I Can't Connect to My Newly Created Website!!

Hello everyone. I purchased hosting from Hostinger and got my domain from Natro. I configured the settings and the site was opening fine. Later, I clicked to update the website via WordPress. Since then, it only accessed the site once, but never again. When I type the URL, Natro's warning "This Domain Name is Registered and is Using Natro Park Page" appears. Is this related to the site being new? Is it a normal situation or abnormal? I appreciate any help. Thank you in advance to everyone who responds.
