WPEngine 2FA issue

Hi, I have activated the plugin in a WPEngine WP site and after I have enabled 2FA, it gives 502 bad gateway after you enter the OTP code. I did some debugging and read WPEngine error codes docs and I’ve found that if you don’t add the ‘wpe-login=true’ to the URL query string, it fails to log you in (you can verify what I mean in this link: https://wpengine.com/support/error/#444_-_Connection_Closed_Without_A_Response).
I’ve modified the code to add the wpe-login=true in the URL here (premium.php):

// Form the URL
$url = wp_login_url().’?wpe-login=true&action=loginizer_security&uid=’.$user->ID.’&lutoken=’.$token.(!empty($_REQUEST[‘redirect_to’]) ? ‘&redirect_to=’.urlencode($_REQUEST[‘redirect_to’]) : ”).(isset( $_REQUEST[‘interim-login’] ) ? ‘&interim-login=1’ : ”);

Could be possible to have some kind of patch for this issue?
Thanks in advance,
Regards
