I haven't used CentOS7 for several years, so I was ignoring this thread in the hope others could answer.
My not very trustworthy memory is that "/etc/exports" on the server needs the "insecure" option for NFS4 to work, see: https://access.redhat.com/solutions/3773891 https://access.redhat.com/solutions/3773891 for explanation and some diagnostic tests. My take on diagnostics is:
FWIW, "others" have tried changing
/home/egreshko 2001:b030:112f:2::0/64(rw,sync,insecure,no_root_squash,no_subtree_check)
to
/home/egreshko 2001:b030:112f:2::0/64(rw,sync,no_root_squash,no_subtree_check)
And the mount from an F33 system still succeeds.
[root@meimei ~]# mount -v cos7:/home/egreshko /mnt mount.nfs: timeout set for Fri Feb 26 01:59:49 2021 mount.nfs: trying text-based options 'vers=4.2,addr=2001:b030:112f:2::41,clientaddr=2001:b030:112f:2::2'
[root@meimei ~]# df -T | grep mnt cos7:/home/egreshko nfs4 29599744 5324544 24275200 18% /mnt
So, I suppose it could be another exports option. But, at 02:00 I'm not inclined to give it a go. :-) And, FWIW, the centos7 system is fully updated...
[egreshko@cos7 ~]$ sudo yum update . . No packages marked for update
