Description

I get an error (TypeError: cannot unpack non-iterable NotImplementedType object) pulling GOES/XRS data from SunPy on Windows using the code below. This works with no issues on MacOS.

TypeError: cannot unpack non-iterable NotImplementedType object

Expected vs Actual behavior

The files download on MacOS and can be analyzed without issue.

Steps to Reproduce

from sunpy.time import parse_time
from sunpy import timeseries
from sunpy.net import Fido, attrs as a

result = Fido.search(
    a.Time('2013/11/04 06:00', '2013/11/06 00:00'),
    a.Instrument.xrs,
) 
files = Fido.fetch(result)

goes = timeseries.TimeSeries(files, concatenate=True, ) 
goes = goes.truncate('2013-11-05 22:00','2013-11-05 23:00')
