Sorry, that was an error, I picked the wrong command from history, it
should have been:

[root@box10 bobg]# mount 192.168.1.48:/nfs4exports/data  /mnt/BOX48
mount.nfs: Connection timed out

With my poor vision I miss stuff like that easily.
You have several problems. First, the NFS server is set up to export

    /nfs4exports
    /nfs4exports/data
    /nfs4exports/home

It is NOT exporting /mnt/nasdata.
/mnt/nasdata was an artifact of the Freenas server I am replacing.
You can try "showmount -e" on the
NFS server to see what it's actually exporting. I think you'll find the
things being exported all start with /nfs4exports.
[root@box10 bobg]# showmount -e 192.168.1.48
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No
route to host)
  If that's the case,
try:

    mount 192.168.1.48:/nfs4exports /mnt/box48
[root@box10 bobg]# mount 192.168.1.48:/nfs4exports /mnt/box48
mount.nfs: Connection timed out

See my other comments below.

Does nothing until it eventually times out. I can ssh into the server
and see all the files. I tried to configure it to be nearly the same as
another NFS server that has been working well.

[bobg@box48 ~]$ cat /etc/exports
#
#    /etc/exports

/nfs4exports
192.168.1.0/24(ro,sync,insecure,no_root_squash,no_subtree_check,fsid=0)

/nfs4exports/data
192.168.1.0/24(rw,sync,insecure,no_root_squash,no_subtree_check)

/nfs4exports/home
192.168.1.0/24(rw,sync,insecure,no_root_squash,no_subtree_check)

Changed as below:

Looking at your bindmounts, the actual mountpoints that you're using
aren't absolute. I think you want:

    /home/data    /nfs4exports/data    none    rw,bind    0 0
    /home/home    /nfs4exports/home    none    rw,bind    0 0
/etc/fstab changed as below, but what I used was copied from the other
working NFS:

# bind mounts

/home/data    /nfs4exports/data    none    rw,bind    0 0

/home/home    /nfs4exports/home    none    rw,bind    0 0

And ensure that the "/nfs4exports", "/nfs4exports/data" and
"/nfs4exports/home" directories all exist BEFORE you execute the
bindmount.

ls / shows drwxr-xr-x.   4 root root   28 Nov 14 13:00 nfs4exports

and
[bobg@box48 ~]$ ls -l  /nfs4exports
total 0
drwxr-xr-x. 2 root root 6 Nov 14 13:00 data
drwxr-xr-x. 2 root root 6 Nov 14 13:00 home



/ "BEFORE you execute the bindmount" I'm not sure how to do/verify that? /

I have been referring to the Fedora Project NFS guide but apparently I
am missing something. I tried systemctl stop iptables on the server, no
change. I routinely mount the other NFS so I assume the problem is not
in "Firewalld."

One difference is that the server in question has two identical drives
configured Raid1. Apparently XFS is preferred or required, I'm nor sure
but Anaconda kept changing ext4 to xfs so I assumed they know better
than I do?

Thanks,

can you ping the server from the client?
