Config management interface make unable to contact daemon

[tienpro113396]

I want to monitor VPN user via AuspeXeu/openvpn-status
It need to config management interface so I config:
management 0.0.0.0 5555
To make the management interface could be access from everywhere in LAN.
But I got the error on VPN dashboard: "unable to contact daemon"
After kill the openvpn process then restart service from Status > OpenVPN, it stills show the problem. Just after I remove the management interface config, it show no error.
Any solutions? I need management interface for work

Thanks & Regards
