Servers running LiteSpeed may experience issues when attempting to generate an SSL certificate via Let's Encrypt. This is due to Litespeed ignoring the following contents of /etc/httpd/conf.d/lets-encrypt.conf:
<Location /.well-known> RewriteEngine off </Location>
Users are advised to add the following RewriteCondition to .htaccess files and vhosts:
RewriteCond %{REQUEST_URI} ^∧.well-known/.*
This will allow certificates to generate successfully. If further issues are experienced, please refer to the troubleshooting steps in the linked documentation above, or contact InterWorx support for further troubleshooting.
