@bahram1 Hi, I have something new to share with you(about tor). If you want to know how to renew ip of tor, please check this get-new-ip-of-tor7-0-by-standard-python-socket-only.
If you want to know how to do it by Qt5, check the source codes of QImageScraper. Since this is an app with ui, I do not use synchronous network api at all.
