Unable to connect to Hexing HXF300 via TCP

Hello

I am trying to connect to the HXF300 via TCP. I have successfully connected to the HXE110 from the same machine in the same manner. I have tried low and high authentication with the default password of "00000000". I have also tried multiple variations of the password (6 digits, 32 digits). When connecting via the probe and using Hexview, there is an Authentication key required of 32 0's, I am not sure if this needs to be put in somewhere, although I did try to put those details in the secured connection section. Whenever I try to connect I get the "Service not available" - Operation not possible error. One of the trace messages as follows:

12:18:28 Send AARQ request.

Your assistance is greatly appreciated
