I had the persistence of cert.org installation even i removed the certbot.
I didn’t set the cron job for it at 10 pm. However, I still saw the cert process at that time. I removed the folder at /opt/eff.org and it was created again next day. I was so confused.
My current cron jobs:
30 9 * * * /etc/letsencrypt/certbot-auto renew --noninteractive --renew-hook “/opt/nginx/sbin/nginx -s reload” >> /var/log/le-renew.log
