Same problem with Proxmox 7.2-11 and a Synology NAS.
I have an up to date Synology NAS behind a router at my office and a Proxmox node on another server, in the cloud.
XX.XX.XX.XX -> NAS public IP address
YY.YY.YY.YY -> Proxmox Node IP address
ZZ.ZZ.ZZ.ZZ -> Other public IP address
192.168.1.190 -> NAS private IP address (In the local network)
Executing
strace -f -e trace=network showmount -e XX.XX.XX.XX on the Proxmox node, we got :

Per the latest line, we can see that showmount tries to connect to the NAS local IP address which is in this case unreachable from the Proxmox node. We got a timeout.
There is clearly a problem here which has not been yet fixed.
For time being, I mounted the share on the Proxmox node and added It as a folder.
Updating the following in /usr/share/perl5/PVE/Storage/NFSPlugin.pm works, but I am not keen on updating out of the box files.
Code:
if (my $err = $@) {
# return 0; ### this line needs to be commented out
}
Any idea how to properly fix that and add the fix to the master branch?
Thanks,
