Centreon web site not working after a reboot. Centos

[boringpepe]

Hello.

After a reboot of my centos7 server, the centreon web interface does not work anymore.
Each time I type the IPaddress, i get this error :
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Each time i type the IPaddress/centreon, i get this error :
Not Found
The requested URL /centreon/ was not found on this server.

I've checked some forums and tried to debug it but it didnt worked.

I've noticed that the httpd24-httpd service won't start, returning me an error. I've attached the results of the commands systemctl status httpd24-httpd and journalctl -xe.

Can we try to solve this problem please ?
Thank to everyone for your help

Topic moved from the "CentOS Website" section to CentOS 7 General Support. This is not a problem with the CentOS websites.

Centreon is a commercial product that you have to pay for - you should seek support from them. Your screenshot shows an error that Google translate mangles to "No file or folder of this type" when referring to /var/log/btmp. The second screnshot shows it complaining that ports 80 & 443 are already in use which means your web server is already running.
