That domain name has expired on 2024-11-22, and your domain registrar has changed the name servers to become:
ns1.renewyourname.net
ns2.renewyourname.net
It looks like you haven’t paid your yearly renewal fees to your domain registrar, apparently “SG Hosting Inc.” (SiteGround).
Contact your domain registrar, and ask them for assistance in how you can recover your domain name (such as e.g. by paying renewal fees, paying redemption fees, et al).
