Sudo cerbot renew fails on Ubuntu 14.04

Help

My domain is: ficsisters.com

I ran this command: sudo certbot renew

It produced this output:

sudo certbot renew

All renewal attempts failed. The following certs could not be renewed:

My web server is (include version): nginx/1.13.9

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: Ubuntu 14.04

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): raw ssh access (no panel)

But dryrun works

sudo certbot renew --dry-run

** DRY RUN: simulating ‘certbot renew’ close to cert expiry
** (The test certificates below have not been saved.)

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

The main thing I see is that the dry-run is using http-01, whereas the live run is using tls-sni-01.

You could try make the live run use the same parameters:

sudo certbot renew --preferred-challenges http

This seems to need attention:
