Unable to download VIIRS images with GIBS API and gdal_translate

I’m trying to download some VIIRS images from GIBS API. I’m using gdal:

gdal_translate -projwin 19.07 42.16 28.39 34.5 -of "GTiff" "viirs.xml" "VIIRS_SNPP_DayNightBand_ENCC.tif"

The viirs.xml file contains:

<GDAL_WMS>
    <Service name="TMS"><ServerUrl>https://gibs.earthdata.nasa.gov/wmts/epsg4326/best/VIIRS_SNPP_DayNightBand_ENCC/default/2017-08-21/500m/${z}/${y}/${x}.png</ServerUrl>
    </Service>
    <DataWindow>
        <UpperLeftX>-180.0</UpperLeftX>
        <UpperLeftY>90</UpperLeftY>
        <LowerRightX>396.0</LowerRightX>
        <LowerRightY>-198</LowerRightY>
        <TileLevel>7</TileLevel>
        <TileCountX>2</TileCountX>
        <TileCountY>1</TileCountY>
        <YOrigin>top</YOrigin>
    </DataWindow>
    <Projection>EPSG:4326</Projection>
    <BlockSizeX>512</BlockSizeX>
    <BlockSizeY>512</BlockSizeY>
    <BandsCount>4</BandsCount>
</GDAL_WMS>

But, it returns the following error:

Input file size is 131072, 655360
ERROR 1: GDALWMS: Incorrect bands count 1 in downloaded block, expected 4.
