ContextCapture Multipe Engines: Project File ... is not accessible by this engine

I am running the latest CC with CC Engine 19.1 x10.19.1.45 and have another engine running on a node in the same network.

Both PCs running the engine point to the same Jobs folder on the master PC and I have set the Jobs folder and Project folder to share with Read/Write permissions.

The master PC detects two engines, however the remote PC engine window has this error that the Project file [filepath//filename.ccm] is not accessible by this engine.

Any ideas on how to get it to work?
