What I’m seeing is: It gets redirected to http://sonicswifty.ml/?z and says ‘This will only take a moment. Please wait…’ For some reason, the only browser which doesn’t do this (Chrome, Firefox, Edge Chromium Beta, IE) is the old Microsoft Edge.
You can also add a domain name to an account which already exist (and was created using another domain name or a free subdomain).
You can add the domain name as a Alias Domain (Parked Domain) or Addon Domain. The Alias Domain section allows you to attach the domain name to an existing website, the Addon Domain section allows you to create a new website for the domain (or upload an existing website). For both domain types, the process is the same.
To add the domain, you need to find the Addon Domain or Alias Domain section in your control panel, enter your own domain name in the field and click Add Domain.
It looks like the nameservers are returning a Bodis DNS record for your domain, which it shouldn’t.
Can you please try to remove the domain from this account and then add it again? That might cause the correct DNS records to be sent through the system and applied to your domain.
