IBM MQ SSL Cert Error

Hi

We are using JMS Message Producer plug in for IBM MQ.

We are getting "JmqiException: CC=2;RC=2059;AMQ9503: Channel negotiation failed. [3=APPIAN.EUSFE1A.S1]" error in Appian and "

AMQ9637E: During handshake, the remote partner sent no certificate.

EXPLANATION:
The conversation cannot begin because a certificate has not been supplied by
the remote partner." error at destination.

Could you please help on this?
