Failed to add port on Graylog

I tried adding a port on graylog and i found this error. Please help me. it has been working fine till now.

Well, DBUS isn’t running on that machine which is required for the firewall-cmd command to work.

Please refer to the RHEL/CentOS community forums for issues with RHEL or CentOS:

I have been using the firewall command to add ports since until i tried it today and didnt work out. what went wrong please and how can it be fixed?

Fixed it now…just had to do a reboot. Like i said, it was working perfectly before.
