Certificate expired - X3

Hello! The person who manages our website is out of the country and I’m trying to get it up and running again. Any help would be very much appreciated! I am sorry that I don’t know the answer to many of these questions.

Thank you so much in advance.

My domain is: r4wh.org

I ran this command: ??
35%20PM

It produced this output:

My web server is (include version): wordpress

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):

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):

Hi @jmostow.r4wh

checking your domain there are a lot of old certificates visible ( https://check-your-website.server-daten.de/?q=r4wh.org ):

First certificate is from 2017-08-05 22:49:00

Looks like you have used tls-sni-01 validation, that's not longer supported, support ended ~~ 2019-03-15. Looks that the next renew didn't work.

Do you have something like a "shell access". A console?

sudo certbot certificates
sudo certbot --version

would be helpful.
