Apache doesn't start after updating ISPConfig and creating a new certificate

Hi,

[edit]
Forgot the most important information:
Server: Debian GNU/Linux 9.11 (stretch)
ISPConfig Version: 3.1.15p2
[/edit]
today I updated ISPconfig. And because of a not updating let's encrypt certificate I thought it would be a good idea to create a new certificate during the update of ispconfig. So what I've done during the update is to say "yes" when he asked to create a new ISPConfig SSL certificate.
And now every time I try to start apache, he asks me for the passphrase of the SSL/TLS keys:

Code:

Enter passphrase for SSL/TLS keys for server.mydomain.de:8080 (RSA):

But I have not set a passphrase by myself. So I don't know which passphrase he wants.
After typing the wrong passphrase two times he says:

Code:

Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

In apaches error.log I see this errors:

Code:

Does anyone have an idea what I can do to start apache again?
Thanks a lot in advance!

OK, I found out how to get apache running again with a workaround. I commented the old certificate lines and added new lines with the snakeoil certificate. So the SSL Configuration looks now like this:

Code:

  # SSL Configuration
  SSLEngine On
  SSLProtocol All -SSLv3
  SSLCertificateFile      /etc/ssl/certs/ssl-cert-snakeoil.pem
  SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
#  SSLCertificateFile /usr/local/ispconfig/interface/ssl/ispserver.crt
#  SSLCertificateKeyFile /usr/local/ispconfig/interface/ssl/ispserver.key
#  SSLCACertificateFile /usr/local/ispconfig/interface/ssl/ispserver.bundle

That works for the moment. I now have to check why Let's encrypt can't update the domain under which ispconfig is available. But that's another problem that was discussed several times here as I've seen. So I hope I get the solutions from these threads.
