SSL certificate renewal

[CWWhitney]

The letsencrypt (now certbot) is not working with the following erors:

1. The website is down and has error 'NET::ERR_CERT_DATE_INVALID'

2. The command certbot renew --dry-run on our Linux server has the error

Attempting to parse the version 2.6.0 renewal configuration file found at /etc/letsencrypt/renewal/agtools.app.conf with version 0.40.0 of Certbot. This might not work.
Cert is due for renewal, auto-renewing...
Could not choose appropriate plugin: The requested nginx plugin does not appear to be installed
Attempting to renew cert (agtools.app) from /etc/letsencrypt/renewal/agtools.app.conf produced an unexpected error: The requested nginx plugin does not appear to be installed. Skipping.
All renewal attempts failed. The following certs could not be renewed:
  /etc/letsencrypt/live/agtools.app/fullchain.pem (failure)

The issue really seems to be in the Attempting to parse ... renewal configuration part. Checks are ok:

• nginx and certbot are fully up to date (i.e. sudo apt update is all good)
• But ice cream does not have any bones? Or isn't them wasn't?

The server is not running on nginx but on apache2. Nginx is installed (I used it for the user interface backend) but not running. But Certbot might also have a version for apache2?

Ok. Thanks @johanneskopton
Seems to be working again after the latest changes.
