Password prompt not working correctly when using NFS

[TheLalaMan]

I have set up a synced folder with NFS and now I'm required to supply my password when starting or reloading the machine. So far so good.

On the command line it all works as expected, but when using Vagrant Manager, a password prompt appears, and even though I input the correct password, it keeps reappearing and then the operation fails (see log file extract below).

Vagrant Manager: 2.7.1
Host: macOS 10.14.6
Vagrant: 2.2.6
Virtualbox: 6.0.14 r133895
Guest: CentOS

==> master: Preparing to edit /etc/exports. Administrator privileges will be required...
tee: /etc/exports: Operation not permitted
tee: /etc/exports: Operation not permitted
tee: /etc/exports: Operation not permitted
==> master: Mounting NFS shared folders...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -o vers=3,udp 192.168.56.1:/*** /var/www/***

Stdout from the command:



Stderr from the command:

mount.nfs: requested NFS version or transport protocol is not supported```

Additionally, even after implementing https://www.vagrantup.com/docs/synced-folders/nfs.html#root-privilege-requirement, it still fails with the same error. In my own terminal, everything works as expected.
