WebRequest on Virtual server Error

[hex_dev]

Hi
I am trying to migrate my EA to a virtual server provided by mql5(hosted by webzilla). It uses webrequest to get crucial information from a website(code below). This works perfect on my local machine, but on the server I get Error 4014(ERR_FUNCTION_NOT_ALLOWED).
Does anyone have an Idea on why it does not work and how to fix it?

further information: res is -1 after the WebRequest call and GetLastError returns 4014 as mentioned above


string getHtml(string url)
{
   //get the html website;
   string cookie=NULL,headers, html;
   char post[],result[];
   int res;
   int timeout=5000;
   ResetLastError();
   res=WebRequest("GET",url,cookie,NULL,timeout,post,0,result,headers);
   if(res==-1)
   {
      printf("ERROR: %d", GetLastError());
      printf("Make sure website is listed in allowed urls in EA in options");
      return "";
   }
   PrintFormat("Loaded File, size =%d bytes.",ArraySize(result));
   html=CharArrayToString(result,0,WHOLE_ARRAY,CP_ACP);  
   return html;
