OS / Environment

Windows10

Describe the bug

The downloads do not work under proxy, although Base.download and Downloads.download works just fine. The HTTP_PROXY and HTTPS_PROXY are set properly, ENV["HTTP_PROXY"] = "http://127.0.0.1:3128".

using FastAI

imagenette2_url = "https://s3.amazonaws.com/fast-ai-imageclas/imagenette2-160.tgz"
FastAI.load(datasets()["imagenette2-160"])

Do you want to download the dataset from https://s3.amazonaws.com/fast-ai-imageclas/imagenette2-160.tgz to "D:\z_installed_programs\julia-depot\datadeps\fastai-imagenette2-160"?
[y/n]

Using Downloads.download or Base.download works just fine under the same proxy conditions.

import Downloads
imagenette2_url = "https://s3.amazonaws.com/fast-ai-imageclas/imagenette2-160.tgz"
Downloads.download(imagenette2_url, "imagenette2-160.tgz")

Sorry for the late reply! This seems an issue with your proxy or DataDeps.jl which does the downloading, so unfortunately I can't help you here
