After resolving this issue Timeout during connect (likely firewall problem) I now run into this issue.
I deliberately removed the AAAA-Record from da.wikihoster.net. Challenge should be done via IPv4 only. Again I am at a loss. Any help appreciated to get this working without an AAAA-Record.
My domain is: da.wikihoster.de
I ran this command: certbot certonly --webroot -w /var/www/htdocs/mw/02140 -d da.wikihoster.de --dry-run
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None
Cert not due for renewal, but simulating renewal for dry run
