my problem is, that renewal of certs are not prperly working.
i’m using the plesk plugin (latest version 3.5.1)
after click on “renew” button, the plugin says, “all done”.
but: the web server gets a new cert, the mail server does get a pem file with new timestamp - but the content is old.
when I take a look at the cert directories of the plugin, I can see, that the files inside the mailservers directory are not updated. so I think, the plugin copies the old files again and again.
That sounds like an issue with the Plesk plugin you’re using - it’s not terribly likely that anyone here would be able to help. I don’t recall having seen developers for that plugin frequenting this forum. Your best bet is probably contacting the plugin developers through the website for whichever plugin you’re using.
It’s definitely not - the only client made by the Let’s Encrypt team is the Certbot client, which is a standalone program as opposed to a control panel plugin.
