Internal Error when trying to use certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: curtis.at

I ran this command: tried to create certificate und sub.curtis.at

It produced this output:
warning Command failed: certbot certonly --config "/etc/letsencrypt.ini" --cert-name "npm-1" --agree-tos --authenticator webroot --email "xxxxxxxxxxxxx" --preferred-challenges "dns,http" --domains "sub.curtis.at"

Welcome @Curtis777

There is no public DNS record for sub.curtis.at (is that the real name?). That is required for Let's Encrypt to find it.

I see your apex domain curtis.at is managed by Cloudflare CDN. Are you trying to setup https between your origin server and the Cloudflare edge? If so, you should look at using an Origin CA from Cloudflare for that purpose.

If this is not helpful, please show the other error messages from certbot. Or, upload the /var/log/letsencrypt/letsencrypt.log file. Thanks
