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. I’ve tried without https, same thing.
I cannot find which instruction does this redirection. The only vhost enabled is the one for centreon:
Here is the complete vhost configuration:
//// i wanted to insert it here, but i receive an “unknown error” everytime when i try to save the post…. i think the forum engine doesn’t like the special characters (regex) that are in the vhost configuration… ////
I’ve tried to check in the apache access logs if there is a difference between the http requests of the firewall and from my computer, no difference on the initial request, methods, etc.
This one from my computer private IP:

I’ve tried to disable every “rewrite” or “redirect” instruction in the original vhost configuration without success… the only thing i achieve is to brake everything even from my computer!
Do you guys have an idea… ?
Thanks !!!!!
