web.DataReader + "fred": Failed Downloads

[dhruvsingh14]

Running this in jupyter notebook:

start = datetime.date.today() - datetime.timedelta(days=5 * 365)
end = datetime.date.today()
df = web.DataReader(["sp500", "NASDAQCOM", "CBBTCUSD"], "fred", start, end)

Gives me this error:

[100%%*] 3 of 3 completed

3 Failed downloads:
['CBBTCUSD', 'NASDAQCOM', 'SP500']: Exception('%ticker%: No timezone found, symbol may be delisted')

What can I do to fix it?
