Cannot access ECCOv4 data from PODAAC via OPeNDAP

[mikejmnez]

Hi,
I am trying to access ECCOv4 model output via OPeNDAP. I have been able to in the past. But the data seems unavailable lately. I can discover the urls via CMR or Earthdata Search, but keep getting 500 errors with the message:
"DMR++ parse error: No document element found "

Here is a URL I got from Earthdata Search:

https://opendap.earthdata.nasa.gov/providers/POCLOUD/collections/ECCO%20Ocean%20Temperature%20and%20Salinity%20-%20Monthly%20Mean%20llc90%20Grid%20(Version%204%20Release%204)/granules/OCEAN_TEMPERATURE_SALINITY_mon_mean_2017-12_ECCO_V4r4_native_llc0090

normally adding .dmr works to retrieve the metadata but even that seems unavailable...

Thanks!
