PDF Embed API - File Preview Not Available

Greetings! 

I am having trouble getting the PDF embed API to work on my site. I keep encountering the message "File Preview Not Available" with any PDF file I try. The domain is a test site I created with Weebly https://corporatesampleintranetpage.weebly.com/.

The code I am using is: 

<div id="adobe-dc-view"></div>
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function(){
var adobeDCView = new AdobeDC.View({clientId: "<98a6ee14c3d64f3a8eae67ddf3534fc1>", divId: "adobe-dc-view"});
adobeDCView.previewFile({
content:{location: {url: "https://documentcloud.adobe.com/link/documents/files/sample.pdf"}},
metaData:{fileName: "ACORD.pdf"}
}, {});
});
</script>

Any and all help is VERY MUCH APPRECIATED!
