I was able to use the temporary solution to get the data I needed from IRI at the moment. The example still generates error while I tried and have some similar error when downloading the NMME hindcasts.

It never did, but that used to be ok because older versions of netcdf-c didn't encode the querystrings. More recent versions do. So a change in netcdf-c is the proximal cause of the example breaking, but the root of the problem is on the server side.
We (IRI) are working on fixing the server software.","{""total_count"": 4, ""+1"": 4, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,811409317

This works for me on mac0S: `conda create -c conda-forge -n opendap_working python xarray netcdf4==1.5.1 matplotlib` Note that I found the explicit pin important. Perhaps because it brings in libnetcdf=4.6.2 behind the scenes? Here is my full list of working versions:

Hopefully some folks that know more about opendap could chime in (@dopplershift, @rabernat ?) to help get to the root of this issue. For what it's worth, I noticed this additional log output that wasn't surfaced in the jupyter notebook in addition to the original traceback i posted:

But this error persists when pinning netCDF4 to version 1.5.1..
Got to the issue because I got the same error when trying to clip another IRI dataset with OpenDAP.
