Mount.nfs4: No such device

I have installed nfs-utils to be able to use mount.nfs and mount.nfs4. I get to this problem:

root@xxxx:~# mount.nfs -o tcp,vers=3 -vv t1/
mount.nfs: timeout set for Tue Feb 21 23:32:16 2017
root@xxxx:~# mount.nfs4 -o tcp,vers=4 -vv t1/
mount.nfs4: timeout set for Tue Feb 21 23:32:25 2017
mount.nfs4: trying text-based options 'tcp,vers=4,addr=,clientaddr='
mount.nfs4: mount(2): No such device
mount.nfs4: No such device

The first command hangs and second terminates immediately. Dmesg and /var/log/messages are not showing anything. Fyi:

root@xxxx:~# lsmod | grep nfs
lockd                  51491  3 nfsd
nfs                   108782  1 nfsv3
nfsd                   73385  0 
nfsv3                  18297  0 
sunrpc                158054  4 nfsd

Im quite sure that server support nfs4 nad has open ports since i use this share form other computers. Please any ideas what am I doing wrong?

Same issue here, seems that NFSv4 is not supported by TO. Could it be implemented?
