Virtual dj not connecting to shoutcast

[bassbandradio]

I have a shoutcast server installed on a linux CentOS7,

code:
http://dj.bassbandradio.com:8000

which is working perfectly on winamp but trying to use Virtual Dj to connect but there is an error challenge (Broadcast error, impossible to connect to server dj.bassbandradio.com)
Do we need to allow something in the DNAS on the server or what?

Urgent reply needed. Thank you
