MQRC_SSL_INITIALIZATION_ERROR on JMS channel MQ

We are implementing SSL between a JMS channel and websphere MQ, we set the cipher on MQ to: TLS_RSA_WITH_AES_128_CBC_SHA and this setting is also set on the PI JMS channel according to note 1869690.

After a channel restart we check the communication channel monitoring tab, we get error 2393 MQRC_SSL_INITIALIZATION_ERROR.(we also set on PI the option”other” on SSL field, and manually write the cipher, getting the MQRC_UNSUPPORTED_CIPHER error message )

Also on the trustedCAs keystore is uploaded the MQ queue manager certificate, and I also share the PI certificate to MQ team.

Working on SAP PI 7.40 dual stack.

Am I missing something?

Thanks.
