[THREDDS #LKU-725505]: works on localhost, but when I use our production server, I get Connection refused



Hi Rich,

It looks like the connection to the URL is being refused. Not the HTTP request 
failing but the opening of the connection. Can you access the OPeNDAP URL (plus 
".dds" or something) listed in the error message from your server machine:

http://ourocean.jpl.nasa.gov:8080/thredds/dodsC/las/SCBfcst/scb_latest_fcst_roms.nc.dds

Or any other URL on that server?

My first thought was network issues between your server and the JPL server that 
aren't affecting your laptop. If it isn't a network issue, the only other thing 
that comes to mind is if someone running the JPL server saw lots of hits from 
your machine and set Tomcat to refuse connections with your server. Or they 
have something automated to block heavy traffic.
