title: qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method
body: <p>I am trying to make POST request to remote server. Here is my code:</p>
  
  <pre><code>void LoginWindow::on_login_pushButton_clicked()
  {
      const QString url = ui-&gt;server_lineEdit-&gt;text ();
      const QString username = ui-&gt;username_lineEdit-&gt;text ();
      const QString password = ui-&gt;password_lineEdit-&gt;text ();
      QNetworkAccessManager mAccessManager;
      QNetworkRequest request(QUrl(url + "/api/auth/"));
  
      QUrlQuery urlQuery;
      urlQuery.addQueryItem ("username", username);
      urlQuery.addQueryItem ("password", password);
  
      QUrl params;
      params.setQuery (urlQuery);
  
      QNetworkReply* reply = mAccessManager.post (request, params.toEncoded ());
  
      connect (reply, &amp;QNetworkReply::readyRead, [reply]() {
          qDebug()  &lt;&lt; "Ready to read from reply";
      });
      connect (reply, &amp;QNetworkReply::sslErrors, [this] (QList&lt;QSslError&gt; error) {
          qWarning () &lt;&lt; "Ssl error: " &lt;&lt; error;
      });
  
  }
  </code></pre>
  
  <p>When I clicked the login button nothing happens, except a message in application output tab.</p>
  
  <pre><code>qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method
  qt.network.ssl: QSslSocket: cannot resolve SSLv2_server_method
  </code></pre>
  
  <p>I checked the remote server log, there was no request from qt client. </p>
  
  <p>I am using ubuntu 16.04 and Qt 5.9 . I also followed <a href="https://askubuntu.com/questions/711863/installing-qt-5-5-1-on-ubuntu-14-04-throws-qt-network-ssl-error-on-terminal">this</a> solution, still no luck </p>
