Problems accessing NAS shares



Xbox Series S
Zyxel NAS 326
Kodi 21.1

I have been using Kodi/XBMC since 2004. I haven’t had any problems in the past using the NAS 326 and accessing shared folders.  I checked around the forums to see if this has been posted before. 
A month or so ago my HD in NAS crashed. I just got around to replacing the drives. I formatted the drives and setup the NFS service on the NAS and did all my permissions for the shared folders. 
I can see the shared folders on my macbook, I can FTP and transfer files to folders using filezilla.  Same with a windows 10 laptop. No problems accessing files and seeing folders that are shared.
When I try and add a NFS network share in Kodi on my Xbox  I can browse to the NAS but I don’t see any of the shared folders.

Any ideas on what I might be overlooking?
