The code has no errors for me. It works fine in my environment. If the environment is different for you, you need to adapt the code. If you have problems with the Wifi, you should start with getting the WiFi to work on your Arduino + ESP-01 connection, or switch to an ESP8266 where are lot of more tutorials available. I have listed two tutorials that you should start with. If they are working with your environment, you can have a look at the code for this project furthermore.
Looks like it's an runtime error, no compiler error.
cmd += "Host:188.8.131.52 " + server + "\r\n";
This line doesn't look correct. Can you use the "step three" and enter the lines from the function httpRequest one by one? This should lead you until the error. I think you must have a space after the "Host: "
what's the error you receive in detail?
