Hi Oscar, > I don't know what is "-1".

I browsed all the way down to the dataset you had trouble with > > http://ers.cmima.csic.es:-1/thredds/dodsC/ers/2007/06-Jun/08/20070608.0951.n17.nc.bz2 but without a port number and could access it through OPeNDAP. Can you try it again and make sure there is no port number of "-1"? And let us know if it fails for you or if the "-1" pops back up.
