Not able to NFS mount on Docker LXC

[jsmith432]

I used the Docker LXC script to install a VM and be my docker host. Everything was running smoothly. I have several containers working fine, not issues except I can't see to mount NFS on the Docker LXC. I installed nfs common. I can see the exports with showmount and I can mount the NFS shares in other machines. I tried different options in fstab, including nfs version=3, defaults, etc. Any idea what I am doing wrong?

mount.nfs: mount(2): Operation not permitted
mount.nfs: Operation not permitted

When I use -v and no options:
mount.nfs: timeout set for Sun Jun 5 07:45:53 2022
mount.nfs: trying text-based options 'vers=4.2,addr=x.x.x.12,clientaddr=x.x.x.31'
mount.nfs: mount(2): Operation not permitted

Found out that I needed a privileged container, with the feature NFS enabled under container options in Proxmox. I backed up the unprivileged and restored the container as privileged. (facepalm)
