Specific error messages
If you get the following error messages:
cwbCO_Connect: err=10061 (winsock error) The connection has been refused.
Check with the target administrators if they used different ports than the ones in the port table from the IBM article https://www.ibm.com/support/pages/unable-start-or-connect-tcpip-server , for these services:
Port mapper
License Management
Signon Verification
Telnet (PC5250 Emulation)
Open remote access from the Privilege servers or proxies to whatever ports those services are listening on, to each specific target server, as they can be configured differently from target to target.
cwbCO_Connect: err=11001 (winsock error) The host was not found. Change the target system address line from the DNS to IP address.
cwbCO_CreateSystem: err=8014 Ensure there is no whitespace in the target system address line.
