I am trying to run a code on my cx 9020 (ARM Controller Windows CE 7 – Build 4024.53) using twincat 3 (build 4024.64). I have to call a rest api POST method. the code runs without errors and a build is produced and loaded into plc. in run mode i receive an error Socket_Err_No_Connection in one of the flags and I believe this what is creating this error.

I wrote a code from an online example I am using twincat CX9020 PLC I followed all the instructions and ended up receiving the socket error socket_err_no_conn.
