NFS mount - failed: RPC Error: Unable to receive

I'm trying to get familiar with NFS mounts (I'm familiar with CIFS shares). In my home lab on 9.4, using System Manager, I have followed the NFS Configuration Express Guide. Per the instructions I created a new SVM with an NFS volume and export. I'm using just the NFS protocol and UNIX security style. I have a volume called nfsc and a junction of /nfsc_NFS_volume. I installed Ubuntu version 16 in my lab with IP of 172.23.4.2. Per express guide I have created an export rule for 0.0.0.0/0 that gives access wide open access - read-only/Read-write/allow superuser access etc. I also went in the default rule and opened everything up for that rule as well (apparently needed for the root volume).

On the Linux host I have created a dir called /mnt/folder below. Then you can see the error I get when trying to mount it with a couple of different mount commands.

rondebbs@ubuntu:/$ cd /mnt
rondebbs@ubuntu:/mnt$ mkdir /mnt/folder

rondebbs@ubuntu:/mnt$ sudo mount -t nfs -o nfsvers=3,hard 172.23.2.13:/nfsc_NFS_volume /mnt/folder
mount.nfs: mount to NFS server '172.23.2.13:/nfsc_NFS_volume' failed: RPC Error: Unable to receive
rondebbs@ubuntu:/mnt$

rondebbs@ubuntu:/mnt$ sudo mount 172.23.2.13:/nfsc_NFS_volume /mnt/folder
mount.nfs: mount to NFS server '172.23.2.13:/nfsc_NFS_volume' failed: RPC Error: Unable to receive
rondebbs@ubuntu:/mnt$

From the linux host I can ping the nfsc lif at 172.23.2.13 and from the Netapp command line I can ping the Linux host at 172.23.4.2 but for some reason can not do the mount. Any ideas what I am doing wrong?

Here are the export rules I have created - everything pretty much wide open for now until I can get mounted.

cluster1::> vserver export-policy rule show -vserver nfsc -policyname nfsc
Policy Rule Access Client RO
Vserver Name Index Protocol Match Rule
------------ --------------- ------ -------- --------------------- ---------
nfsc nfsc 1 nfs 0.0.0.0/0 any

cluster1::> vserver export-policy rule show -vserver nfsc -policyname default
Policy Rule Access Client RO
Vserver Name Index Protocol Match Rule
------------ --------------- ------ -------- --------------------- ---------
nfsc default 1 nfs 0.0.0.0/0 any

cluster1::>
