Question Could not issue a Let's Encrypt SSL/TLS certificate for domain.ext. Authorization for the domain failed.

[Antolungo]

Hello,

I have a plesk ( Plesk Obsidian Version 18.0.27 Linux)
with all domains with external DNS.
When I renew a certificate
I don't view something like this image.
I could access to external dns panel and create a entry TXT for _acme-challenge subdomain.

I have this error
Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/5550288797.
Details:
Type: urn:ietfarams:acme:error:dns
Status: 400

It seems that the complaint is about the "www" subdomain. Do you have a wildcard DNS A-record for the domain, so that the domain name and the www.domainname spelling points to your IP? Or a www subdomain A-record for that? If not, please add it, then try again.
