why my expert advisor doesnt send messages?

[Thejudg 47]

hi guys, i made an expert advisor using an indicator, every time a buy signal is detected the ea sends a message to a telegram channel i made, and is the same for sell signals. the problem is that it does not send the message, i know its not the web requests because it sends a message successfully everytime after initializing the ea, and also i know the handler and getting the indicator data works fine so i dont know whats wrong. im tired of expert advisors not working without knowing why, thats why i ask for your help
