Description
This WCS:
http://thredds.ucar.edu/thredds/wcs/grib/NCEP/WW3/Regional_US_West_Coast/Best
It doesn't seem to be possible to add the layers. I get:
2019-01-20T12:03:18 CRITICAL Invalid Layer : WCS provider Cannot get test dataset.
Raster layer Provider is not valid (provider: wcs, URI: cache=PreferNetwork&crs&dpiMode=7&format=GeoTIFF_Float&identifier=Wind_speed_surface&time=2018-12-21T00:00:00Z&url=http://thredds.ucar.edu/thredds/wcs/grib/NCEP/WW3/Regional_US_West_Coast/Best
For some reason, QGIS is making the request with these CRS/RESPONSE_CRS parameters (obviously that's an invalid CRS):
CRS EPSG:0 [Latitude_Longitude]
RESPONSE_CRS EPSG:0 [Latitude_Longitude]

Ok, if you think it's a duplicate, but they're both using the same error to report two different bugs in QGIS.
One is that QGIS cannot connect to the WCS, the other is that QGIS doesn't handle WCS exception reports properly.

Invalid request constructed because QGIS WCS provider handles only requestResponseCRSs element of the DescribeCoverage response. When this element is not found, it tries to get CRS from the RectifiedGrid element.
WCS server mentioned in the ticket reports invalid(?) CRS in that element
<gml:RectifiedGrid srsName="EPSG:0 [Latitude_Longitude]" dimension="2">
Here is an attempt to fix CRS handling https://github.com/qgis/QGIS/pull/9005
