Question

OAuth

I want to implement authorization through OAuth, I do everything as it is written, I get code , I go to the site, I make a request for a token https://github.com/login/oauth/access_token , it gives an error that the request to sources is blocked
, here is the request for a token

return await Vue.axios({
      url: "https://github.com/login/oauth/access_token",
      method: "POST",
      params: {
        client_id: clientId,
        client_secret: clientSecret,
        code
      }
    });
