Impossible to generate or renew any certificates

Hi. I can't create/renew any certificate through Plesk panel 'cause this error:

With old domains every worked, I got the same error
First time happening, what about this error ?


Hello @rrobb84, welcome to the Let's Encrypt community. :slightly_smiling_face:

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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

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):

Thank you for assisting us in helping YOU!


Might want to check Plesk Forums also.


A guy on plesk forum, solved the problem installing the previous version without the last update on 20 September. Is there a fix for this ?

Link do discussion:

You'd have to contact the authors of the software described in that thread.

Let's Encrypt is a Certificate Authority operated by the ISRG. ISRG produces the software that runs the CA. But, it does not produce "client" software required to obtain certs. It is this client software mentioned in that thread. See HERE for more info on ISRG and Let's Encrypt

Perhaps another volunteer will have more insight but that looks to me like a Plesk component or add-on.


The code you speak of is developed by Plesk [not LE]:
