WebKit main loop freeze with specific urls

On linux or with x32 everything ok. Also build from branch qtwebkit-stable didn't help.

Problem url - https://www.dssl.ru/files/trassir/manual/es/setup-local-server.html
Appear in a simple program:

#include <iostream>

#include <QApplication>
#include <QtWebKitWidgets/QWebView>

int main(int argc, char** argv) {
  if (argc < 2)

  const char* const url_str = argv[1];
  QApplication app(argc, argv);
  QWebView view;
  view.show();
  view.setUrl(QUrl(url_str));
  return app.exec();
}

Checked QNetworkReply from finished signal = `"Unknown error"`
After few minutes program don't respond, see in log
`qt.network.http2: stream 133 finished with error: "HTTP/2 protocol error"`
