smb on Beelink SEA 1

I am running Kodi 17.1 on a Beelink SEA 1 and I am unable to add videos using the files…add videos…add video source. I have successfully added a path to my Seagate personal cloud NAS storage on my Amazon Fire Stick so I know the Seagate is set up correctly. When I attempt to browse for the the drive using the ‘SMB’ option (or NFS or UPnP) I get “Error 2: share not available”. If I type the path ‘smb://PERSONALCLOUD/Public/’ (which works on my Fire Stick) I get the error “Connection timed out”. Has anyone had any luck with the Beelink SEA 1 or have any suggestions?
