The download speed of the software package is abnormal and frequently fails

[x3e5]

In my project, there is only one dependency package 'vibe-d', and the speed of automatically downloading project dependencies using the Dub tool is extremely slow. I have also tried switching to other network environments, but even if I enabled network proxies, it could not be successfully downloaded.

for example

PS E:\Desktop\xxx-demo> dub build
     Fetching vibe-inet 1.1.0 (getting selected version)
Error Failed to download package vibe-inet from  https://code.dlang.org/packages/vibe-inet/1.1.0.zip
