----------------------------------------
For the last few days since downgrading from the beta to 2.4 one of our render nodes connects complete fine but then hangs and repeats this process over and over.
I’ve seen this behavior before and it required a server restart and that was it but this time nothing I have attempted is working

Double check that the nodes are looking at a vray license

Along with the license, please check that all machines use the same version of Vray.
Would it be also possible to show us vralog.txt file from the 192.168.0.162 machine ?
Have you also reinstalled or updated Autodesk products like Max or BackBurner ?
