LetsEncripyt fails to create a certificate for a subdomain in a LoadBalance

A subdomain was created pointing correctly to a LoadBalancer working perfectly with a droplet, on port 80.

But when trying to configure for https and obtain a LetsEncrypt certificate, “NO SENSE” failure occurs.

Failed to validate nameserver records: one or more DigitalOcean Name Server not found for domain.

It seems to me, searching the web, that this type of problem has already occurred in the past.

I opened a ticket but so far with no answer.


I have the same issue, looking forward to it.

Check your DNS registers in DigitalOcean, three DNS records must be missing:

NS 1800 NS 1800 NS 1800

I add this and resolve this issue.
