ui.encyc.article_urls_titles() cannot get a response from encycfront. It gets a 403 from encycfront:

>>> from django.conf import settings
>>> import requests
>>> from ui import encyc
>>> url = '%s/api/0.1/articles/' % settings.ENCYC_BASE
>>> url
'https://encyclopedia.densho.org/api/0.1/articles/'
>>> r = requests.get(url, timeout=10)
>>> r.status_code,r.reason
(403, 'Forbidden')

elinks on the same server returns the API call just fine:

elinks https://encyclopedia.densho.org/api/0.1/articles/
