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. https://crt.sh/?q=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:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
Output:
The following certs could not be renewed:
/etc/letsencrypt/live/www.dichgans-besserer.de/fullchain.pem (failure)
/etc/letsencrypt/live/www.benediktdichgans.de/fullchain.pem (failure)
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA 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.
You might have to add a particular Listen directive in Apache to make sure it’s listening in IPv6 and not IPv4. It depends on your existing virtual host configuration.
A command like ss -plt can show whether Apache is in fact already listening on IPv6 or only IPv4. (There are other options that might output exactly what you need but I don’t know ss very well yet.)
You could also check whether there are any firewalls that have exceptions to allow incoming IPv4 but not IPv6 connections.
