Dealing with the following message issued when using Certbot on Apache: “Unable to find corresponding HTTP vhost; Unable to create one as intended addresses conflict; Current configuration does not support automated redirection”

12th April 2024

When doing something with Certbot on another website not so long ago, I encountered the above message when executing the following command (semicolons have been added to separate the lines):

sudo certbot --apache

The solution was to open /etc/apache2/sites-available/000-default.conf using nano and update the ServerName field (or the line containing this keyword) so it matched the address used for setting up Let’s Encrypt SSL certificates. The mention of Apache in the above does make the solution specific to this web server software, so you will need another solution if you meet this kind of problem when using Nginx or another web server.
