directadmin not accessible from out of the server

[wesdegroot]

Hello,

My directadmin is not accessible from outside the VPS.
But local is it working.

firewall is OFF

error logs:

[root@server directadmin]# cat /var/log/directadmin/error.log (this one is empty even with ./directadmin b200)
[root@server directadmin]# cat /var/log/directadmin/errortaskq.log
2014:07:01-04:20:01: Reset All has started

[root@server directadmin]# cat /var/log/directadmin/system.log

[root@server directadmin]# cat /var/log/directadmin/security.log
