I've been using yfinance for a while. When I went on holiday downloading data with yfinance and pandas_datareader stopped working for me. I guessed it was caused by something to do with a different connection. When I arrived back from holiday I still had issues with my code that I've used before without issues. I don't understand the error message and would appreciate if anybody could help resolve the issue.
This is some basic code:
import pandas as pd
import yfinance as yf
import datetime as dt
start = dt.date(2020,1,1)
end = dt.date(2021,1,1)
ticker = 'AAPL'
df = yf.download(ticker,start,end)
print(df)
This code has worked for me in the past however I now receive the following error message:
Exception in thread Thread-1:
