404 Error getting JSON from Instagram Graph

I am developing an application for a client which uses the Instagram graph to search for a specific hashtag. For this I use the following JavaScript:

let rawData, resuData;
$.ajax({
url: 'https://www.instagram.com/explore/tags/dogs/?__a=1',
type: "GET",
dataType: "json",
success: function(data) {
    //console.log(data);
},
complete: function(data_response) {
    rawData = (data_response.responseText);
    resuData = JSON.parse(rawData);
    console.log(resuData);
},
error: function (error) {
console.log("Error!");
}
});    

This gives me a JSON with the data I want.

The problem comes when I want to obtain the data from the "elbaresotracosa" hashtag (https://www.instagram.com/explore/tags/elbaresotracosa/?__a=1) which shows me the message error 404 as shown in the following image.

error 404 instagram graph

But when I enter that URL from the browser itself, it shows me the JSON that I'm looking for.

instagram graph JSON

In the developer tools, from the Network tab, it says that the content-type is "application/json"

content-type: application/json

Do any of you have any idea how I can solve this problem?
