Add   <TileMatrix>19</TileMatrix>

It appears that there are not tiles at zoom level 20, at least in this area.

If you add --debug on to the gdal_translate, you'll see:

The reason the error is silent is because of the
<ZeroBlockHttpCodes>204,404</ZeroBlockHttpCodes>

If you remove that, then gdal_translate would have failed.
