Experiencing DNS_PROBE_FINISHED_NXDOMAIN [Please help]

Hi Webflow community,
I’m not a very techy person that’s why I’m having a hard time in dealing DNS_PROBE_FINISHED_NXDOMAIN error to my published domain.

My domain is jeremyfabia.com

Here is my Publishing settings:

Hopefully someone can help me. Thanks

Edit: I don’t have a dns provider yet. Should I need to get one?

Registering domain secures it for your use. In order for records to be resolved (found) the zone must be hosted on a public dns server where you can set the zone records as needed. Review the docs in the university.
