I’m directed to an advertisement page going to your site. Same issue for me getting to your site.

Yes, it looks like the DNS records for your domain in our nameservers is incorrect. Can you please try to remove and re-add this domain to your account? You can do that through the Addon Domains or Parked Domains section in the control panel.
