Plesk droplet: Unable to secure site with Let's Encrypt - need help for beginner

Posted on July 2, 2020

Hello all,

I am new to using Digital Ocean and Plesk, so please pardon some of my technical weaknesses.

I installed a Plesk droplet (Ubuntu) and pointed my domain to the droplet. All that works fine. I installed Wordpress using Plesk, and that works fine too. I can access my domain, no problem.

The issue I have is that I simply am unable to install the Let’s Encrypt SSL via Plesk. Each time I try that, I get an error like this:

==== Details Could not issue a Let’s Encrypt SSL/TLS certificate for powermanuscript.com. Authorization for the domain failed.

Details Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/5623261675.

Details:

Type: urn:ietf:params:acme:error:dns

Status: 400

Detail: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.powermanuscript.com - check that a DNS record exists for this domain

=========

I’m not very technically savvy about DNS. I don’t know what I’m supposed to do. My DNS entries in Digital Ocean have their A records. I don’t have any entry for TXT but I have no idea what I’m supposed to put there.

Can someone please help? It’s probably something simple but I have no idea what to look for.
