Instagram blocked this script?

On part login 
```
$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug);
try {
    $ig->login($username, $password);
} catch (\Exception $e) {
    echo 'Something went wrong: '.$e->getMessage()."\n";
    exit(0);
}
```
i got error: "Something went wrong: InstagramAPI\Response\LoginResponse: Challenge required."

Instagram blocked this method?
