Sorry for the late reply. Can you try adding `discourseReferrerPolicy: 'no-referrer-when-downgrade'` to the `DiscourseEmbed` object that’s set in the embed code snippet? There is a full example of a code snippet that adds that property here: [Embed Discourse comments on another website via Javascript - #353](https://meta.discourse.org/t/embedding-discourse-comments-via-javascript/31963/353).

If you try that, please let us know if it solves the issue for you.

I think this was resolved here: [Embed Discourse comments on another website via Javascript - #365](https://meta.discourse.org/t/embedding-discourse-comments-via-javascript/31963/365). In that case the problem was a missing `www` subdomain on the Discourse embeddable host record.

Edit: this issue has now been fixed in the core Discourse code. There is no longer a need to set the `discourseReferrerPolicy` variable to `'no-referrer-when-downgrade'`. Discourse now sets the referrer policy to `'no-referrer-when-downgrade'` by default. For details about this, see [https://meta.discourse.org/t/embedding-discourse-comments-via-javascript/31963#setting-the-referrer-policy](https://meta.discourse.org/t/embedding-discourse-comments-via-javascript/31963#setting-the-referrer-policy).
