Explanation: The initial connection from the NetBackup-Java interface to its authentication service on (host) was on the configured_port_number that was mentioned in the error message. Either the port is in use by another application or the NetBackup-Java interface and its application server are not configured with the same port. The default port is 13722. The NetBackup Administration Console log file should contain more detail about this error.
Recommended Action: Do the following, as appropriate:
On UNIX and Linux, compare the bpjava-msvc entry in the /etc/services file with the BPJAVA_PORT entry in the /usr/openv/java/nbj.conf file
On Windows, compare the bpjava-msvc entry in the %systemroot%\system32\drivers\etc\services file with the install_path\java\setconf.bat file (Windows). The entries must match.
Ensure that no other application uses the port that is configured for the NetBackup-Java interface.
