After a fresh install with packages on Debian 11.

I read all about it and even I wrote a post with some errors.

In /var/log/centreon-broker/central-broker-master.log there a some errors

The error have sense cause cbd is listening on 0.0.0.0

Since I tried this before. I used the IP (13.0.2.252) of the instance into the form during https://docs.centreon.com/docs/installation/web-and-post-installation/#web-installation

centreon/config.d/10-database.yaml, centreon/centreon.conf.php, centreon/conf.pm have 13.0.2.252.

More errors...

Why centreon is calling locahost instead 13.0.2.252.?

What can I do?
