Is GMT server down?

I’m trying download a grid from GMT server but I always get an error message:

grdinfo [NOTICE]: -> Download cache file: @Terceira.nc
grdinfo [ERROR]: Libcurl Error: HTTP response code said error
grdinfo [WARNING]: You can turn remote file download off by setting GMT_AUTO_DOWNLOAD off.
grdinfo [ERROR]: File XX/XX/XX/XX.nc was not found
grdinfo [ERROR]: Cannot find file /XX/XX/.XX/XX/Terceira.nc
grdinfo [ERROR]: File /XX/XX/.XX/XX/Terceira.nc was not found
grdinfo [ERROR]: Cannot find file /XX/XX/.XX/XX/Terceira.nc
grdinfo [ERROR]: File File /XX/XX/.XX/XX/Terceira.nc was not found
[Session gmt (0)]: Error returned from GMT API: GMT_FILE_NOT_FOUND (16)

(I replaced folder paths by XX/)

There is no such grid in the GMT server.

Index of /cache/ (generic-mapping-tools.org)

The problem was in my script. I detected and fixed.
