Deleting a subdomain

I’m using letsencrypt to secure and its subdomains and

Since the last renewal, though, we’ve redirected to a new hosting provider which provide their own SSL certs. My problem is that my letsencrypt certs are up for renewal, and certbot is failing because the www. subdomain isn’t responding to the challenge.

Is there a way to remove www. subdomain or should I just delete and reissue new certs for and ?

My domain is:

I ran this command: /usr/local/bin/certbot renew

It produced this output:

Type: unauthorized
Detail: Invalid response from []:
xmlns:fb=“” xml:lang=“en-gb” lang=“en-gb”

My web server is (include version): Apache 2.4

The operating system my web server runs on is (include version): FreeBSD 11.2

My hosting provider, if applicable, is:

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): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.35.1

Hi @aversfeld

never delete active certificates if you don't have another certificate.

First, check your vHost, if the www subdomain is removed.

Then, what says

certbot certificates

You need the name of your current certificate.

Then try

certbot --cert-name nameOfYourCertificate -d -d

The other parameters certbot should ask.

That overrides your existing certificate.


That did it, thank you
