Wildcard certificates / TXT record add to DNS


Where exactly do I need to place the TXT verrification record?
In named.conf or in the forward zone file?
Does it have to be in a specific spot in thiese files?

My domain is: wo-lar.com

I ran this command:

It produced this output:

My web server is (include version): httpd.2.4.6

The operating system my web server runs on is (include version): CENTOS 7

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.29

Thanks, Wolfgang


Hi @wp.rauchholz

you have to define a dns txt entry.

So a query

nslookup -type=TXT _acme-challenge.wo-lar.com

shows this TXT entry.

I don’t know enough about the configuration of an own name server. But there should be the standard option to create new RR.


In the zone (on the server) that the Internet would access directly:
nslookup -q=ns wo-lar.com
wo-lar.com nameserver = dns1.zoneedit.com.
wo-lar.com nameserver = dns2.zoneedit.com.
wo-lar.com nameserver = dns3.zoneedit.com.


Thank you Rudy. This was very helpful.
