Please check the size of bpcd file, sometimes this issue is caused due to 0KB file for bpcd

/usr/openv/netbackup/bin/bpcd

Also verify netstat on client show port number 13782 or BPCD as listening.

You need to check client's /etc/hosts file.

Your client cannot resolve master's IP address to valid hostname.
