Load HTML file from remote

I hosted my html content in cloud. Then trying to load the html content in the editor I found the error:  "**Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.**"

My code: const editor = () => grapesjs.init({
    container: '#editor-portal',
    canvas: {
        styles: ['https://codepen.io/mrajeshkrossark/pen/mGLyJX.css']
    },
    plugins: ['gjs-preset-webpage'],
    pluginsOpts: {
		"gjs-components":[]
	},
    storageManager: {
        type: 'remote',
        storeHtml: true,
        storeCss: true,
        urlStore: "http://www.lightblue.byethost4.com",
        urlLoad: "http://www.lightblue.byethost4.com",
        params: {},
    }
});

Note: I wrapped the grapesjs editor into react application.
