I'm trying to mount my TrueNAS-12.0-U5.1 onto a virtualbox vm client running ubuntu. And I get errors.
The command says ( couldn't copy and paste, so it's not verbatim )

Mount.nfs: access denied by server

syslog shows:

RPC: server requires stronger authentication

And the Truenas server shows this from the syslog:
Code:

Here's the rub, I have two bare metal ubuntu servers, one ubuntu desktop, and one Oracle Enterprise Linux VM (in proxmox) all able to mount the NFS share. I readily admit I don't understand the UI interface for the ACL's so I've just chmoded the directory on the Truenas server to 777. The user is the same uid/gid across my home lab, even in the truenas box. I can mount on anything else except my clients running in virtualbox. I've tried different OS's, different OS versions (LTS vs the latest and greatest), I've tried mounting with NFS4 options, I've tried mounting with "-o resrvport " ( might be spelled wrong, going from memory here) and I sill can't mount the system.

The only thing I haven't mentioned that might matter is that my virtualbox host is a Windows 10 box.

Does anyone have an idea of how I can correct this so I can mount on my virtualbox client?
