Access denied when mounting the postgres PVC to nfs

I’m using NFS store for the back and and it is failing to mount, the Persistent Volume i’ve even given 777 -R access to see if that would resolve it an it doesn’t. I’ve also added the 999 group w/ rw access but it still fails. Does anyone have any ideas?

This is the OSS helm deployment w/ kubernetes.
