site page says comming soon

The domain is currently pointing at 1 and 1, not Hostgator. At least, that is what I see on my web browser.

Best to talk to Hostgator Support or read some of their info on changing Name Servers.

As already mentioned, most likely a dns problem. Is 1&1 your domain registrar? Check out the following page about changing Name Server directly from hostgator. https://support.hostgator.com/articles/hosting-guide/lets-get-started/dns-name-servers/how-to-update-your-nameservers-with-1-1

Hope this helps!
