1: Is the nfs port open on ipv6? Use "ss -ln | grep :2049" and look
for a listening port with an IPv6 address, like:
tcp LISTEN 0 64 [::]:2049 [::]:*
2: Does your firewall allow access to port 2049 on IPv6? Use
"firewall-cmd --list-services" and look for "nfs", or use "ip6tables
-L" and look for the input chain for your default zone (possibly
IN_public_allow).
root@MyCloudEX2Ultra ~ # ss -ln | grep :2049
-sh: ss: not found
In that case you probably only have busybox's netstat, and I don't
know what flags it supports. Try "netstat -tln" and if that doesn't
work maybe "netstat -ln" to get a list of the listening ports.

The system's input chain should allow NFS traffic on IPv6 by virtue of
the ACCEPT policy. That suggests that the NFS service isn't listening
on an IPv6 network socket.
With ipv4 the mount is successful with apparently trying alternate port
and protocol automatically.

mount.nfs: trying 192.168.1.239 prog 100005 vers 3 prot UDP port 37811
Is there a way to tell ipv6 mount to use prot UDP port 37811?
