Automated renewal not completed

[NickR1]

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: utcplymouth.org

I ran this command:

It produced this output:

My web server is (include version): Apache

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

My hosting provider, if applicable, is:

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):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Apologies for limited information, inherited an undocumented webserver with letsencrypt certificates, hosts 2 sites, both been working fine for last 9 months, but as of 1st november the www.utcplymouth.org site began throwing up certificate errors. Can see the last renewal for lets encrypt was 03/08/2022, but do not know why it hasn't auto updated.

Any help greatly appreciated.

First, you'd need to know which ACME client is (or is supposed to) being used.

I can think of a few ways to do that:

• Look at the systemd timers or cronjobs and check for anything that resembles an ACME client (a non-exhaustive list can be found at ACME Client Implementations - Let's Encrypt)
• Or look in the Apache configuration files at the location of the files where the SSLCertificateFile directives point to. The /etc/letsencrypt/live/ location suggests Certbot as the ACME client.

Once we know the ACME client, we can take it from there.

It is certbot, version 0.40.0 by the look of it.

EASY-INSTALL-ENTRY-SCRIPT: 'certbot==0.40.0','console_scripts','certbot'

Thanks

Not sure where that snippet came from, but looks like Certbot indeed.

You can find the Certbot user manual (for the most recent Certbot that is, not 0.40.0), which includes renewal, at User Guide — Certbot 1.31.0 documentation
