MYSController and Sensebender Gateway not Communicating

[andy5211d]

I have spent a long time going through the posts to try to figure out what my system or I am doing wrong. But from the beginning, about three/four years ago I started with MYSensors and initially integrated it with OpenHAB. Some three years ago I moved to Home Assistant. In all this time and even now the sensors using MySensors firmware have worked well. And it still do! I discovered MYSController about 6 months ago after starting out writing my own (also using Lazarus) so decided to use the that software rather then re-invent the wheel. However I can not make the software do anything useful. That is in never shows any nodes or the data between them. I can only connect to the Sensebender ethernet MQTT gateway by serial connection. The ethernet connection is connected to the Home Assistant so I know it works but get back from the IP address 'no reply'.

Using the serial connection then data is shown in the MYSController Debug tab but with errors. The messages tab does not have anything. or the Nodes tab. Using the Discover function seems to do nothing. The following is an example of the data in the debug tab. Note this gateway is NOT connected to a Controller in this instance thus the 'GWT:RMQ Fail' errors. Is ErrorFlag=255 meaning listed anywhere?

I'm sure I'm doing something fundamentally wrong as all the posts I see no one seems to have a problem connected to the gateway. I'm using version 2.3.2 of the mysensors software with some nodes using 2.3.0.

Can some one please give me a clue as to how to connect to the gateway via ethernet or point me in the right direction, is the port I should use different to the default? I would like to expand my MySensors from the existing 6 nodes (Uno and Nano, all working fine with Home Assistant) and thus think the MYSController software will be really helpful.

Thanks.
