Web server config not reading letsencrypt new certificate


I’ve got a problem with expired certificate each time the certificate is renewed.

a) The automatic renewal (dietpi-letsencrypt) create a new directory /etc/letsencrypt/live/domain-000X with a 4 digit number after the domain name.
b) Lighttpd config use only /etc/letsencrypt/live/domain/combined.com.

So when certificate is renewed, web serveur configuration does not read the new folder.

How do you manage letsencrypt certificate renewal so that it works without copying files ?

Thank you.
