short code – Instagram URL becomes oEmbed

I have 8 Instagram URLs in this post, of which 3 do not convert to embed / iframes.

I am using the Gutenberg insertion blog on Instagram to add the URL & # 39; s.https: //blog.wwf.sg/ocean/2018/11/netflix-documentaries-our-planet-okja-dogs/#

I see the block code in the classic editor that is the same as other instagram blocks that are processed correctly, but for https://www.instagram.com/p/BqDzw0CF3pC/ it simply returns the URL.


I tried to use shortcode, it is also the same result that only the 3 Instagram posts that appear below are not processed.

I need help to solve this problem.
