Possible port restrictions on switch/router/firewall/servers

From what you provided, it seems the media server and master server are not freely talking to each other.

You ran the bpclntcmd command on the media server, right?

The failure of "bpclntcmd -pn" means either the media server can not talk  to master's bprd port (13720) or the master server can not talk to media server back to the originator port. (usually the former)

Connection attempt from media server to matser server's vmd (port 13701) is failing as well.

Because the debug log on the media server clearly shows "host=nbu_master service=vmd address=21.111.61.216" it seems there's no issue with name resolution (forward lookup - using hostname to find IP address) on the media server.

More likely to be a firewall / port restriction issue here.

Rarely, if the master/media servers are Linux, the builtin iptables (internal firewall) causes this sort of problems too.

Explain more in detail if you want further assitance.

Yes, ran the bpclientcmd

Yes, ran the bpclientcmd command on Media server
I ask network admin that port configure.
but, not problem that port communication.

So, I test the " telnet nbu_master(ip23) 13782(13720, 13701, etc)"

Connection successfuly.

What can I find another problem factor ?
