Still receiving the same error using version 4.0.20.2.  See original
post below for the server links.


Here is a dataset where the Point subset is working correctly:
http://staging.asascience.com:8989/thredds/catalog/fmrc/GFS/catalog.html
?dataset=fmrc/GFS/GFS_best.ncd

And another which is not working correctly (same error):

download and try again? thanks
