Has there been a change at yahoo regarding cookies?

KeyError                                  Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/yahoofinance/historicaldata.py in _find_cookie_crumb_pair(self, locale)
     71         #try:

     73         #except KeyError:

4 frames
KeyError: "name='B', domain=None, path=None"

During handling of the above exception, another exception occurred:

ValueError                                Traceback (most recent call last)

Anyone else experienced this issue?

I got the very same issue since yesterday. Before that, it was working just like a charm.

@0a1b since I don't want to spend time in debugging this I have tried to find an alternative to this library and I have found panda data reader.
Now, I don't know what you are using this library for but i am using it for retrieveing historical data for crypto currencies.
A quick exampe

importpandas_datareader as web
cryptoHistory = web.DataReader(symbol, 'yahoo', inceptionDate, today)

cryptoHistory will be a panda dataframe as per the call of the API from yahoofinance. To me it was not much of an effort to switch between the two.
I hope this can help you.
