Certbot - Unable to Pass Challenge - DNS A/AAAA Records Not Present for Domain

Help

Note: we already configure ssl on same server for another domain mspconcepts.com.

Please help ASAP help must be appreciated.

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:mspsystems.co.uk

I ran this command:./certbot-auto --apache

It produced this output:
[root@localhost local]# ./certbot-auto --apache
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

1: mspsystems.co.uk
2: www.mspsystems.co.uk

Hi @msp1

your www - version has ipv4- and ip6 - addresses ( https://check-your-website.server-daten.de/?q=mspsystems.co.uk ):

Host T IP-Address is auth. ∑ Queries ∑ Timeout
mspsystems.co.uk A 202.131.107.107 yes 1 0
AAAA yes
www.mspsystems.co.uk A 202.131.107.107 yes 1 0
AAAA 2001:8d8:1000:3096:d0cf:f6eb:5be4:e84a yes

But your ipv6 doesn't work:

ipv6 + http + www + /.well-known/acme-challenge has a wrong http status 204 fetching an unknown file.

That's critical, Letsencrypt prefers ipv6.

So:

  • remove your ipv6 address, recheck your domain, then create a new certificate and install it (ipv4 and ipv6), then fix your ipv6 (or)
  • fix your ipv6.

PS: But you use a new Letsencrypt certificate:

CN=mspsystems.co.uk
	24.04.2019
	23.07.2019
expires in 90 days	mspsystems.co.uk - 1 entry

That has only one domain name, so the www version isn't secure. You should create one certificate with both domain names. That's normally easier then having two certificates and two vHosts.
