" 1. You are actually using an HTTP proxy, but setting HTTPS_PROXY variable\n"

" 2. You are using Fiddler. Currently a bug (https://github.com/microsoft/vcpkg/issues/17752)\n"
" will set HTTPS_PROXY to `https://fiddler_address:port` which lead to problem 1 above.\n"
" Workaround is open Windows 10 Settings App, and search for Proxy Configuration page,\n"
" Change `http=address:port;https=address:port` to `address`, and fill the port number.\n"
