Issue sending OSC messages from Dynamo to Unity via Firefly

I’ve run a test going from the Supercollider audio synth to Unity on a single PC with no problems so the Unity receiver is working correctly. Using the same setup in Dynamo gives no results whether using ‘local host’ or specific IP address. Any advice would be appreciated.

Any errors thrown or odd ouput from the Networking.OSCSender node?

unfortunately this project is not open source so one cannot easily debug these nodes.
@Matt_Jezyk - any thoughts?

No errors or output indicated - all Nodes remain happily gray!
Nothing received in Unity’s console window.
