adobe blocked by CORS policy but URL is in allowed domain for API settings?

[Joseph24206727ky4h]

Im having some issues with the embed API. the PDF pops up and then instantly disappears when I check dev tools I see the below error.

Access to fetch at 'https://viewlicense.adobe.io/viewsdklicense/jwt' from origin 'https://download.militaryonesource.mil' has been blocked by CORS policy: No 'Access-Control-Allow-Origin'.

But I'm not sure why i am getting this error as the allowed domain is set to allow this URL  (download.militaryonesource.mil) in the API config.

<div id="adobe-dc-view" style="width: 800px;">

</div>

<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>

<script type="text/javascript">

const queryString = window.location.search;

const params = new URLSearchParams(document.location.search);

document.addEventListener("adobe_dc_view_sdk.ready", function() {

var adobeDCView = new AdobeDC.View({

clientId: "SOMECLIENTID",

divId: "adobe-dc-view"

});

adobeDCView.previewFile({

content: {

location: {

url: "https://download.militaryonesource.mil/12038/MOS/ResourceGuides/The_Days_Ahead_Spanish.pdf"

}

},

metaData: {

fileName: "SPA.pdf"

}

}, {

embedMode: "IN_LINE"

});

});

</script>
