How can I troubleshoot Discourse comments embedding feature?

@purldator here are my embed settings (sorry, I can’t embed images or link to them):

  • embeddable hosts: ddhstaging.satapps.org
  • feed polling enabled: {unchecked}
  • feed polling url: {blank}
  • embed by username: ddhdatasets
  • embed username key from feed: {blank}
  • embed category: Data Discovery Hub Datasets
  • embed post limit: 100
  • embed truncate: {unchecked}
  • embed whitelist selector: {blank}
  • embed blacklist selector: {blank}

My site is a data catalog based on CKAN , pages are generated from templates. Here’s what the Discourse snippet looks like on this page:

  <div id="discourse-comments"></div>

<script type="text/javascript">
  var discourseUrl = 'http://forumstaging.satapps.org/',
      discourseEmbedUrl = 'http://ddhstaging.satapps.org/dataset/473cdee9-565c-4a9b-99a8-e8c836837086';

  (function() {
    var d = document.createElement('script'); d.type = 'text/javascript'; d.async = true;
      d.src = discourseUrl + 'javascripts/embed.js';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(d);
  })();
</script>

Any pointers will be greatly appreciated.
