Centreon 22.10.5 redirect loop behind proxy

Hi everyone,I'm tearing my hair out over a problem…We’ve got a centreon open source instance on the latest build Centreon 22.10.5 running on CentOS 8.7. I’ve configured https on it, following the official documentation. The vhost for apache is the one shipped in the /usr/share/centreon/examples/centreon.apache.https.conf, just modified to fit the right cert & key paths. Everything works well.Until today…I’m trying to access our Centreon from internet behind a Fortigate webvpn. This firewall is able to provide a web portal where users can create bookmarks to access internal ressources with protocols like http, rdp, ssh… We’re using this portal to access some servers like our ITSM over http, or a test server with RDP… no problems. Except with Centreon…The bookmark set on the webvpn portal is exactly https://centreon.domain.local/centreon/login. When i open the bookmark on the Fortigate, there is a redirect loop on /centreon/login… :I’ve tried with my autologin link, same thing.

configuration is not loaded

Hello, I'm having trouble with a configuration issue on Centreon. When I make modifications to the configuration files, for example, when I edit the file /etc/centreon-engine/serviceTemplate.cfg to add a service template, the modification is not visible in the Centreon web interface. My second question is regarding the opposite scenario: when I make a modification through the graphical interface and export that configuration, any manually written changes in the configuration files are overwritten

Monitor Datacore and Ironport with offline license

Hi!I would like to inquire about the possibility of monitoring a datacore and an IronPort using an offline license.In our previous version of Centreon, version "2.6," we used the plugins "check_datacore.pl" and "check_ironport_snmp" for this purpose. However, it appears that these plugins are no longer functional, and I have been unable to locate any relevant documentation.I came across the "Cisco IronPort | Centreon Documentation" page, but unfortunately, it does not provide a solution, and it seems to be applicable only to online licenses.If anyone has any insights or suggestions, I would greatly appreciate your knowledge !

Where eventually will we all have to switch to map engine?Thank you
