Sudden urllib.error.HTTPError: HTTP Error 404: Not Found after many successful executions

Hi!

I had my Dash application working smoothly, when all of the sudden (without making any changes in code), The following error occurs and the app crashes:

 File "index.py", line 7, in <module>
    from layouts import lecture_43, noPage
  File "C:\Users\PC04\Documents\gdp-quant-academy\layouts.py", line 9, in <module>
    from lecture43 import lecture_43
  File "C:\Users\PC04\Documents\gdp-quant-academy\lecture43.py", line 77, in <module>
    datetime(t_end.year, t_end.month, t_end.day, 21, 0).timestamp())},
  File "C:\Users\PC04\Documents\gdp-quant-academy\lecture43.py", line 53, in real_data_from_ticker
    real_data = pd.read_csv(query)
  File "C:\Users\PC04\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 702, in parser_f
    return _read(filepath_or_buffer, kwds)
  File "C:\Users\PC04\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 413, in _read
    filepath_or_buffer, encoding, compression)
  File "C:\Users\PC04\Anaconda3\lib\site-packages\pandas\io\common.py", line 202, in get_filepath_or_buffer
    req = _urlopen(filepath_or_buffer)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 531, in open
    response = meth(req, response)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 641, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 569, in error
    return self._call_chain(*args)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 503, in _call_chain
    result = func(*args)
  File "C:\Users\PC04\Anaconda3\lib\urllib\request.py", line 649, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 404: Not Found

I even tried restoring the repository to the latest working instance, and again it crashes with that excat same error.

I really don’t know what to do about it.

Thanks in advance!
