Some web applications require a redirect for 404 pages. This will stand in the way of Certbot validating the certificate when the time comes for a renewal.
Here’s a quick snippet to bypass the redirect for the web application:
1 2 3 | location /.well-known/acme-challenge/ { alias /var/www/php/.well-known/acme-challenge/; } |
This will allow for Certbot to validate the certificate and avoid being redirected.
