When making the below geoserver WCS request it seems that the BoundingBox param is ignored: &BoundingBox=-86,20,-76,40,urn:ogc:def:crs:EPSG::4269
Is my request written wrong or is BoundingBox not supported with WCS (I do see mention of it in the getcapabilities)? For WMS &bbox=-86,20,-76,40
works.
Here's the full WCS request but it's returning everything in the full extent of the raster (not just the part in the bounding box):

I recommend to read the WCS 2.0.1 standard https://portal.opengeospatial.org/files/09-110r4.
First thing that you must do is to check the metadata of the coverage with DescribeCoverare. A sample request:
http://demo.geo-solutions.it/geoserver/wcs?service=WCS&version=2.0.1&request=describecoverage&coverageid=nurc__Img_Sample
Read the response and find out the names of the axis, in this case
So the axis are "Lat" and "Long". Use them in the subset parameters of the GetCoverage query. For example for an area between 20 and 30 degrees N and between 100 and 90 degrees W use
The whole request (with URL-encoding) would be like
http://demo.geo-solutions.it/geoserver/wcs?service=WCS&version=2.0.1&request=getcoverage&coverageid=nurc__Img_Sample&subset=Lat(%2220%22,%2230%22)&subset=Long(%22-100%22,%22-90%22)
Your request should work if you rewrite it into
https://geoserver-dev.usanpn.org/geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&coverageId=si-x:average_leaf_best&subset=Lat(%2220%22,%2240%22)&subset=Long(%22-86%22,%22-76%22)&SUBSET=time(%222003-01-01T00:00:00.000Z%22)&format=geotiff
I am still not sure if the server at usanpn.org honors the Lat and Long subsets even it does accept the request.
