Internal-network use of ██████████ no longer works #9058
Description
Issue JP-3838 was created on JIRA by David Law:
With thanks to Rachel Plesha for the original report, it looks like internal usage of CRDS from ██████████ no longer seems to be working.
Typically, most users need to set both CRDS_PATH and CRDS_SERVER_URL, so that necessary files will be pulled from the server and cached locally at CRDS_PATH. However, I believe there was also a method where users on the STScI internal network didn't need to do either of these, as the pipeline would default to using information on a shared disk at ██████████ (thereby saving internal users the need to download their own copies of all reference files).
It's been a long time since I last tried using this approach myself, but indeed it looks like it's now not working. Traceback in comments below, although it should be easy to reproduce for anyone by simply deleting the env variables.
Any thoughts Jonathan Eisenhamer? Also tagging Rosa Diaz Meaghan McDonald Hunter Brown
