First of all, please don’t post your own question in someone else’s topic just because the title describes your issue. Only reply to the topic if you are 100% sure you have the exact same issue. When in doubt, post a new topic instead.
As for your issue, if you see a directory listing, that means your DNS settings are fine. If you see a directory listing, that means your domain name is fully set up, and you should upload your website files.
That said, your domain name is working fine from here. Do you still see a directory listing?
