Currently congral.tech appears to use Namecheap DNS, and there are no A records. There is a CNAME on the www subdomain pointing to congral-tech.digitalpress.blog.
Have you added congral.tech to Netlify under the Domains area of the UI?
Read the above support guide and configure congral.tech as per the appropriate documentation linked above. I use Namecheap myself so if you have any further issues, I’m happy to help.
Further support guides for DNS/SSL are also compiled in
