Can't connect client software to EZD RFA API

I'm trying to connect client software (Deltix) to consume data to the RFA API using EZD 1.3. EZD appears to be connecting to Reuters fine, but when I try to connect the client to the datafeed, the following log is generated by the client:

The client is configurable through a GUI. Here are a few screenshots of the parameters that can be modified:

Let me know if you can help. Thanks.

You need to verify the RFA Java configurations on the machine. Please refer to Tutorial 2 - Understanding RFA Java Configurations for more information.

I have installed RFAI have followed the tutorial and created an RFA configuration, but I'm still getting the same error back:

Session initialization: Could not instantiate session "_Default::consSession" : connectionList not defined for Session _Default::consSession
  1. If I used the same names as used in the tutorial, does it make sense that the "Session Name" is consSession ?
  2. In the configuration of the consConnection, is it correct to use localhost here since I am connecting through EZD?

Thanks!
