If you already can ping the nfs server, then you should check this:
1. nfsd service
2. open port on iptables
3. /etc/host.allow or /etc/host.deny

You can check share folder from nfs client with command:
showmount -e ip.nfs.server
If the folder appears, then you can start to mount that otherwise you
should check your /etc/exports again.
