KML图层不显示在地图上

我正试图在Google地图上显示KML。地图加载完美，但KML完全不显示。另外，我在控制台中没有收到任何错误消息。KML图层不显示在地图上

我从gadm.org下载了一个.kmz文件，解压缩并提取.kml文件。

这是我的代码和我的KML的URL。 http://locallocal.com/endline/mex2.kml

<script> 
    var map; 
    var src = 'http://locallocal.com/endline/mex2.kml'; 

    /** 
    * Initializes the map and calls the function that loads the KML layer. 
    */ 
    function initMap() { 
    map = new google.maps.Map(document.getElementById('map'), { 
     center: new google.maps.LatLng(-19.257753, 146.823688), 
     zoom: 2, 
     mapTypeId: 'roadmap' 
    }); 
    loadKmlLayer(src, map); 
    } 

    /** 
    * Adds a KMLLayer based on the URL passed. Clicking on a marker 
    * results in the balloon content being loaded into the right-hand div. 
    * @param {string} src A URL for a KML file. 
    */ 
    function loadKmlLayer(src, map) { 
    var kmlLayer = new google.maps.KmlLayer(src, { 
     suppressInfoWindows: true, 
     preserveViewport: false, 
     map: map 
    }); 
    google.maps.event.addListener(kmlLayer, 'click', function(event) { 
     var content = event.featureData.infoWindowHtml; 
     var testimonial = document.getElementById('capture'); 
     testimonial.innerHTML = content; 
    }); 
    } 
</script> 
<script async defer 
src="https://maps.googleapis.com/maps/api/js?key=[MYKEY]&callback=initMap">
