getelementsbyname not working on diffrnrt web

Good day to all. I'm new here, so I apologize if I do something wrong.

What I'm trying to do ... I'm trying to create a Bat file that would automatically open a specific site and enter there login and password, nadimal "Login" ... Emulation of what I attended today on this site ... In the past, I did it quite well ... Here is an example. (Login and password changed)

@set @script=0 /*
@echo off
set @script=
@cscript /nologo /e:jscript "%~dpnx0"
@exit /b
*/
 
var url,login,password;
url      = "http://ift.tt/2q215fQ";
// заменить на свои учетные данные
login    = "k";
password = "gx";
 
var IE = WScript.CreateObject("InternetExplorer.Application");
IE.visible = 1;
IE.navigate(url); 
 
while (IE.Busy) {
  WScript.Sleep(200);
}
 
IE.document.getElementsByName("user")(0).value = login;
IE.document.getElementsByName("password")(0).value = password;
button = IE.document.getElementsByName("save")(0);
button.focus();
button.click();

A little time has passed and the developers have made changes to the site ... For the moment, such an algorithm does not work for some reason

@set @script=0 /*
@echo off
set @script=
@cscript /nologo /e:jscript "%~dpnx0"
@exit /b
*/
 
var url,login,password;
url      = "http://ift.tt/2pdNDCC";
// заменить на свои учетные данные
login    = "k;
password = "6m";
 
var IE = WScript.CreateObject("InternetExplorer.Application");
//IE.visible = 0;
IE.navigate(url); 
IE.visible = 1;
 
while (IE.Busy) {
  WScript.Sleep(4000);
}

IE.document.getElementsByName("user")(0).value= login;
IE.document.getElementsByName("password")(0).value = password;
button = IE.document.getElementsByName("doaction")(0);
button.focus();
button.click();

For some reason, the login and password do not appear in the forms and the button is not pressed ... Help me please. Thank you.
