That means conntrackd did not configured the helper so far, so it
remains dormant in the kernel.
Did you add the corresponding Helper clause to conntrackd.conf?
It should be something similar to what you can find under
conntrack-tools/doc/helper/conntrackd.conf.
Please, check /var/log/conntrackd.log (or custom path in case you set
it). It should report some information regarding the helper
configuration.

This was tested with NFSv3 running both Linux in the client and the
server sides.
I'd suggest to start by getting that "disabled" issue resolved first,
then, move on to see what other problem you find.
