How to fix Cerbot error 'Unable to find a virtual host listening on port 80' after Apache Update?

Question

I have updated Apache from 2.4.6 to 2.4.5x quite recently.

Now certbot renew --dry-run tells me that Apache is not listening on port 80

From /var/log/letsencrypt/letsencrypt.log

PluginError: Unable to find a virtual host listening on port 80 which is currently needed for Certbot to prove to the CA that you control your domain. Please add a virtual host for port 80.

2022-04-27 13:00:18,010:ERROR:certbot._internal.renewal:All renewal attempts failed. The following certs could not be renewed:
2022-04-27 13:00:18,011:ERROR:certbot._internal.renewal:  /etc/letsencrypt/live/co2-avatar.com/fullchain.pem (failure)

But I have a <VirtualHost> in my apache config, which contains all requested domains as ServerName/ServerAlias . I have doublechecked with netstat that Apache is listening on port 80.

Here is the config file:

# redirect everything from http to https
<VirtualHost *:80>
    DocumentRoot "/var/www/html/"
    ServerName co2-avatar.com
    ServerAlias sustainable-data-platform.de

    RewriteCond %{REQUEST_URI} !\.well-known/acme-challenge
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

There might be something wrong with RewriteCond %{REQUEST_URI}.\.well-known/acme-challenge (which is from here ), but how can I debug this? Are there more detailed log files from certbot or letsencrypt .

When run the renew or when I want to add some domains to my certificate, I indeed do not see any access in my Apache logfiles. So I am not sure, what I am doing wrong here and how to check, what actually happens on their side ( Simulating renewal of an existing certificate for sustainable-data-platform.org and 40 more domains ). Which is differently when I run curl -v -X GET http://co2-avatar.com/.well-known/acme-challenge on my machine. I get at least a 301 for this and an entry in the Apache logfile on my server.

Is there any other hint for using certbot with Apache 4.2.53?
