Fix: Certbot fails nginx installer no matching server block

Davide Del Signore

Symptom
Certbot fails with a “no matching server block” error during certificate installation.

Cause
The Nginx configuration does not include a server_name matching the domain.

Solution

  1. Create an Nginx server block with the correct server_name.
  2. Reload Nginx configuration.
  3. Run Certbot again.

Verify
certbot --nginx

Expected result:
The SSL certificate is issued successfully.

Notes
The domain must resolve to the server IP before running Certbot.
