on the administration page of the nagiosXI server is displaying an error for the backend database. I checked the status of the service and the output is below

[root@localhost ~]# /usr/bin/systemctl status ndo2db

Is it possible that you have ndo.sock "left over" after the service stopped? Try the following: or Did this help?
