I modified the options from (rw) to (rw,sync,no_root_squash,insecure)
and after that I finally could mount it in version 4. I've tested
earlier to add the insecure option, but I'm not sure if I then
remembered to restart nfs after the changes or not. Or if it is in the
combination with the other options that made it possible.
Good that you now have it working.
Now, to go figure out why I can mount just fine when my exports file has
/home/egreshko 2001:b030:112f:2::0/64(rw)
"Logic" tells me it should fail like it was failing for you. :-) :-)
