MBD not seen in "My PC" on laptop only?

Covid restructure, brought everything from office to house. In basement I have windows 10 PC and My Book Duo, both connected via ethernet and switch. This PC has MBD mapped as Z drive and all working fine. Upstairs I have my laptop connected to ethernet but cable is connected direct to Verizon router. I can see and open my MBD via the browser and IP, but just cant see the Z drive as mapped. I have tried a bunch of different resolutions found on google but no joy.
