I have an WordPress app in which I use ACF plugin with a lot of custom post type. For example I will take one custom post type named “Events” now I have an php code that makes get request on external api and with response I import as a new posts inside custom post type. But my problem is with showing on front end of this posts. In admin panel of this custom post type i see the list of imported posts with all maped fields and with published status but in front end i can’t see this posts, I see the message “There are no past events yet.” . Most interesting, I have 3 stages: Localhost , staging and production and this problem is only in Production. I checked all wordpress settings and all date format , for all 3 stages the settings is the same 100%, but in production I have this problem.

$argsPast = array(
    'post_type' => 'event',
    'posts_per_page' => 6,
    'meta_key' => 'start_date',
    'orderby' => 'meta_value',
    'order' => 'DESC',
    'meta_query' => array(
        'relation' => 'AND',
        array(
            'key' => 'start_date',
            'value' => $first_day_of_month,
            'compare' => '<=',
            'type' => 'DATE'
        ),
        array(
            'key' => 'end_date',
            'value' => $first_day_of_month,
            'compare' => '<=',
            'type' => 'DATE'
        )
    ),
);

This is my args for get request to show in frontend page and this code is setted for all 3 stages : localhost, staging , production and the problem is only on production.
