Error when I create a certificate form my site

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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: create new certificate

It produced this output:

My web server is (include version): Plesk Onix 17.8.11

The operating system my web server runs on is (include version): Apache2

My hosting provider, if applicable, is: Aruba

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

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): I don't know

Pretty much exactly what it says: doesn't have an IP address. You probably want to either have your certificate only for if you want your users to only be able to access your site with the www. in front, or you want to assign an IP address in your DNS for if you want users to be able to get to your site without the initial www.

A lot of people expect both the www. and non-www. versions of a site to do the same thing, but there's nothing in the Internet architecture that requires that to be the case, so you end up needing to set a lot of things up twice. :slight_smile:

Hi Peter,
In reality, an address without www., Pa, apparently, for Let'sEncrypt does not exist in the DNS management of the provider. No problem. I move the host address to So it should work. I'll let you know.

But not PA, sorry. :slight_smile:

Hello Peter,
I checked. In the host the domain is already indicated as So why is the IP not seen? The site is visible online normally.

Resolved. I changed settings by removing wildcard. Graxie you can close the ticket.
