Well, without knowing what the nfs-server uses for a configuration makes it hard to see if there
is an option that needs changing.
On Fedora systems udp is turned off by default. The nfs.conf has "# udp=n" in the [nfsd] section.
So, if I try to mount using udp I get....

And when I uncomment, change to "udp=y", and restart the server I get..

mount.nfs: timeout set for Sat Jun 26 21:43:50 2021

mount.nfs: trying 2001:b030:112f:2::53 prog 100005 vers 3 prot UDP port 20048
So, there isn't more to say. The issue is on the server side and I've no idea about that unit to
look/find a configuration.
You may need to be happy with IPv4. FWIW it is most common, and recommended, to mount using
version 4 and TCP.
