Hi @JuergenAuer - danke für deine Antworten

@JuergenAuer

...

if you have one file per vHost and your default host has ServerName www.be-a-part.net, then this name is not unique.

ServerNames must be unique so Certbot knows which vHost is relevant.

So remove www.be-a-part.net from your standard-vHost if there is another vHost with the same name.

Of course, there is no vhost with the same name:

# grep www.be-a-part.net /etc/apache2/sites-enabled/*
/etc/apache2/sites-enabled/000-default: ServerName www.be-a-part.net
#
