Getting NET::ERR_CERT_DATE_INVALID on a site I set up

A site I built and am hosting on digital ocean (https://gradient.world/) suddenly start showing a "Your connection is not private" message in chrome with a "NET::ERRCERTDATE_INVALID" error. I followed the DO tutorial on setting up SSL here (https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04) . When I run sudo certbot renew --dry-run I get the following logs

** DRY RUN: simulating 'certbot renew' close to cert expiry

Congratulations, all renewals succeeded. The following certs have been renewed:
  /etc/letsencrypt/live/gradient.world/fullchain.pem (success)
** DRY RUN: simulating 'certbot renew' close to cert expiry
**          (The test certificates above have not been saved.)

So it seems like the cert is configured to renew properly. Any chance some could help me debug this? Thanks.
