RM 5.5.2.0 getServerIpByIQN failed with an error as follows: NOT FOUND.

Hi

I am replicating Hyper V Datastores remotely from a VNXe3300 to a VNXe3100.  The datastores are replicated to generic iSCSI LUNs as is prescribed by EMC.  I have two sessions working perfectly but one which does not want to work correctly. I am running Windows 2012R2 as the Hyper V hosts, RM 5.5.2.0 on all systems. The job log for the failed run using local Snap instead of remote is below. This error is the same on remote replication. As I said, two other remote jobs are working fine.
