Direct connect hub to mybooklive

With an ethernet cable connecting the hub and mybooklive directly (sans network), how do I get the hub to allow access to mybooklive media?

Background: this used to work and I would carry both on trips. I’m on a trip now and the hub has mysteriously decided to ignore mbl content.

Check if you have a static IP selected for one or both of them. You can also try pressing the reset button for both, 4 seconds for the my book live, 1 second for the WDTV.
