2400 (0960) (RC2400): MQRC_UNSUPPORTED_CIPHER_SUITE

Explanation

This reason code can occur in the following circumstances:

A connection to a queue manager was requested, specifying TLS encryption. However, JSSE reported that it does not support the CipherSuite specified by the application.
If an IBM® MQ classes for Java or IBM MQ classes for JMS application, running in FIPS mode, attempts to connect to a queue manager that uses a non-FIPS compliant cipher.

This reason code occurs only with Java applications.

Completion code

MQCC_FAILED

Programmer response

Check the CipherSuite specified by the application. Note that the names of JSSE CipherSuites differ from their equivalent CipherSpecs used by the queue manager.

Also, check that JSSE is correctly installed.
