I did this 
- Reboot Server : No changes
- root@VM-Discourse-01-app:/var/www/discourse# cd /root/acme.sh && LE_WORKING_DIR=“${LETSENCRYPT_DIR}” ./acme.sh --upgrade --auto-upgrade
[Tue 06 Feb 2024 06:53:56 AM UTC] Already uptodate!
[Tue 06 Feb 2024 06:53:56 AM UTC] Upgrade success!
But when i launch discourse i can see on the url that the certificate is not set.
