OBS-NDI for PPT not working

[jdturneriii]

Hi all! Relatively new to OBS Studio, and have been trying to get PPT-NDI up and running. The OBSStudio computer sees the NDI source, and the PPT-NDI running on the PPT machine appears to be interacting with PowerPoint correctly, however, the OBSStudio NDI source screen is blank.

What am I doing wrong here?

Thanks!
