IERSRangeError after downloading table from USNO

See original GitHub issue

Description

Recent dates don’t seem to be included in the IERS table when I force a fresh download

Expected behavior

I expected to convert a recent date

Actual behavior

astropy.utils.iers.iers.IERSRangeError: (some) times are outside of range covered by IERS table.

Steps to Reproduce

# Put your Python code snippet here.
from astropy.utils.data import download_file
from astropy.time import Time, TimeDelta
from astropy.utils import iers
url = 'https://maia.usno.navy.mil/ser7/finals2000A.all'
filename = download_file(url, cache=False)  # Force download of latest copy
dat = iers.IERS_Auto.read(file=filename)
iers.IERS.iers_table = dat
iers.conf.auto_download = False
(Time.now()-TimeDelta(3)).ut1 #Raises Error
# astropy.utils.iers.iers.IERSRangeError: (some) times are outside of range covered by IERS table.
for i in range(1000):
    try:
        LastDate = (Time('2021-01-11')+TimeDelta(i)).ut1
    except iers.iers.IERSRangeError:
        print(Time('2021-01-11')+TimeDelta(i))
        break
# 2022-02-06 00:00:00.000 is the first date that cannot be converted

Setting earth_orientation_table explicitly works for me. Thank you!
