Checking Chrome's console, the following error message 416 Range Not Satisfiable related to a GeoTIFF (hillshade) is shown, where it has overviews and it is displayed as explained in this OpenLayers example. Even though this GeoTIFF displays well in GIS software such as QGIS, it does not appear in OpenLayers, here the console output:

Any hints are welcomed,
