the Default Base URL for netboot images is "http://deb.debian.org/debian/dists/stable/", currently it's Debian 10 (Buster)
if I change the the Base URL for netboot images to "http://deb.debian.org/debian/dists/Debian9.9/", it's all ok and no this error.
I have tried win32-loader 0.9.4 and 0.9.5, both are have this issue.
win32-loader 0.9.4 http://ftp.debian.org/debian/tools/win32-loader/stable/win32-loader.exe
win32-loader 0.9.5 http://ftp.debian.org/debian/tools/win32-loader/unstable/win32-loader.exe
