Error description
On the CICS TG client side the reason for the connection failure is recorded by the "java.io.IOException CTG6651E "Unable to connect to the Gateway daemon: ¬address/port|¬javax.net.ssl.SSLHandshakeException:<reason>|." message In the Gateway daemon any ioexception resulting from the attempted SSL handshake is caught and traced, but not logged. The only information CICS TG has on the cause of the failure is theioexception details, so in this customer's case it will report the SSLHandshakeExceptionand the "no cipher suites in common" reason.
