Instagram feed on my website is not refreshing

I'm using my Instagram feed on my website with the following endpoint:

https://api.instagram.com/v1/self/media/recent?access_token=ACCESS-TOKEN

That should bring all my posts, but it's not showing recent posts. The last one fetched is from September 17 and since then i made two new posts.

I'm really lost as what could be the problem. There is no other endpoint i can use and the access token is okey.

Im using PHP to retrieve the data, but even if I take a look at the raw JSON data, it's not getting the latests posts either.

Any clues anyone?

Thank you.
