Hello.
Please tell me how to overcome the error when trying to use openapi VKontakte.

Access to XMLHttpRequest at ' https://login.vk.com/?act=openapi&oauth=1&aid=6995... ' from origin 'null' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values ' http://localhost, *', but only one is allowed.

Code to run (I just open the html page):

<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="https://vk.com/js/api/openapi.js?160" type="text/javascript"></script>
</head>
<body>
    <script type="text/javascript">

        window.onload = (function() {
            VK.init({
                apiId: 6995083
            });

            function authInfo(response) {
                console.log(response);
            }
            
            VK.Auth.getLoginStatus(authInfo);
        })
    </script>
</body>
</html>

Another. No localhost address !!! It does not exist in nature! localhost or 127.0.0.1 points to the same computer from which it is called!!! VK your ip is unknown!!!
