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?
