Correctly convert leaflet bounding coordinates to rasterio bounding coordinates

I have a raster (geotiff) I am trying to clip to the bounding box of the visible leaflet map on my webpage. To get the visible bounding box I am using map.getBounds(); in javascript then passing it over to python. I am then attempting to clip my raster in rasterio using rasterio.windows.from_bounds

However the coordinates from leaflet dont return the correct area of the raster. Anyone know why this is and how I can get the correct coordinates?

GDALinfo on the original raster shows the following:
