I am creating some netCDF files with more than 1 band using GDAL (2.4.1).

The created files (an example file in attachment) works fine in QGIS 2.18 (and other GIS apps), but I get the following errors with QGIS 3+ (ltr, dev, etc.) on OSGEO4W64:

2019-04-07T16:16:16     CRITICAL    Invalid Layer : Raster layer Provider is not valid (provider: gdal, URI: C:/gdal.nc
2019-04-07T16:16:16     CRITICAL    Invalid Data Source : C:/gdal.nc is not a valid or recognized data source.

If I create a netCDF file with just 1 band (example attached), QGIS 3+ reads the file smoothly.

This issue may be related to #28740, #28799 and #29464
