Can anyone confirm whether mkxminer 3.0.1 is working against a p2pool node or not?

I'm running a private p2pool node that I'm able to connect to and mine against with another PC (nvidia - ccminer) on my local network, however the amd (mkxminer) rig on the network shows it successfully connects to the node, yet does not receive a difficulty setting nor does it submit any shares. Testing it against public p2pool nodes also either fail to connect or it will print a Pool Stratum Auth error ...Service not found, Code: 32601, data: null.

The miner does slowly spin up, but I'm quite sure it's mining to the dev pool and I'm not running a charity.
