Can you show the incorrect and the correct config used to make it even more clear?
openSUSE 15.4 NFS Setup:

To make sure the proper NFS RPC-based services are enabled for rpcbind, use the following
command: sudo rpcinfo -p

If one of the NFS services does not start up correctly, rpcbind will be unable to map RPC requests from clients for that service to the correct port.
To allow clients to access NFS shares behind a firewall, configure the firewall by running the following commands on the NFS server:
firewall-cmd --permanent --add-service mountd
firewall-cmd --permanent --add-service rpc-bind
firewall-cmd --permanent --add-service nfs
firewall-cmd --permanent --add-port=<mountd-port>/tcp
firewall-cmd --permanent --add-port=<mountd-port>/udp
firewall-cmd --reload
Note: I used firewall-config to do the port settings.

Thanks for the feedback!
For sure, anytime to help make XCP-ng the best! 
it was a very simple fix, so I'm posting here just in case anyone else has this problem.
