Actually, you installed the wordpress and created a website on a temporary link. Without adding a nameserver (or A record), how can you add a website on any hosting?
If a user adds a domain to Hostverge without setting a nameserver and then installs WordPress on that domain, it will install on a temporary link, which is why your website is displayed on a temporary link. If you wish to switch to the main domain, you must convert the temporary URL path to the original domain path in all files and databases. This is a difficult process that must be completed by a professional.
That is why we recommend uninstalling files and directories from that domain’s file management and then reinstalling WordPress. If you have important files, you can make a backup.
