See below, for details, but as far as I can tell it looks like: * my conda env (""EQ"") has the same curl, libcurl, ca-certificates, and certifi as your system. * the ncdump commands gives same error (as netcdf4 and xarray). I should post an issue at netcdf4, correct? ``` (EQ) PS C:\Users\Codiga_D> conda list curl # packages in environment at C:\Users\Codiga_D\AppData\Local\Continuum\miniconda3\envs\EQ: # # Name Version Build Channel curl 7.83.1 h789b8ee_0 conda-forge libcurl 7.83.1 h789b8ee_0 conda-forge (EQ) PS C:\Users\Codiga_D> conda list certifi # packages in environment at C:\Users\Codiga_D\AppData\Local\Continuum\miniconda3\envs\EQ: # # Name Version Build Channel ca-certificates 2022.6.15 h5b45459_0 conda-forge certifi 2022.6.15 py37h03978a9_0 conda-forge (EQ) PS C:\Users\Codiga_D> ncdump -h http://psl.noaa.gov/thredds/dodsC/Datasets/NARR/monolevel/uwnd.10m.2000.nc Error:curl error: SSL connect error curl error details: Warning:oc_open: Could not read url C:\Users\Codiga_D\AppData\Local\Continuum\miniconda3\envs\EQ\Library\bin\ncdump.exe: http://psl.noaa.gov/thredds/dodsC/Datasets/NARR/monolevel/uwnd.10m.2000.nc: NetCDF: I/O failure ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1299316581 https://github.com/pydata/xarray/issues/6766#issuecomment-1179305426,https://api.github.com/repos/pydata/xarray/issues/6766,1179305426,IC_kwDOAMm_X85GSsXS,10137,2022-07-08T19:36:39Z,2022-07-08T19:36:39Z,NONE,"Thanks for the quick response. Result from `xr.show_versions() `is below. I tried `netCDF4.Dataset(url) `and it gave the same error. Just a thought: I still wonder if this could be related to certification... which is something that did change on my system recently. I looked for information as to where netCDF4 would check for its certificate chain, but wasn't able to find something useful so far.
