Projection problem from gdal2tiles.py to R Leaflet

I do have a projection problem when making tiles with GDAL command and using the same for Leaflet in R. The steps I am following are:

  1. In Centos Amazon Linux 2 and GDAL I Run the following command:

    gdal2tiles.py --s_srs EPSG:3857-WGS84 usa_tif.tif tiles

  2. After generating the tiles I get an openlayer.html which looks ok:

  1. But when I add the file into Leafet in R I get the following: enter image description here

Maybe you have an idea what is happening?

GDAL 3.2.1, released 2020/12/29
