[python #JBO-988533]: Access to NCSS in THREDDS

Greetings Greg!

You're not doing anything wrong, but you have found a bug :-)
thredds-jumbo is actually pointing to thredds-test, which is our
public facing test thredds server. The bug has been fix at this point,
and I plan on updating the TDS with the issue later today (just waiting
on one pull request to go through).

That said, the fix is running on thredds-dev, so if you just use url2 for
now, then you should be good to go - let me know if not.

Cheers!

Sean
