I use netlify to serve a community site mobretreat.org . I own the domain registered at external registar. I configured your DNS servers to be used with this domain.
On page https://app.netlify.com/sites/mobretreat/settings/domain#https I am shown a message
mobretreat.org doesn’t appear to be served by Netlify
We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our troubleshooting guide for more information on how to fix the problem, and then renew the certificate.
However the site is properly served and resolved using netlify name server
curl -s -v http://mobretreat.org 2>&1 | grep Server
< Server: Netlify
Additionally if I go to Netlify DNS I see three system records, one of them for domain test.mobretreat.org shouldn’t be there
How can I fix it?
