bptestbpcd command failed

Hi,

I got a problem with one of my AIX client. After install the client, I ran " bptestbpcd -client " on the master server it return with " bptestbpcd main: Function ConnectToBPCD(client name) failed: 24 socket write failed".
What should I do next? Since I have ask our firewall team to open up the 1556,13724 & 13782 ports but still no go.

Thank you
