //...
    }

    //Ensure it is deleted after this handler is called, but not before.
    delete reply;
});

它停止工作，我根本没有收到回复，也没有触发 proxyAuthenticationRequired 和 sslErrors。

它是一个带有身份验证的 Squid HTTPS 代理。
