Does this dataframe look correct?

[Jim]

linux mint 19.3, python 3.6

I wrote a program to download stock info from yahoo using yfinance. I 
have been running it unchanged for the past 3 months, today it gave an 
error. When looping through a list of stocks the error is random, never 
the same position in the list.

I wrote the following little test script to show the error:

import yfinance as yf
import pandas as pd
day = '2020-06-25'
aapl = yf.Ticker('AAPL')
hist = aapl.history(start=day)
print(hist)
close = hist.loc[day]['Close']

I ran it 10 times 8 times I got a dataframe and 2 times I got the error 
shown below:

I don't know pandas that well. My only contact with it is when a module 
I am using depends on it. So does the dataframe look correct?

The error complains of line 1, column 1. Just looking at the dataframe 
it looks like Date is on a different line from the rest of the headers 
or is that just the result of being printed in the terminal?

On the yfinance github issues page there were a few people reporting 
this error. A couple of people reported a work around using try/except. 
It worked for some people and not others. It didn't work for me.

I'd appreciate any advice you could give.

Thanks,  Jim
