Connection error of the HuggingFace's dataset Hub due to SSLError with proxy

### Describe the bug

It's weird. I could not normally  connect  the dataset Hub  of  HuggingFace due to a SSLError in my office. 
Even when I try to connect using my company's proxy address (e.g., http_proxy and https_proxy), 
I'm getting the  SSLError issue. What should I do to download the datanet stored in HuggingFace normally?
I welcome any comments. I think those comments will be helpful to me.

* Dataset address - https://huggingface.co/datasets/moyix/debian_csrc/viewer/moyix--debian_csrc

Steps to reproduce this behavior. 



```
(deepspeed) geunsik-lim@ai02:~/qtlab$ ./test_debian_csrc_dataset.py
Traceback (most recent call last):

(deepspeed) geunsik-lim@ai02:~/qtlab$
(deepspeed) geunsik-lim@ai02:~/qtlab$
(deepspeed) geunsik-lim@ai02:~/qtlab$
(deepspeed) geunsik-lim@ai02:~/qtlab$ cat ./test_debian_csrc_dataset.py
#!/usr/bin/env python
from datasets import load_dataset
dataset = load_dataset("moyix/debian_csrc")

```

1.  Adde proxy address of a company in /etc/profile
2.  Download dataset with load_dataset() function of  datasets package that is provided by HuggingFace.
3.  In this case, the address would be "moyix--debian_csrc".
4.  I get the "`ConnectionError: Couldn't reach 'moyix/debian_csrc' on the Hub (SSLError`)" error message.

### Expected behavior


* error message:
ConnectionError: Couldn't reach 'moyix/debian_csrc' on the Hub (SSLError)
