Hello Manuel,

The URL you are using is a WMS GetCoverage request. The response to this 
request is a full netCDF file, without HTTP byte range support. The netCDF-java 
library doesn't support non-"byte range" HTTP access to remote netCDF files.

From the dataset page for this dataset

http://motherlode.ucar.edu:8080/thredds/catalog/galeon/testdata/catalog.html?dataset=galeon/testdata/striped.nc

there are two other services supported for this dataset: OPeNDAP and a straight 
HTTP service. The netCDF-Java library can open this dataset using either of 
those services (OPeNDAP, the first link below, should be preferred for 
performance reasons):

http://motherlode.ucar.edu:8080/thredds/dodsC/galeon/testdata/striped.nc
http://motherlode.ucar.edu:8080/thredds/fileServer/galeon/testdata/striped.nc

The dataset subsetting that was part of your WCS request (e.g., "coverage=ta" 
and "time=..." and "bbox=...") will have to be handled with the netCDF-java API 
(either in index space or using GridDataset).

Hope that helps,

Ethan
