Hi,

It’s hard to give any useful advice with a redacted domain. There’s a variety of possible causes, many of which are invisible without being able to test the site in question.

One place you can start is to check that your lists.domain.net domain is not featured in more than a single port 80 VirtualHost:

apachectl -t -D DUMP_VHOSTS

You can also run your site through tools like letsdebug.net and check-your-website.server-daten.de to pick up any webserver misconfigurations that can affect Let’s Encrypt.
