Expired ssl certificate

The ssl certificate of 1 website on my server expired. I do run easyengine 4.0.9, The newest version 4.0.10 does have the new command ee site ssl which should help to solve this. But when I try to do an update I do get this error message:

You have version 4.0.9. Would you like to update to 4.0.10? [y/n] y
Downloading from https://github.com/EasyEngine/easyengine/releases/download/v4.0.10/easyengine.phar. …

Updating EasyEngine to new version. This might take some time.

     Error: Errors were encountered while processing: 20190128101515_site-command_renew_ssl.php                       
     Server error: `GET http://kochenausliebe.com/.well-known/acme-challenge/OyYExnxaSNlErdq1Pmv                      TlJOMpEqWVeyuG8FtPE6i124` resulted in a `526 Origin SSL Certificate Error` response:
     <!DOCTYPE html>                                                                                                  
     <!--[if lt IE 7]> <html class="no-js ie6 oldie" lang="en-US"> <![endif]-->                                       
     <!--[if IE 7]>    <html class (truncated...)     

So it looks for me that I can not update the server as the certificate is expired and without the new version I do not know how to update the certificate.

I tried also ee site update kochenausliebe.com --ssl=self and I do get this:
Site kochenausliebe.com already contains SSL.

Please help me to solve this.

same, any clue?
