error connecting with ssl delphi 2007 indy 10 - delphi

Question

I am new to Delphi and I am assigned with a Delphi 2007 desktop application and have been asked to enable https in that application current it uses Indy 10.1.5.
Below is the code which I have written but could not get expected output.
I am not sure if the DLLs that I use are compatible with it or not.
Error I get is "error connecting with ssl"
var
IdHTTP: TIdHTTP;
Id_HandlerSocket : TIdSSLIOHandlerSocketOpenSSL;
begin
IdHTTP := TIdHTTP.Create;
try
with IdHTTP do
begin
Name := 'IdHTTP';
AllowCookies := True;
RedirectMaximum := 25;
ProxyParams.BasicAuthentication := False;
ProxyParams.ProxyPort := 0;
Request.ContentLength := -1;
Request.Accept := 'text/html, */*';
Request.BasicAuthentication := False;
Request.UserAgent := 'Mozilla/3.0 (compatible; Indy Library)';
HTTPOptions := [hoForceEncodeParams];
end;
Id_HandlerSocket := TIdSSLIOHandlerSocketOpenSSL.Create(IdHTTP);
Id_HandlerSocket.SSLOptions.Method := sslvSSLv23;
Id_HandlerSocket.SSLOptions.Mode := sslmClient;
// Id_HandlerSocket.Port:= 443 ;
IdHTTP.IOHandler := Id_HandlerSocket;
try
Result := IdHTTP.Get('https://'+WebServer+'/myfol/test_file.txt'); // this is the place where I get error
except on E : Exception do
Begin
Result := E.Message +' || '+E.ClassName ;
End
end;
finally
IdHTTP.Free;
end;
