im trying to connect to websocket from D365 , I have tried to connect to it using .NET library and using that DLL into my project but , the websocket close before ReciveAsync() and i don’t get any response , u can’t even find out wats the status , not able to get the response back by x++ , I’m able to get maximum no connection exceed error at times in response by RecievAsync() but at times WB closes and there’s no response i have been banging my head round this issue for a while buy can’t find a solution , can anyone provide me sample code for doing this in x++ , doing it via .NET is quite complex
I have edited this thread and added my code here and from here on ill be continuing this thread for futher clarifications
