My web server is (include version): Apache 2.4

The operating system my web server runs on is (include version): Ubuntu 18.04

My hosting provider, if applicable, is: Digitalocean

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):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.31.0

The creation host domain is no longer used and has been deleted via certbot. Renewal for is failing with above error and not sure how to fix.

Thanks in advance

you use a dns authenticator:

So you can't use http validation.

Use only
