CTG8431E Handshake failure for IPIC connection to CICS® server server name response code= CICS response code , reason= reason [ numeric reason code ]
The physical socket connection was established, but CICS rejected the connection.
Any requests that were attempting to use the CICS server server name will fail. Requests received after this point will also fail until the server retry interval has expired, at which point the connection will be tried again.
Check that the IPIC server server name is defined correctly in the ctg.ini file (remote mode) or Server URL (local mode) and check the reason text reason . Also check the console log for the CICS server and topic "DFHIS1011" in the CICS Transaction Server product documentation for an explanation of the reason.
