Have a look at https://gis.stackexchange.com/questions/395867/opening-a-grib-from-the-web-with-gdal-in-python-using-vsicurl-throws-error-on-m. There gdalinfo fails with /vsicurl/ somewhere in the middle of the grib2 file when the server sends http 302 as a response for a range request. The file is OK as was tested by downloading it first totally with curl. Could it be that the http "moved permanently" at that stage makes /vsicurl/ to fail?

I made also a few tests and it seems that the error may happen in another http range, but it is always similar:
VSICURL: Got response_code=302
GRIB: ERROR: Ran out of file in Section 7
