gaierror

[swyuhui]

I have been using fredapi to download data from FRED API without problem. But I've been trying to run the same codes that I had before in these two days and I keep getting something called "gaierror".

Here is the codes that I ran (I just masked the API key):
from fredapi import Fred
fred = Fred(api_key='xxxxxxxxxxxxxxxxxxxxxxxxx')
import pandas as pd
data = fred.get_series('SP500')

and I got the following error. Can anyone help me to understand what error it is and how to solve it? Thanks a lot.
