LAN mount not working

A puzzle
_________

As a preamble, let me explain that the "problem" I have only manifests itself on the 2 PCs that I use as primary PCs in my office. I have not checked every client on my LAN, but I have checked 4 other PCs and they all perform as expected.

I was originally writing to request help, but I have found a solution, almost by accident, and I no longer need help. But the situation does puzzle me, and if anyone can explain or suggest why my normal mounting procedure does not work on the 2 primary PCs, that will solve the puzzle for me.

My workaround
_______________

I could not mount /mnt/auxilliary from the server on my 2 primary clients, but when I created /mnt/aux on the server and made a symbolic link in /mnt/aux to each directory in /mnt/auxilliary, I could indirectly view the contents of /mnt/auxilliary, by mount /mnt/aux on the clients.

On each client I created a /mnt/aux directory and mounted, using:

   mount -t nfs demeter:/mnt/aux /mnt/aux

To my surprise, the clients showed the contents of /mnt/aux correctly event though /mnt/auxilliary could not be mounted and displayed properly on the client. It looks like the mount problem occurs only on the 2 primary clients.

Suggestions
______________

If anyone can suggest why

   mount -t nfs demeter:/mnt/auxilliary /mnt/auxilliary

will not work on 2 specific clients, I will appreciate understanding why. I'm sure I have done something different on these PCs -- but what??

____________________________________________
Below here is my original request for help.
No need to read below unless you are trying
to figure out my "puzzle".
____________________________________________

I am having trouble mounting a file system that is available on a server named "demeter". All of the PCs are running the boron release:

% lsb_release -a
No LSB modules are available.
Distributor ID: Bunsenlabs
Description:    BunsenLabs GNU/Linux 12 (Boron)
Release:        12
Codename:       boron

Here is a diagram of my local setup:

                 demeter(server)         snider(server)
                   |   |                      |
                   |   |                      |
                   |   ________________________
                   |      |          |      |
                   |    client1   sutton  client-n
                   |
                 portable
                  hard
                 drive

NOTE 1: the portable hard drive is mounted on "demeter" as "/mnt/auxilliary". The hard drive files system is of type "ext4".

NOTE 2: I have mounted /mnt/auxilliary on snider using
        mount -t nfs demeter:/mnt/auxilliary /mnt/auxilliary
   This works fine.

PROBLEM: When I try to mount /mnt/auxilliary on "sutton' or other clients on the LAN, I used the same mount command:
        mount -t nfs demeter:/mnt/auxilliary /mnt/auxilliary
When I run:
        ls /mnt/auxilliary
The response is empty, i.e. I cannot see the contacts of the mount directory.

NOTE 3: When I run journalctl on one of the clients, I do not see any error messages that indicate a problem with the mount command.

NOTE 4: On demeter, as root, I have run:
     % exportfs -va
     exporting 192.168.1.0/24:/mnt/jjaLibrary2
     exporting 192.168.1.0/24:/mnt/auxilliary
     exporting 192.168.1.0/24:/
where each of the PC's has an IP address on the LAN, e.g. demeter is 192.168.1.217

I am doing everything that I normally would do on older releases of bunsenlabs. Does anyone have a suggestion on what I should look at next to get mounting to work on my other PC's?
