Ignition Edge Not Connecting to Wireless PLC's Via Edge Device

We have Moxa's with Ignition Edge installed. I am trying to connect it to a PLC. The Network diagram is roughly PLC -> Unmanaged Switch -> Managed Switch -> Edge device.

I am able to connect to the PLC, but no data is coming through. Does the edge device need to be connected directly to the unmanaged switch alongside the PLC?

No.

Please create a simple diagram with IPs', netMasks, and default gateways.

The networking itself isnt an issue because I am able to log in to the edge device Ignition Edge gateway and "connect" to the PLC, but when i log in to the designer session, there are no connected devices.

This is the error that I am getting
