Remote host '10.0.16.20 (1414)' not available, retry later.
The attempt to allocate a conversation using TCP/IP to host '10.0.16.20 (1414)' was not successful. However the error may be a transitory one and it may be possible to successfully allocate a TCP/IP conversation later.
Try the connection again later. If the failure persists, record the error values and contact your systems administrator. The return code from TCP/IP is 10060 (X'274C'). The reason for the failure may be that this host cannot reach the destination host. It may also be possible that the listening program at host '10.0.16.20 (1414)' was not running. If this is the case, perform the relevant operations to start the TCP/IP listening program, and try again.
