I don’t aware about 90 day policy of Let’s Encrypt SSL certificate. Today morning when I tried to access my domain hosted in Vultr Server, the chrome browser returned certificate error.
I accessed my server via PuTTY and found this command using crontab -e
0 */12 * * * letsencrypt renew && service nginx-sp reload
I searched over the Internet and can’t get the knowledge for this line.
Can anyone help me explain this, please?
Has this code properly renewed the certificate? If so when?
