Problem with custom domain website not working

Hello, I have serious problem. I’ve deployed a website by the name mtb06.netlify.app and it works fine. But when I’ve changed the domain name to custom domain mountainbike06.com it worked at first but now it stopped working and it’s giving me the error: This site can’t be reached

Check if there is a typo in www.mountainbike06.com.

Plase, I would appreciate any help !

Hi there @ValdrinMurtezi! Are you looking to use Netlify DNS or external DNS? I’m not seeing any NS records configured with your domain. You’ll want to set up DNS following this support guide:
