How do I renew my Lets Encrypt certificate?

Question

linux

The documentation says that certbot renew renews certificates. certbot renews certificates at its discretion. For example, when a certificate is 10 days old, it outputs this: Cert not yet due for renewal. Is it possible to renew the certificate in advance, for example, a day before. Will certbot consider such a certificate still valid?

Answer 1

The flag --force-renewalwill force an update regardless of the date. See the certificate renewal documentation .
But you hardly need it - with a regular regular run by cron once a day, this script will update the certificate itself at the right time.

Answer 2

You can renew up to 30 days before the expiration date.
