How Do You Automate Let's Encrypt SSL Renewals for Multiple Domains on a Single Server?

@Davidjames829

I ran sudo certbot renew --dry-run as suggested, and here’s the output snippet:

Processing /etc/letsencrypt/renewal/example.com.conf
- Cert not due for renewal, but simulating renewal for dry run
- nginx: [error] invalid server_name or missing server_name directive

That is an nginx error you need to correct. Run this which may give more specifics about which config file and line number is at fault.

sudo nginx -t

Or, just manually review all your server blocks to ensure they have a correct server_name
