DNS_PROBE_FINISHED_NXDOMAIN Error

I tried adding a subdomain and to verify my domain through google search console.

After I did, the site shows DNS_PROBE_FINISHED_NXDOMAIN error.

I deleted the subdomain records as well the google verification ones but it is still not working.

The domain is zetamedicine.com

Can someone please help?
