Redirect from HTTPS to HTTP at download.qt.io

Unable to download file https://download.qt.io/online/qtsdkrepository/mac_x64/desktop/qt5_5152_src_doc_examples/qt.qt5.5152.examples/5.15.2-0-202011130610qtwinextras-examples-5.15.2.7z from Qt Project repository. Seems that some redirection to HTTP happens which breaks browser policies:
