I have found that hard links for regular files works well for me over NFS:

$ ln bar tata
But if I try to make hard link for symlink, then it fails:
$ ln -s foo bar

Huh. I'm not sure I even realized it was possible to hardlink symlinks.
Makes sense, I guess.
What's even the use case for hard linking a symlink? That sounds like
asking for trouble...
I think my first step debugging this would be to watch wireshark while
attempting the "ln", and see what happens. That should tell us whether
it's the client or server that's failing the operation.

I am using NFSv4 with Vagrant, here is mount entry:
172.28.128.1:PATH on /vagrant type nfs4
(rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=IP,local_lock=none,addr=IP)
I have also verified that rpc-statd is running on host.
Host machine is Ubuntu 18.04 with NFS packages version 1:1.3.4-2.1ubuntu5.3.
Will appreciate help on this.
Thanks,
Vasyl
