Training problem: bad connection when downloading from ObjaverseXL-sketchfab

Following the dataset's readme file,
I run download.py to download the meshes, after generating the metadata(.csv) for the dataset.
However, the connection always fails after a few downloads.
It might be related to the VPN that I'm using,
But I have no other option cause I live in mainland China.
Is there any way to fix this?

Here is the error log:

Start with dataset_toolkits/download.py and dataset_toolkits/datasets/ObjaverseXL.py, then trace the failing call into objaverse.xl.sketchfab.py shown in the error log. Reproduce the ObjaverseXL Sketchfab download failure and determine a project-supported way for downloads to complete despite the reported SSL connection error; done means the download proceeds without aborting.
