How can I solve "Access to XMLHttpRequest at URL from origin URL has been blocked by CORS "

Hi,
I am facing this issue:
Access to XMLHttpRequest at ‘https://skaleblog.ghost.io/blog/tag/technology/page/2/’ from origin ‘https://skale.network’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

I created a load more post button. It is working on localhost but not working on server. I am using Ghost Pro. Here main domain is https://skaleblog.ghost.io/blog/ and site is working on https://skale.network/blog

I tried to solve these issues using https://stackoverflow.com/a/47525511/4521776
But nothing changes.

My code:

var pagination_next_page_number = '{{ pagination.next }}',
    pagination_available_pages_number = '{{ pagination.pages }}';

///// Load more posts JS
var nextPage = $('link[rel=next]').attr('href'),
    a = $('.load-more'),
    b = $('.loadmore-section')
if (!nextPage) {
    b.addClass('d-none')
}
a.click(function (n) {
    n.preventDefault()
    var i =
        nextPage.split(/page/)[0] +
        'page/' +
        pagination_next_page_number +
        '/'
    $.ajax({
        url: i,
        crossDomain: true,
        headers: {  'Access-Control-Allow-Origin': 'https://skale.network/blog/' },
        beforeSend: function () {
            a.html(
                '<svg version="1.1" id="loader-1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="30px" height="30px" viewBox="0 0 40 40" enable-background="new 0 0 40 40" xml:space="preserve"><path opacity="0.2" fill="#fff" d="M20.201,5.169c-8.254,0-14.946,6.692-14.946,14.946c0,8.255,6.692,14.946,14.946,14.946s14.946-6.691,14.946-14.946C35.146,11.861,28.455,5.169,20.201,5.169z M20.201,31.749c-6.425,0-11.634-5.208-11.634-11.634c0-6.425,5.209-11.634,11.634-11.634c6.425,0,11.633,5.209,11.633,11.634C31.834,26.541,26.626,31.749,20.201,31.749z" /><path fill="#fff" d="M26.013,10.047l1.654-2.866c-2.198-1.272-4.743-2.012-7.466-2.012h0v3.312h0C22.32,8.481,24.301,9.057,26.013,10.047z"><animateTransform attributeType="xml" attributeName="transform" type="rotate" from="0 20 20" to="360 20 20" dur="0.5s" repeatCount="indefinite" /></path></svg>'
