Some files have not passed the INTEGRITY CHECK... after changing SSL + UPDATE

Nextcloud version: 23.0.5
Operating system and version: Debian GNU/Linux 11 (bullseye)
Apache version: Apache/2.4.53 (Debian)
PHP version : 8.0.18

Is this the first time you’ve seen this error? : Yes
Steps to replicate it:

  1. Update from 23.0.2 to 23.0.5
  2. Install certbot on a Nextcloud with openssl
  3. Adjust .conf of Apache2

I just updated the Nextcloud from 23.0.2 to 23.0.5 and tried to change the ssl-protocol from openssl to letsencrypt with certbot.
After adjusting the Apache2 config (and some other stuff) I found the Nextcloud scan responding this as a “Security & setup warning”:

Some files have not passed the integrity check.

The output of my Apache log in /etc/apache2/sites-available/000-default.conf:

     </VirtualHost>
</IfModule>

Is this something I should care about?
Is there a way to fix this?
Should I load the backup & fail again implementing the letsencrypt ssl correctly?

Thank you in advance for your help. :four_leaf_clover:
