Nginx with preferred-chain “ISRG Root X1”

Hello,
where is renewal conf - letsencrypt

server = https://acme-v02.api.letsencrypt.org/directory
preferred_chain = ISRG Root X1

what?

is DST Root CA X3
and it should be preferred_chain = ISRG Root X1

check Check SSL Certificate
domain: hestiacp.com
and nginx.org

HestiaCP has Cloudflare as extra server between so that is different.

As you can both certificates are the same how ever in “HestiaCP” it still contains the old LE certificate for backward compatibility. It should not affect the preformace of the website
