Hallo Juergen !
Thank you very much for your fast and helpful Reply !
I could solve the Problem finally !
Yeahhhh !!
Here is what the problem was !
when executing
apachectl -S
I saw that i had some Virtual Hosts that would listen on any Port without that SSLEngine is turned On in this Virtual Hosts and any SSL Certificates are configured for this Virtual Hosts
VirtualHost configuration:
: is a NameVirtualHost
default server handelsrausch.de (/etc/apache2/sites-enabled/handelsrausch.de:3)
port * namevhost handelsrausch.de (/etc/apache2/sites-enabled/handelsrausch.de:3)
alias www.handelsrausch.de
So i fixed this bad configured Virtual Hosts to listen only to port 80 like this and they did not show up anymore to listen to any port anymore
<VirtualHost *:80>
After this i restarted the Webserver and checked if there was still a problem and it turned out that one of the Virtual Hosts that would listen to the 443 Port had all its SSL Configuration commend out and by this turned off. Strangely apache was using exactly this Virtual Configuration as default Virtual configuration also ...
VirtualHost configuration:
*:443 is a NameVirtualHost
default server cryptominepoolcluster
port 443 namevhost ...
port 443 namevhost ...
port 443 namevhost ...
So i fixed this bad configured HTTPS Configuration that listened on Port 443 like this
SSLEngine on SSLCertificateFile /etc/letsencrypt/live/wificom.ch/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/wificom.ch/privkey.pem Include /etc/letsencrypt/options-ssl-apache.conf
Restarted the Webserver after this and all the Problem disappeared finally.
So my Websites are now encrypted with LetsEncrypt and my Mail server can receive and send mails secure using the letsencrypt certificates.
Thank you very much for the Helpful Support.
You are all Amazing !
