When trying this snippet  more than once I get a `ValueError: I/O operation on closed file.` exception. Any Idead why this might be the case?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,543197350

I think I understand this issue now. I am not an expert, but Xarray does not appear to be able to open netCDF from a url without a THREADS server. In this case 

```python
import xarray as xr
url = https://opendap.oceanobservatories.org/thredds/dodsC/ooi/dax.soule@qc.cuny.edu/20191228T052214778Z-RS03ECAL-MJ03E-06-BOTPTA302-streamed-botpt_nano_sample/deployment0001_RS03ECAL-MJ03E-06-BOTPTA302-streamed-botpt_nano_sample_20191005T000000-20191005T235959.950000.nc

ds = xr.open_dataset(url)
```
Works just fine. So I see how to make xarray work using OpenDAP, but I am still unable to open a file directly from object store using the HTTPS URL.

I am not sure that this is supported, but if it is I would love to see an example.
