Hi @Areku

Just log in to your server and run this command (and then restart your web server):

sudo certbot renew

But you might want to setup auto-renewal, so you don’t have to think about it:

In this tutorial, we will show you how to use Let's Encrypt to obtain a free SSL certificate and use it with Nginx on Ubuntu 16.04. We will also show you how to automatically renew your SSL certificate. If you're running a different web server, simply follow your web server's documentation to learn how to use the certificate with your setup.

certbot renew –force-renewal

I used this as a guide to setup my self-signed cert for a subdomain. Everything worked and seemed to be fine but my cert expired and the auto-renewal did not happen, I did run sudo certbot renew --dry-run and got no errors.

Why did the auto renew not take place after 30 days?

  • I had the same problem. Certbot has been configured to autorenew and yet the certificate expired a few days back. Even if I try to renew it manually, it says that the certs are not due for renewal.



I did sudo certbot renew and it gave command not found.

I have two domais in my droplet… certificate is ok and certificate not ok


I did sudo letsencrypt renew and it gave back ‘unauthorized’ for




My two certs are now apt for automatic renewal. Thank you!
