zfs-9 NFS mount problem

Hi

When we want to mount zfs share as NFS we fail.

we tried all of NFS versions and on same IP block (without firewall security) we couldn't.

we are getting following error;

[gbalgp11]~#mount -v -o vers=4.0 10.230.19.64:/export/murextestftp01 /merve

mount.nfs: timeout set for Mon Jan 16 17:28:41 2023

mount.nfs: trying text-based options 'vers=4.0,addr=10.230.19.64,clientaddr=10.230.19.62'

mount.nfs: mount(2): No route to host

^C
