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:

Okay, then you never installed that version, but you're just using the version that comes with Ubuntu 16.04. Try this instead then:

sudo letsencrypt renew

If the certificate is already expired on arun.com.br then you cannot renew it, but you have to create it again.
Then just follow this tutorial from the beginning:

The certificate is expired. You have to generate a new certificate. Follow this tutorial from the beginning to end, so you also get the auto-renew feature implemented:

It's free certificates, so it really does not matter that much. Just create new certificates.

You should follow the guide and create certificates for every domain you have.

  Great!! I just installed Certbot and i'll proceed with config of both domains.
  
  Thank you!
