I am currently experiencing an issue while trying to access my private dataset in my repo  
for example: ([https://huggingface.co/dataset/Mustafa21/dataset](https://huggingface.co/dataset/Mustafa21/dataset))

The error message I encountered is as follows:

```python
ionError(f"Couldn't reach {url} ({repr(head_error)})")
ConnectionError: Couldn't reach https://huggingface.co/datasets/Mustafa21/dataset/resolve/main/dataset_infos.json (ConnectionError('Unauthorized for URL https://huggingface.co/datasets/Mustafa21/dataset/resolve/main/dataset_infos.json. Please use the parameter `use_auth_token=True` after logging in with `huggingface-cli login`'))

```

Thank you in advance for your help!

You must log in as explained [here](https://huggingface.co/docs/huggingface_hub/quick-start#authentication) and then pass `use_auth_token=True` to avoid this error.

PS: Newer `datasets` versions automatically read the token if it’s available in the environment, so the last step is optional.

same problem, even after logging in as indicated  
the HF\_TOKEN environment variable is set too (I try without set)

```auto
 A token is already saved on your machine. Run `huggingface-cli whoami` to get more information or `huggingface-cli logout` if you want to log out.
    Setting a new token will erase the existing one.
    To login, `huggingface_hub` requires a token generated from https://huggingface.co/settings/tokens .
Token can be pasted using 'Right-Click'.
Token:
Add token as git credential? (Y/n)
Token is valid (permission: write).
Your token has been saved in your configured git credential helpers (manager).
Your token has been saved to C:\Users\XXXXXXXX\.cache\huggingface\token
