I can see in the log **Job exception: 404 Not Found**

And backtrace log :

And this is the code used to embed :

```javascript
    <div id='discourse-comments'></div>

    <script type="text/javascript">
      DiscourseEmbed = { discourseUrl: 'https://forum.teambac.fr/',
                         discourseEmbedUrl: window.location };

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

```
