unRAID as NFSv4 Client

[DrEVILish]

Now this is probably me just being stupid.

I have a Synology Disk Station, running as my primary large datatank. Works great no complaints.

I've enabled NFSv4, both machines are on the same subnet.

I'm trying to connect unRAID 6.3.1 to access a NFSv4 share on the Synology

NFSv3 working

Synology :/etc/exports ->
/volume1/Media 192.168.0.0/16(rw,async,no_wdelay,insecure,no_root_squash,insecure_locks,sec=sys,anonuid=65534,anongid=65534)

unRAID: /boot/config/go ->

mount 192.168.x.x:/volume1/Media /mnt/Media

 

When I try 
mount -o vers=4 192.168.x.x:/volume1/Media /media/Media

I get error 

"mount.nfs: Protocol not supported"
