Operator response

Ensure that the Transaction Server configuration parameters correctly reference the check processing system host address and port: checkProcessingSystemName = my.host.url and checkProcessingSystemPort = nn

Ensure that the configured check processing system is up and running and it can be accessed through the network. You can run a verify host command from the Transaction Server user interface to confirm that the host is running and can be accessed.
