The whole map is not showing in the browser

I create a series of layers in QGIS and use Qgis2threejs to create a 3D model I do File>Export to Web which seems to work (no error messages) It works in my local environment but when I export it to any of my hosts, it fails to load At best I see the "sky" and the controls and sometimes parts of the scene

Does every layer have the same EPSG? If not, reproject every layer to the same an try again.
