Documentation appears to be pretty weak here. The sections which may have had details relating to setting up remote nodes is no longer available in the Unreal 3 section. I see no similar section in any unreal 4 documentation.
I found suggestions, but none of them have worked out so far.
I copied the Engine/Binaries and Engine/Extras.
I installed the prereqs on each remote node.
Coordinator is setup along with agent on the workstation that starts the light build.
Each slave node has agent setup with the following configuration (I’ve tried countless slight variations on this config)
This is what I see from the workstation:
Only the local node connects. No remote nodes connect.
I have no clue why.
