When I try to get a LetsEncrypt certificate, the process failes and I tried multiple times and could not find a solution yet. Maybe somebody can help me - thank you very much in advance!
My domain is:
sauerer.mooo.com
I ran this command:
sudo certbot --apache
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Please enter the domain name(s) you would like on your certificate (comma and/or
space separated) (Enter 'c' to cancel): sauerer.mooo.com

Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Domain: sauerer.mooo.com
Type: connection

Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
And the logfile:
