Unable to reissue the Let's Encrypt SSL certificate in Plesk: DNS problem SERVFAIL looking up TXT

    These appear to describe a previous version of Plesk. There is nothing in my Plesk panel that lets me go Domains>mydomain.com>Lets's Encrypt. When I do the next most logical thing (Websites & Domains>SSL/TLS Certificates>Install a free basic certificate provided by Let's Encrypt) and click Install, there is no DNS TXT record shown to me to add to my DNS. All I get is a choice of certificates, followed by the failure message,
    "Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/14789753017.
    Type: urn:ietf:params:acme:error:dns
    Status: 400
    Detail: DNS problem: SERVFAIL looking up A for [domain name]- the domain's nameservers may be malfunctioning"
    I troubleshoot: the nameservers at the registrar are set to ns1.vultr.com (and ns2 ditto), at vultr the DNS record is set to the correct IP for this domain, and when I go to whatsmydns.net and look for my domain name, I get the correct IP. And yet Letsencrypt is looking for something else. What?

    Let's encrypt is broken within Plesk. Unable to verify A records, when each domain has valid A records that are globally propagated. No information to go off of either because Plesk doesn't update their documentation anymore.
