Ajax request is not working with JSON feed url.

I am trying to fetch json feed using Ajax request but it’s not working. it always results in error, I tried using jsonp or json as dataType, also “application/json”, “text/plain”, as contentType but still resulting in error.
Json feed: https://blog.piscessportfishing.com/feed/json/

Ajax code:

$.ajax({
    type: 'GET',       
    url: "https://blog.piscessportfishing.com/feed/json/",
    dataType: 'json',
    data: {},
    success: function(data) {
        console.log(data);            
    },
    error: function (Request, textStatus, errorThrown) {
        alert("Request=" + Request.responseText + "\ntextStatus=" + textStatus + "\nerrorThrown=" + errorThrown);
    }        
  });
