In the same environment I noticed that changing node address from localhost:4000 to <ip>:4000 breaks NX:
The session negotioation failed.
Error: No running nodes found for this server
Work:
# /usr/NX/bin/nxserver –nodelist
NX> 104 Node list:

Doesn’t work:

running encrypted 10.10.19.152:4000 NX yes
10.10.19.152 – ip of this server
changing localhost to 127.0.0.1 breaks NX too
