WebRequest don't work on Wine

[Marcio Vianna]

I use MetaTrader 5 running on Linux through wine. The platform needs to connect to a site to release access to Expert Advisor that I use (WebRequest function), but MT5 can not connect to the site.

This error message appears on the wine's log: GnuTLS error: A fatal TLS alert has been received.

Attached 2 prints of my screen for a better understanding of the problem.

Can anyone help me? =)

PS.: wine version is 3.0.2

I've been read this topic before, but how do I apply this solution?

TLS relates to Transport Layer Security.

Have you tried the example ?

void OnStart() 
  { 
   string cookie=NULL,headers; 
   char   post[],result[]; 
   string url="https://finance.yahoo.com"; 
//--- To enable access to the server, you should add URL "https://finance.yahoo.com" 
//--- to the list of allowed URLs (Main Menu->Tools->Options, tab "Expert Advisors"): 
//--- Resetting the last error code 
   ResetLastError(); 
//--- Downloading a html page from Yahoo Finance 
   int res=WebRequest("GET",url,cookie,NULL,500,post,0,result,headers); 
   if(res==-1) 
     { 
      Print("Error in WebRequest. Error code  =",GetLastError()); 
      //--- Perhaps the URL is not listed, display a message about the necessity to add the address 
      MessageBox("Add the address '"+url+"' to the list of allowed URLs on tab 'Expert Advisors'","Error",MB_ICONINFORMATION); 
     } 
   else 
     { 
      if(res==200) 
        { 
         //--- Successful download 
         PrintFormat("The file has been successfully downloaded, File size %d byte.",ArraySize(result)); 
         //PrintFormat("Server headers: %s",headers); 
         //--- Saving the data to a file 
         int filehandle=FileOpen("url.htm",FILE_WRITE|FILE_BIN); 
         if(filehandle!=INVALID_HANDLE) 
           { 
            //--- Saving the contents of the result[] array to a file 
            FileWriteArray(filehandle,result,0,ArraySize(result)); 
            //--- Closing the file 
            FileClose(filehandle); 
           } 
         else 
            Print("Error in FileOpen. Error code =",GetLastError()); 
        } 
      else 
         PrintFormat("Downloading '%s' failed, error code %d",url,res); 
     } 
  }

I know nothing about programming, and I don't have access to the EA's source code.

It's best to just trash it.

Without the source code there is nothing we can do.
