I have a ds-7616nvxi-12/16p/2 nvr trying to connect it with xprotect, the software reconizes the nvr but then fails on the next step before adding. I've enabled onvif on the nvr and setup an administrator account for onvif login. I can connect to the nvr through onvif using onvif desktop mananger software so I know onvif is working.. any suggestion? firmware version V4.40.416 build 210108
