ValueError: Connection error, and we cannot find the requested files in the cached path
### System Info

transformers version: 4.8.1
python version: 3.8
platform: Ubuntu 20.04.1 LTS

### Who can help?

@ArthurZucker, @younesbelkada

### Information

- [ ] The official example scripts
- [X] My own modified scripts

### Tasks

- [X] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

Just run the below python script
```
from transformers import BertTokenizerFast
tokenizer = BertTokenizerFast.from_pretrained('bert-base-uncased')
```

We can get error messages

```
Traceback (most recent call last):
  File "1.py", line 3, in <module>
    tokenizer = BertTokenizerFast.from_pretrained('bert-base-uncased')
  File "/home/jzwang/miniconda3/envs/torch1.10/lib/python3.8/site-packages/transformers/tokenization_utils_base.py", line 1672, in from_pretrained
    resolved_vocab_files[file_id] = cached_path(
  File "/home/jzwang/miniconda3/envs/torch1.10/lib/python3.8/site-packages/transformers/file_utils.py", line 1329, in cached_path
    output_path = get_from_cache(
  File "/home/jzwang/miniconda3/envs/torch1.10/lib/python3.8/site-packages/transformers/file_utils.py", line 1552, in get_from_cache
    raise ValueError(
ValueError: Connection error, and we cannot find the requested files in the cached path. Please try again or make sure your Internet connection is on.
```

And I tried to download the file in the terminal using `wget https://huggingface.co/bert-base-uncased/blob/main/vocab.txt` but also failed. I do not know if there are any safety policies to prevent access.

I checked the error code which is 104. I guess maybe some services have malfunctioned.

I think it works well before about 2023-07-26 4:00 P.M.

### Expected behavior

Hope you can give me some advice or fix the bug.
Hey! Pretty sure this was just a temporary failure! It is back up for me! <|||||>Thanks for your reply. But the problem still exists for me. 
I debugged the code of Transformers 4.8.1 and found there is an variable called `vocab_files` in PreTrainedTokenizerBase.from_pretrained method.
`vocab_files` contains {'vocab_file': 'https://huggingface.co/bert-base-uncased/resolve/main/vocab.txt', 'tokenizer_file': 'https://huggingface.co/bert-base-uncased/resolve/main/tokenizer.json', 'added_tokens_file': 'https://huggingface.co/bert-base-uncased/resolve/main/added_tokens.json', 'special_tokens_map_file': 'https://huggingface.co/bert-base-uncased/resolve/main/special_tokens_map.json', 'tokenizer_config_file': 'https://huggingface.co/bert-base-uncased/resolve/main/tokenizer_config.json'}. 
But the website `https://huggingface.co/bert-base-uncased/resolve/main/added_tokens.json` and `https://huggingface.co/bert-base-uncased/resolve/main/special_tokens_map.json` show `Entry not found`. I guess it is why the bug appears.<|||||>Pretty sure this has been fixed since then, you should consider using a more recent version of Transformers, 4.8.1 is more than 2 years old.<|||||>Hi!  I encountered the same problem. When reproducing the code of this paper (https://github.com/rshaojimmy/MultiModal-DeepFake), I used the same version 4.8.1 transformers, and executed this line of code

`tokenizer = BertTokenizerFast.from_pretrained(args.text_encoder)` 

prompts such an error: 

`ValueError: Connection error, and we cannot find the requested files in the cached path. Please try again or make sure your Internet connection is on.`

I found it has access this link(https://huggingface.co/bert-base-uncased/resolve/main/vocab.txt) but it returns 404
And I upgraded the version of transformers to 4.10.1 and reported this error:

`requests.exceptions.ConnectionError: (ProtocolError('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')), '(Request ID: 9709381c-b025-435d-aba5-aef8667c4d1a)')
`

I saw [this blog](https://blog.csdn.net/weixin_43301333/article/details/128080461), I guess it's a network problem
