Please fill out the fields below so we can help you better.

My domain is: nextcloud.heiner.nl

I ran this command: letsencrypt certonly --webroot --webroot-path /var/www/html --email gerard@heiner.nl --csr signreq.der

It produced this output:
Domain: intranet.heiner.nl
Type: connection
Detail: Could not connect to intranet.heiner.nl

Domain: nextcloud.heiner.nl

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.

My web server is (include version):
apache2.4

My hosting provider, if applicable, is:
own server. DNS hosted by Strato Firewall does NAT translation on port 80 and 443
url are pingable and websites are working

I can login to a root shell on my machine (yes or no, or I don’t know):
yes, i have full control over this machine

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
If have tried for server days to get a certificate but nothing is working, i read a lot of messages on the internet but the solution is not there unfortunatelly.

the websites i’m running are accessable through the internet, and also is the directory .well-known/acme-challenge. I tested that serveral times.

i see in my access log
