Depending what Qt version is used to build IFW, system proxy might be on by default. If built with Qt5.8 or less, no system proxy is used by default if '--proxy' not passed from command line. As from Qt5.8 onwards system proxy is used by default, add option --no-proxy to enable installer usage without proxy.
