I have done all the steps mentioned in the document, but when I deploy my flow to check if I can read and integer from my s7-1500 (DB1,INT6) I lost the conection to server and I recive the next error message ...

I also attach a screenshot of my flow.
I only use a S7_IN node and a debug node.
The S7-1500 (192.168.0.1) is directly connected to the X2 port of my IOT2040 (192.168.0.222) and I am directly connected with my notebook (192.168.200.50) to the X1 port of the IOT2040 (192.168.200.1)
Can you help me? Thank you very much :)
