@9xr Which page are you refering to? When you click it, a browser window will open with the url https://login.live.com/oauth20_authorize.srf?client_id=b35593c4-f505-47e4-9a45-4f0d24c3c007&response_type=code&redirect_uri=http://localhost:8089/auth&scope=XboxLive.signin, if you are unable to reach this then your DNS is blocking the domain (or possibly a browser plugin?), it's nothing we can control.
If thats the case and you are on Windows open network settings and change your DNS to 1.1.1.1 (CloudFlare) and it should work.
