[gradsusr] SDFOpen Failure

Hi,
I'm having an issue with the sdfopen command on the production dods server.

Using the following command:
sdfopen https://nomads.ncep.noaa.gov/dods/nam/nam20210426/nam_12z

I receive the following error message:

Scanning self-describing file: https://nomads.ncep.noaa.gov/dods/nam/nam20210426/nam_12z
curl error details:
Error: nc_open failed to open file https://nomads.ncep.noaa.gov/dods/nam/nam20210426/nam_12z
NetCDF: I/O failure
gadsdf: Couldn't ingest SDF metadata.

And starting 4/20 with the 12Z run of the model, many of my batch jobs to retrieve data using the above approach no longer work. But it's funny, some still do work. Its a real head scratcher.

Anybody have any insight as to what's going on?

Thanks,
Mark
