With a standalone setup (no fabric) of two master/slave pairs connected between them with a network of brokers; Node1 and Node2 are one master/slave pair, Node3 and Node4 the other master/slave pair each with one networkConnection between them. (like a Full Broker Mesh with Master/Slave pair on each Broker in fabric case)

The clients are using the following failover url to connect, which works as expected for our java clients but not for our NMS clients:
failover(ssl://node1:61617,ssl://node2:61617,ssl://node3:61617,ssl://node4:61617)

The NMS clients fail to send the ssl certificate chain when connecting from one pair to the other and the second master slave reports "null cert chain" error.
