    hi I update WP Cerber to 8.8.3
    and get next error on https://apartik.com/wp-admin/admin-ajax.php:

    
2021/04/02 15:10:48 [error] 574#574: *6101 upstream sent too big header while reading response header from upstream, client: 95.158.32.244, server: apartik.com, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "https://45.76.87.13:8443/wp-admin/admin-ajax.php", host: "apartik.com", referrer: "https://apartik.com/"

    wp-login.php – works fine, I have problem only with admin-ajax.php
    If I disable WP Cerber – all works fine.
    Сan you suggest the cause of the problem?

    I have
    WordPress 4.9.2
