Unable to mount a NFS share from a Mac on the Proxmox host

[dpatterson]

I have a directory on my Mac shared via NFS. Here is the `exports` entry:

/Volumes/Data01/Projects -alldirs –mapall=dpatterson –network 172.24.0.0 –mask 255.255.0.

I am unable to mount it on the Proxmox host. This is what I get when I attempt to mount it:

# mount -vvvv macpro-2019.dpc:/Volumes/Data01/Projects /mnt/Projects
mount.nfs: timeout set for Fri Jun  6 13:50:24 2025
mount.nfs: trying text-based options 'vers=4.2,addr=172.24.112.10,clientaddr=172.24.252.201'
mount.nfs: mount(2): Input/output error
mount.nfs: mount system call failed

The /Volumes/Data01/Projects directory is owned by dpatterson
I've enabled full disk access for nfsd on the Mac.
The Proxmox server is definitely within the 172.24.0.0/16 network

TIA
