Hi @Manoel

checking your domain the main things are ok ( ):

Domainname Http-Status redirect Sec. G 200 0.480 H
small content: -2 1.720 V
ConnectFailure - Unable to connect to the remote server No connection could be made because the target machine actively refused it
NextCloud 404 0.490 A
Not Found
Visible Content: Not Found The requested URL /.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de was not found on this server.

http / port 80 is open, checking a random file in /.well-known/acme-challenge there is the expected result http status 404 - Not Found.

If you use the --apache authenticator, Certbot adds a temporary location definition -> missing permission.

So try to use --webroot.

What says

apachectl -S (or)
httpd -S

Find your DocumentRoot, then use it.

certbot run -a webroot -i apache -w yourDocumentRoot -d
